I am currently trying to program a array based program. We have to make a employee class then a tester main class that holds a array of five user input employee names, salaries, and performance rating. The performance rating is used to determine a supplied raise amount. I have it basically done, but when i run the program, nothing happens even though java virtual machine is running. I have looked up and down for the error, anyone can point out what i am doing wrong?
Employee Class
public class Employee
{
private String employeeName;
private int salary;
private int performanceRating;
public Employee()
{
employeeName = "";
salary = 0;
performanceRating = 0;
}
public String getEmployeeName()
{
return employeeName;
}
public int getSalary()
{
return salary;
}
public int getPerformanceRating()
{
return performanceRating;
}
}
And this is the tester main class where the error comes in somewhere
import java.util.Scanner;
public class Tester
{
public static void main(String[] args)
{
Employee[] work = new Employee[5];
Scanner scanString = new Scanner(System.in);
Scanner scanInt = new Scanner(System.in);
String employeeName = "";
double salary = 0;
double performanceRating = 0;
String choice = scanString.nextLine();
while(choice.equals("yes"))
{
for(int i = 0; i < 5 ;i++)
{
System.out.println("What is the employee's name?");
employeeName = scanString.nextLine();
System.out.println("Enter Employee's salary");
salary = scanInt.nextInt();
System.out.println("Performance? 1 = excellent, 2 = good, 3 = poor");
performanceRating = scanInt.nextInt();
work[i] = new Employee();
}
for(int j = 0; j < 5; j ++)
if(work[j].getPerformanceRating() == 1)
{
salary = salary * 0.06;
System.out.println("Employee " + employeeName + " salary raised to " + salary);
}
else if(performanceRating == 2)
{
salary = salary * 0.04;
System.out.println("Employee " + employeeName + " salary raised to " + salary);
}
else if(performanceRating == 3)
{
salary = salary * 0.015;
System.out.println("Employee " + employeeName + " salary raised to " + salary);
}
else if(performanceRating < 5)
{
salary = salary;
System.out.println("Rating is off scale. No raise for emplyee " + employeeName);
}
System.out.println("Enter more employees? type 'yes' if you want to go again");
choice = scanString.nextLine();
}
System.out.println("Done");
}
}
The program reads from System.in. If you don't enter anything, nothing will happen.
Not sure why you have 2 Scanners instead of just one.
You have while(choice.equals("yes")) except you never prompt the user to make a choice. The program does do stuff (some of which may not all work properly), but you have to give the program input. What you can do is ask the user a question before the line String choice = scanString.nextLine();.
As a side note, you could use a switch in place of the if and else if's and it might be a little easier to read and understand.

I'm doing an assignment that asks a user to input a student name, and then quiz scores until the user chooses to stop. It then calculates the total score and the average of all those scores and outputs them to the screen.
We are moving on to the subject of inheritance and now we are requested to make a class called MonitoredStudent which extends Student. The point of the MonitoredStudent class is to check if the average is above a user inputted average and display whether the student is off academic probation.
I have got most of the program written and when I input just one score (such as 71, when the average I set is 70) it is still displaying that I am on academic probation, even though the one quiz score is above the average I set of 70.
The main issue is that no matter what integer is set for the minimum passing average, I always get a return of false.
I added the "return false" statement in the isOffProbation method as when I add an if-else statement to check if the averageScore (from the Student class) is less than or equal to minPassingAvg eclipse tells me that the method needs a return type of boolean.
public class MonitoredStudent extends Student {
int minPassingAvg;
public MonitoredStudent(){
super();
minPassingAvg = 0;
}
public MonitoredStudent(String name, int minPassingAvg) {
super(name);
this.minPassingAvg = minPassingAvg;
}
public int getMinPassingAvg() {
return minPassingAvg;
}
public void setMinPassingAvg(int minPassingAvg) {
this.minPassingAvg = minPassingAvg;
}
boolean isOffProbation() {
if(getAverageScore() >= minPassingAvg)
return true;
return false;
}
}
This is the Student super class:
public class Student{
private String name;
private double totalScore;
private int quizCount;
public Student(){
name = "";
totalScore = 0;
quizCount = 0;
}
public Student(String n){
name = n;
totalScore = 0;
quizCount = 0;
}
public void setName(String aName){
name = aName;
}
public String getName(){
return name;
}
public void addQuiz(int score){
if(score >= 0 && score <= 100){
totalScore = totalScore + score;
quizCount = quizCount + 1;
}else{
System.out.println("Score must be between 0 and 100, inclusive");
}
}
public double getTotalScore(){
return totalScore;
}
public double getAverageScore(){
return totalScore / quizCount;
}
}
This is the main method:
import java.util.Scanner;
public class MonitoredStudentTester{
public static void main(String[] args) {
Scanner scan = new Scanner(System.in);
MonitoredStudent monStu = new MonitoredStudent();
String repeat = "n";
int currentScore = 0;
int minPassAv;
System.out.println("Enter the student's name:");
String stuName = scan.next();
Student sName = new Student(stuName);
System.out.println("What is the minimum passing average score: ");
minPassAv = scan.nextInt();
Student stu = new Student();
do {
System.out.println("Enter a quiz score: ");
currentScore = scan.nextInt();
stu.addQuiz(currentScore);
monStu.setMinPassingAvg(currentScore);
System.out.println("Would you like to enter any more scores?: (Y for yes, N for no)");
scan.nextLine();
repeat = scan.nextLine();
}while(repeat.equalsIgnoreCase("y"));
String studName = stu.getName();
double totalScore = stu.getTotalScore();
double avgScore = stu.getAverageScore();
boolean offProb = monStu.isOffProbation();
System.out.println(studName + "'s Total Score is: " + totalScore);
System.out.println(studName + "'s Average Score is: " + avgScore);
System.out.println("Is " + studName + "off academic probation?: " + offProb);
}
}
You main class should be something like this.
public class MonitoredStudentTester {
public static void main(String[] args) {
Scanner scan = new Scanner(System.in);
MonitoredStudent monStu = new MonitoredStudent();
String repeat = "n";
int currentScore = 0;
int minPassAv;
System.out.println("Enter the student's name:");
monStu.setName(scan.next());
System.out.println("What is the minimum passing average score: ");
minPassAv = scan.nextInt();
do {
System.out.println("Enter a quiz score: ");
currentScore = scan.nextInt();
monStu.addQuiz(currentScore);
monStu.setMinPassingAvg(minPassAv);
System.out.println("Would you like to enter any more scores?: (Y for yes, N for no)");
scan.nextLine();
repeat = scan.nextLine();
} while (repeat.equalsIgnoreCase("y"));
String studName = monStu.getName();
double totalScore = monStu.getTotalScore();
double avgScore = monStu.getAverageScore();
boolean offProb = monStu.isOffProbation();
System.out.println(studName + "'s Total Score is: " + totalScore);
System.out.println(studName + "'s Average Score is: " + avgScore);
System.out.println("Is " + studName + "off academic probation?: " + offProb);
}
}
When using inheritance you just need to create an object of child class.
I have this code where you would search for the patient ID and when found a sub menu will show, the user would then be prompted to choose. If the user chooses bill the would then be asked to enter a transaction and it would be summed to the balance in the same object as the ID that was searched. However when the user inputs a value it always sums the value to the balance(450) in the object.
How can I fix this?
NB: it's in an array
output: adds the input to the first object only.
patient pAccount[] = new patient [10];
patient p1 = new patient("Jabari","luck",d1 ,"234-4343", "p01" ,450);
patient p2 = new patient("Lisa", "nun", d2,"311-5634" , "p02",300);
patient p3 = new patient("Kyle", "Hep",d3 ,"555-5555" , "p03",2000 );
//search array for patient ID
public static void ID(person [] pAccount) {
Scanner scan= new Scanner(System.in);
String num = scan.next();
for(int i=0; i< pAccount.length; i++) {
if (pAccount[i].getpatID().equals(num)) {
System.out.println("found");
break;
}
}
}
//sum user input to balance
public static void bill(person[] pAccount) {
Scanner in = new Scanner (System.in);
double sum;
double num= in.nextDouble();
for(int i=0; i <= pAccount.length; i++) {
person ad= pAccount[i];
sum = ((patient) ad).getbalance()+ num;
System.out.println("Balance: " +sum);
break;
}
}```
what I understood from your question is, you need to add sum to the balance of a specific object in Patient Object array. Below is the way to do,
(I excluded few member variables which I didn't get just by looking at Object creation in your question and kept only name, patId and balance in Patient Class. Also I assumed you've Constructor with all the fields)
I took your code and modified a little for you requirement. You can refer comments I added in the code snippets.
PatientMainClass.class
public class PatientMainClass {
public static void main(String[] args) {
Patient pAccount[] = new Patient[3];
Patient p1 = new Patient("Jabari", "p01", 450);
pAccount[0] = p1;
Patient p2 = new Patient("Lisa", "p02", 300);
pAccount[1] = p2;
Patient p3 = new Patient("Kyle", "p03", 2000);
pAccount[2] = p3;
//Use bill method to add Amount to existing balance of all the Patient Objects
Patient.bill(pAccount);
System.out.println();
for (int i = 0; i < pAccount.length; i++) {
System.out.println("After adding amount to the Balance of pAccount[" + i + "] is : " + pAccount[i].getBalance());
}
System.out.println();
//Use billToSpecific method to add Amount to specific Patient Object
//to billToSpecific method, pass both Patient Array and Patient ID to which you want to add Amount
Patient.billToSpecificPatient(pAccount, "p02");
System.out.println();
for (int i = 0; i < pAccount.length; i++) {
System.out.println("After adding amount to p02, Balance of pAccount[" + i + "] is : " + pAccount[i].getBalance());
}
} }
Patient.class
public class Patient {
private String name;
private String patId;
private double balance;
public Patient(String name, String patId, double balance) {
super();
this.name = name;
this.patId = patId;
this.balance = balance;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getPatId() {
return patId;
}
public void setPatId(String patId) {
this.patId = patId;
}
public double getBalance() {
return balance;
}
public void setBalance(double balance) {
this.balance = balance;
}
// This method will Add entered value i.e.. "num" to the Balance of all the Patient Objects
public static void bill(Patient[] pAccount) {
System.out.println("In bill method"); // Always try using System.out.println for Debugging
Scanner in = new Scanner(System.in);
double sum;
double num = in.nextDouble();
for (int i = 0; i < pAccount.length; i++) {
Patient ad = pAccount[i];
sum = ((Patient) ad).getBalance() + num;
ad.setBalance(sum);
System.out.println("Balance: " + sum);
// break; // Commenting break statement to add balance to all the Objects
}
}
// This method will Add entered value i.e.. "num" to the Balance of the Specific Patient Object
public static void billToSpecificPatient(Patient[] pAccount, String patId) {
System.out.println("In billToSpecific method"); // Always try using System.out.println for Debugging
Scanner in = new Scanner(System.in);
double sum;
double num = in.nextDouble();
for (int i = 0; i < pAccount.length; i++) {
if (pAccount[i].getPatId().equals(patId)) {
Patient ad = pAccount[i];
sum = ((Patient) ad).getBalance() + num;
ad.setBalance(sum);
System.out.println("Balance: " + sum);
break; // Using break statement to exit the loop once we add amount to specific Patient Object
}
}
} }
I guess, you can now resolve your issue with the help of these code snippets. Hope it is helpful.
I am new to java and I am currently trying to make a program that uses an array of 10 inputted names and ages. What I want to do is add an option so that if the user types "done" when prompted to enter a name, the program will skip straight to listing the names and ages already entered.
Code:
import java.util.Arrays;
public class array2 {
public static void main(String[] args) {
java.util.Scanner input = new java.util.Scanner(System.in);
input.useDelimiter(System.getProperty("line.separator"));
int numofpeople = 10;
Person[] persons = new Person[numofpeople];
for (int i = 0; i < numofpeople; i++) {
System.out.print("Enter the person's name: ");
String person = input.next();
System.out.print("Enter the persons's age: ");
int age = (Integer) input.nextInt();
persons[i] = new Person(person, age);
}
Arrays.sort(persons);
System.out.print("Name" + "\tAge");
System.out.print("\n----" + "\t----\n");
for (int i = 0; i < persons.length; i++) {
System.out.println(persons[i].person + "\t" + persons[i].age);
}
System.out.println("The oldest person is: " + persons[numofpeople-1].person);
System.out.println("The youngest person is: "+ persons[0].person);
}
}
class Person implements Comparable<Person> {
public String person;
public Integer age;
public Person(String s, Integer g) {
this.person = person;
this.age = g;
}
#Override
public int compareTo(Person o) {
return (this.age>o.age?1:-1);
}
}
What I'm thinking is that I need to use a boolean if statement that defines whether or not done has been entered, and if it has, then the program skips asking the user for the rest of the names and ages and instead jumps to printing the already entered ones. I am not sure on this so, any help would be appreciated!
Your thought is correct, the simplest way would be checking if person is equal to "done". If this is true, break the loop and code should continue, and it should produce the result you want.
You can do comething like this:
for (int i = 0; i < numofpeople; i++) {
System.out.print("Enter the person's name: ");
String person = input.next();
if (!person.equals("done")) {
System.out.print("Enter the persons's age: ");
int age = (Integer) input.nextInt();
persons[i] = new Person(person, age);
} else {
//print table or enter here a break; directive
}
}
If user enter done instead of any name, your program will straight to listing the names and ages already entered.
this also jumps out of the for loop and moves on to printing the list if the user types in "done":
for (int i = 0; i < numofpeople; i++) {
System.out.print("Enter the person's name: ");
String person = input.next();
if(person == "done"){break;}
System.out.print("Enter the persons's age: ");
int age = (Integer) input.nextInt();
persons[i] = new Person(person, age);
}
Trying to make it so if the user types "end", in the second input which is "Enter the first name of student", the loop automatically assigns each object in the array the attributes of "null" for id and name, and 0 for age and id, as well as breaking the outerloop. However, I get the error java.lang.NullPointerException.
Any help would be appreciated.

you fail here because you try to print students data before you initialized all elements of Studentz array:
for (int c = 0; c < numberof; ++c) {
System.out.println(Studentz[c].Snake());
}
also your code fails here by the same reason:
for (int g = i; g < numberof; ++g) {
Studentz[g].Setfirst("null"); // NPE - no Student created yet in the array
Some Possibly Helpful Tips:
Follow Java naming rules for your variables and method names, Studentz should be studentz, even for your Arrays. I know...your tired of reading that but as you progress, you'll see how beneficial it really is.
If you can, don't use multiple Scanner objects, there is no need for that in your use-case. Declare one Scanner object and stick with it. You're probably doing this because you are using the nextLine() method after the nextInt() method and you're finding that it skips the first name prompt and provides a Null String (""). This happens because the nextInt() method does not consume the newline character when the Enter key is hit. To solve this problem you would either, place the code line myObj.nextLine(); directly under the int numberof = myObj.nextInt(); code line:
int numberof = myObj.nextInt();
myObj.nextLine(); // Consume ENTER key hit
or don't use the nextInt() method at all. Instead just stick with the nextLine() method and not worry about consumption:
Scanner myObj = new Scanner(System.in);
int numberof = 0;
String val = "";
while (val.equals("")) {
System.out.println("Enter number of students");
val = myObj.nextLine();
if (!val.matches("\\d+")) {
System.err.println("Invalid number supplied!");
val = "";
continue;
}
numberof = Integer.parseInt(val);
}
System.out.println("Number of students is " + numberof);
Student[] studentz = new Student[numberof];
It's always a good idea to validate any input from the User (as shown above), even if they're in a for loop. Give the User an opportunity to make a correct entry, after all, typo's do happen.
Get rid of the outerLoop: label. As a matter of fact, try avoid ever using them if you can....and you can. It would only be on a relatively rare occasion where you might ever need one.
Give your variables meaningful names, at least to some extent. This can benefit you later on down the road when you want to read your old code in the future.
In your Student class you made yourself a this real nice method named Studentss(). Well, I think it should be a constructor instead and save yourself a lot of code entry for calls to Setter methods. After all, that's mostly what the constructor is for. Your Student class constructor can look like this:
public Student(String firstName, String lastName, int age, int id) {
this.first = firstName;
this.last = lastName;
this.age = age;
this.id = id;
}
And be used like this. You will notice that upon each iteration of the outer for loop, all the prompt answers are placed within variables then at the end of all those prompts the constructor is used instantiate a student object, for example:
studentz[i] = new Student(firstname, lastname, age, id);
Doing it this way mean that there is no need to make calls to Setter methods. There is nothing wrong with making setter calls, it's just easier using the constructor. This is demonstrated below:
Scanner myObj = new Scanner(System.in);
int numberof = 0;
String val = "";
while (val.equals("")) {
System.out.println("Enter number of students");
val = myObj.nextLine();
if (!val.matches("\\d+")) {
System.err.println("Invalid number supplied!");
val = "";
continue;
}
numberof = Integer.parseInt(val);
}
System.out.println("Number of students is " + numberof);
Student[] studentz = new Student[numberof];
for (int i = 0; i < numberof; ++i) {
String firstname = "null";
String lastname = "null";
int age = 0;
int id = 0;
boolean exitOuterForLoop = false;
// Student First Name Prompt:
// (with option to End and default remaining to null's and 0's)
while (firstname.equals("null")) {
System.out.println("Enter first name of student " + (i + 1) + " (End to stop):");
firstname = myObj.nextLine();
if (firstname.equalsIgnoreCase("end")) {
firstname = "null";
//Make all remaining Student instances null and 0
for (int g = i; g < numberof; ++g) {
studentz[g] = new Student(firstname, lastname, age, id); // Use Student class constructor
}
exitOuterForLoop = true;
break; // Exit this 'while' loop
}
// Validate first name (no numbers or crazy characters)
if (!firstname.matches("(?i)[a-z']+")) {
System.err.println("Invalid First Name! (" + firstname + ") Try Again...");
firstname = "null";
}
}
if (exitOuterForLoop) {
break; // Exit this outer 'for' loop.
}
System.out.println("Firstname is: " + firstname);
// Student Last Name Prompt
while (lastname.equals("null")) {
System.out.println("Enter last name of student " + (i + 1));
lastname = myObj.nextLine();
// Validate last name (no numbers or crazy characters)
if (!lastname.matches("(?i)[a-z']+")) {
System.err.println("Invalid Last Name! (" + lastname + ") Try Again...");
lastname = "null";
}
}
System.out.println("Last name is: " + lastname);
// Student Age Prompt
val = "";
while (val.equals("")) {
System.out.println("Enter age of student " + (i + 1));
val = myObj.nextLine();
// Validate age (digits 0 to 9 only)
if (!val.matches("\\d+")) {
System.err.println("Invalid Age Supplied! (" + val + ") Try Again...");
val = "";
}
}
age = Integer.parseInt(val);
System.out.println("Student age is: " + age);
// Student ID Prompt
val = "";
while (val.equals("")) {
System.out.println("Enter ID of student " + (i + 1));
val = myObj.nextLine();
// Validate age (digits 0 to 9 only)
if (!val.matches("\\d+")) {
System.err.println("Invalid ID Supplied! (" + val + ") Try Again...");
val = "";
}
}
id = Integer.parseInt(val);
System.out.println("Student ID is: " + id);
studentz[i] = new Student(firstname, lastname, age, id); // Use Student class constructor
}
// Display the instances of Student contained within the 'studentz[]' array.
for (int c = 0; c < numberof; ++c) {
System.out.println(studentz[c].toString());
}
The snake() method is actually just another toString() method and there is nothing wrong with that however you might want to consider using StringBuilder class to create the returned string rather than doing concatenations, for example:
public String snake() {
return new StringBuilder("Name is ").append(this.first).append(" ").append(this.last)
.append(" , Age is ").append(this.age).append(" , ID is ")
.append(this.id).toString();
}
Not overly important here but it can save you memory if you do a lot concatenating with many large strings.
This is the code I have now and it is completely butchered. I am having issues try to allow user input of a String and two doubles to go into 3 parallel arrays and then save to a .txt file. I can not figure out what is wrong could someone please assist me?
public static void addGames(int i, String[] array1, double[] array2,
double[] array3, int arrayLength, Scanner keyboard) throws IOException
{
String newName;
double newPrice;
double newRating;
if(i < arrayLength)
{
System.out.println("Please enter another game name: ");
newName = keyboard.next();
array1[i] = newName;
System.out.println("Please enter another game price: ");
newPrice = keyboard.nextDouble();
array2[i] = newPrice;
System.out.println("Please enter another game rating: ");
newRating = keyboard.nextDouble();
array3[i] = newRating;
i++;
}
else
{
System.out.println("There is no more room to store games: ");
}
PrintWriter gamerOut = new PrintWriter("Project1_VideoGames.txt");
while(i < array1.length)
{
gamerOut.write(array1[i]);
gamerOut.add(array2[i]);
gamerOut.add(array3[i]);
i++;
}
gamerOut.close();
}
for (int j = 0; j < i; ++j) {
gamerOut.println(array1[j] + "\t" + array2[j] + "\t" + array3[j]);
No need to say the names are too imaginative for me. Make a
public class Game {
String name;
double price;
double rating;
}
Check if this is what you want.
Instead of having 3 arrays, I encapsulated all in a Gameclass.
public class Game {
private String name;
private double price;
private double rating;
public Game(String name, double price, double rating){
this.name = name;
this.price = price;
this.rating = rating;
}
#Override
public String toString(){
String ret = "";
ret = ret + name + " / " + price + " / " + rating;
return ret;
}

And this is what I came with for your addGames function. It only takes 1 parameter now: the number of games you want to write in the file.
public static void addGames(int gamesNumber) throws IOException
{
int i = 0;
String newName;
double newPrice, newRating;
Scanner keyboard = new Scanner(System.in);
ArrayList<Game> array = new ArrayList<Game>();
while(i < gamesNumber)
{
System.out.println("Please enter another game name: ");
newName = keyboard.next();
System.out.println("Please enter another game price: ");
newPrice = keyboard.nextDouble();
System.out.println("Please enter another game rating: ");
newRating = keyboard.nextDouble();
System.out.println();
Game game = new Game(newName, newPrice, newRating);
array.add(game);
i++;
}
System.out.println("There is no more room to store games. ");
PrintWriter gamerOut = new PrintWriter("Project1_VideoGames.txt");
i = 0;
while(i < array.size())
{
gamerOut.println(array.get(i));
i++;
}
gamerOut.close();
System.out.println("The games have been written in the file");
}
You probably want to handle some errors while reading the users input or handle exceptions from the FileWriter but I'll leave that to you.
Also, I've changed to PrintWriter#println method instead of PrintWriter#write and override the toString method in the Game class. You may want to change the implementation of that too.
Hope this helped.
