IMPORTANT: Probably a rookie question, but I'm clueless on how to solve it.
I have a UI class which I use to input a name and gender (geslacht) using a scanner (see code below)
private static void geefNaamEnGeslacht(int aantal) {
String naam, geslacht;
for (int i = 0; i < aantal; i++) {
System.out.print("Wat is de naam van speler " + (i + 1) + " (min 6 tekens, max 12 tekens)? ");
naam = sc.next();
naam += sc.nextLine();
System.out.print("Wat is het geslacht van speler " + (i + 1) + "(man=m vrouw=v)? ");
geslacht = sc.next();
System.out.println(naam.length());
try {
dc.maakSpelerAan(naam, geslacht.charAt(0));
} catch (NameLengthNotValidException e) {
System.out.println(e.getMessage());
i--;
}
}
}
In my domain class I check the length of that name in the setter, but it always throws the exception, no matter what I tried. When debugging, the length of any name I picked checks out to be between 6 and 12 characters strangely enough. (see code below)
public final void setNaam(String naam) {
int lengte = naam.length();
if (naam.length() < 6 || naam.length() > 12) {
throw new NameLengthNotValidException("Je naam moet tussen 6 en 12 tekens liggen!");
}
this.naam = naam;
}
Any ideas or tips are apreciated.
EDIT1 code of dc.maakSpelerAan
public void maakSpelerAan(String naam, char geslacht){
s.maakSpeler(naam, geslacht);
}
EDIT2 code of s.maakspeler
public void maakSpeler(String naam, char geslacht){
if (spelCompleet()) {
throw new ListFilledException("De lijst met spelers is vol !");
}
if (!controleerUniekeNaam(naam)) {
throw new NotUniqueNameException();
}
Kaart[] schatkaarten = new Kaart[STARTAANTAL];
Kaart[] kerkerkaarten = new Kaart[STARTAANTAL];
for (int i = 0; i > STARTAANTAL; i++) {
schatkaarten[i] = stapels.get(SCHATKAART).geefBovensteKaart();
kerkerkaarten[i] = stapels.get(KERKERKAART).geefBovensteKaart();
}
try{
Speler s = new Speler(naam, geslacht);
s.getKaarten(kerkerkaarten, schatkaarten);
spelers.add(s);
}catch (IllegalArgumentException | NameLengthNotValidException e){
throw e;
}
if (spelCompleet()) {
//UC2
spelers.get(EERSTESPELERINDEX).setBeurt(true);
}
}
EDIT3 REPOST WITH CORRECT IMAGE Image of variable "naam" right before it goes in the IF loop while debugging. MINLENGTHNAAM and MAXLENGTHNAAM are set to 6 and 12 respectively in an interface class.
EDIT4 Code in my interface class for MINLENGTH AND MAXLENGTH
public interface SpelInfo {
final int STARTAANTAL = 2;
final int MAXAANTALPUNTEN = 10;
final int INDEXNAAMDETAILS = 0;
final int INDEXGESLACHTDETAILS = 1;
final int INDEXPUNTENDETAILS = 2;
final int MINAANTALSPELERS = 3;
final int MAXAANTALSPELERS= 6;
final int EERSTESPELERINDEX = 0;
final int MAXLENGTHNAAM = 6;
final int MINLENGTHNAAM = 12;
final int AANTALSTAPELS = 2;
final char MAN = 'm';
final char VROUW = 'v';
final int SCHATKAART = 0;
final int KERKERKAART = 1;
}
In "Edit4" you need to change the green line into:
if(naam.length() > MAXLENGTHNAAM || naam.length() < MINLENGTHNAAM) {
Just a little logical issue :)

So I'm coding my text-based game with world generation and my friend coded the world generation. He's away right now so I have to ask this.
The code should generate an array with the X and Y positions of chests that spawn in random positions. The packages used are: java.util.Scanner,
java.util.Arrays,
java.util.Random,
Class is declared but I'm not including it in this snippet.
The Code for the method worldgen():
static double[] worldgen() {
//coded by *my friend, name censored*
int random_int_1 = 0;
int random_int_2 = 0;
int x;
int y;
int chest_x;
int chest_y;
double[] chest_x_values;
double[] chest_y_values;
int mineral_x;
int mineral_y;
// chest_x_and_y_values[something (or else)] = chest_x_values[something];
// chest_x_and_y_values[something else] = chest_y_values[something];
Random rand1 = new Random();
int num_of_chests = rand1.nextInt(100);
chest_x_values = new double[num_of_chests];
chest_y_values = new double[num_of_chests];
while (random_int_1 <= num_of_chests)
{
Random rand2 = new Random();
chest_x = rand2.nextInt(301);
System.out.println(chest_x);
chest_x_values[random_int_1] = chest_x;
System.out.println(Arrays.toString(chest_x_values));
if(random_int_1 <= num_of_chests) {
random_int_1++;
System.out.println(random_int_1);
}
}
while (random_int_2 <= num_of_chests)
{
Random rand3 = new Random();
chest_y = rand3.nextInt(301);
chest_y_values[random_int_2] = chest_y;
random_int_2 = random_int_2 + 1;
}
int random_int_3 = num_of_chests;
random_int_1 = 0;
random_int_2 = 0;
double[] chest_x_and_y_values = new double[random_int_3 = random_int_3*2+1];
while (random_int_1 <= random_int_3) {
chest_x_and_y_values[random_int_1] = chest_x_values[random_int_1];
random_int_1 = random_int_1 + 1;
}
chest_x_and_y_values[random_int_1+1] = -1;
while (random_int_2 <= random_int_3) {
chest_x_and_y_values[random_int_1 + 1 + random_int_2] = chest_y_values[random_int_2];
random_int_2 = random_int_2 + 1;
}
return chest_x_and_y_values;
}
public static void main(String[] args) {
//coded by EnZon3
Scanner uIn = new Scanner(System.in);
System.out.println("-------------------------------");
System.out.println(" *game name censored* ");
System.out.println(" 1: Generate new world.. ");
System.out.println(" 2: Generate w/ custom seed.. ");
System.out.println(" 3: See world data ");
System.out.println(" 4: Exit ");
System.out.println("-------------------------------");
int option = uIn.nextInt();
if (option > 4) {
System.err.println("Error 0x1: Not an option");
}
while (option != 4) {
if (option == 1) {
double[] world = worldgen();
System.out.println(Arrays.toString(world));
}
}
}
The error I get is:
Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException:
Index 77 out of bounds for length 77 at
.worldgen(.java:35) at .main(.java:86)
I've tried tweaking the values but that didn't work
while (random_int_1 <= num_of_chests)
This should be < (strictly less than), remember arrays are 0 indexed.
while (random_int_2 <= num_of_chests)
Same thing here
while (random_int_1 <= random_int_3) {
chest_x_and_y_values[random_int_1] = chest_x_values[random_int_1];
random_int_1 = random_int_1 + 1;
}
random_int_3 is 2 * num_of_chests +1, and chest_x_values is a list of length num_of_chests. In this part, random_int_1 can go all the way up to 2 * num_of_chests +1 which is higher than chest_x_values.
I have this code that asks for numbers and then introduces them into an array, then, I have to separate positives, negatives and nulls.
I'm having trouble with creating the array of each type.
For example, I start the code, I introduce 5 numbers(1,2,3,4,5), then goes to the method that assings the positives to the positiveArray, negatives to the negativeArray and nulls to the nulledArray.
But when I print, for example, positiveArray, only adds at the final index
I read that everytime I call ArrayUtils.add(), it should be placing the number at the end, but not like what I'm getting, that should be like this:
int[] numbers= new int[4];
numbers = ArrayUtils.add(numbers , 1);
numbers = ArrayUtils.add(numbers , 2);
numbers = ArrayUtils.add(numbers , 3);
numbers = ArrayUtils.add(numbers , 4);
numbers = {1,2,3,4}
Or am I wrong?
I'm using ApacheCommons
Thanks

}
The problem is that you recreate a new array at each iteration, like this line (in cantidadPositivos()):
numerosPositivos = new int[pos];
You should define those arrays before entering the for cycle.
public void cantidadPositivos(){
int i = 0;
numerosPositivos = new int[pos];
numerosNegativos = new int[neg];
numerosNulos = new int[nulos];
for(i = 0; i < cantidadElementos; i++)
{
if(numeros[i] >= 1)
{
numerosPositivos = ArrayUtils.add(numerosPositivos, numeros[i]);
System.out.println(Arrays.toString(numerosPositivos));
}
else if (numeros[i] <=-1)
{
numerosNegativos = ArrayUtils.add(numerosNegativos, numeros[i]);
}
else
{
numerosNulos = ArrayUtils.add(numerosNulos, numeros[i]);
}
}
JOptionPane.showMessageDialog(null, "De los [ "+cantidadElementos +" ] elementos en el vector:\n\nPositivos: "+ pos +"\n\nNegativos: "+ neg +"\n\nNulos: " + nulos + "\n", "Información que cura", JOptionPane.INFORMATION_MESSAGE, null);
}
When you use new int[4] you get an array like [0, 0, 0, 0] since int is primitive so it cannot be null.
ArrayUtil.add does not replace those 0 values, since they are valid entries, so it just appends your new number to the array.
So i would suggest to start with an empty array.
I marked where I got the exception and I don't know why it's happening. This code finds the popularity and meaning of a name that the user types in . It also makes a graph(but it doesn't work)
The files are too long to put on here but on line examples are: names.txt:
Brenda f 0 0 0 0 917 42 14 13 40 115 123 172 426 (popularity), meanings.txt:
BRITTANY f English From the name of the region in the northwest of France, called in French Bretagne.(meaning)
1. Why am I getting this exception?
2. How do I fix the exception?
3. Why isn't my graph drawing the bars (in method changingGraph)
Example Console Output:
Name: aaron
Aaron f 0 0 0 0 0 0 0 0 0 883 0 0 0
AARON m English, Biblical From the Hebrew name ??????? ('Aharon) which is most likely of unknown Egyptian origin.

I need to do a Credit card number validation.
When I googled this I found the org.apache.commons.validator.CreditCardValidator. But seems like it is not working correctly.
When I pass a non-digit character also it porvides true.
Code for Apache CreditCardValidator:
String ccNumber = "378282246310005";
CreditCardValidator creditCardValidator = new CreditCardValidator();
if(!creditCardValidator.isValid(ccNumber)) throw new Exception("Credit Card Number is not a valid one!");
Then, I wrote following methods to validate credit card numbers based on the card type and the card number (using the luhn's algorithm).
CardType validator (null if an invalid card type)
public String getCCType(String ccNumber){
String visaRegex = "^4[0-9]{12}(?:[0-9]{3})?$";
String masterRegex = "^5[1-5][0-9]{14}$";
String amexRegex = "^3[47][0-9]{13}$";
String dinersClubrRegex = "^3(?:0[0-5]|[68][0-9])[0-9]{11}$";
String discoverRegex = "^6(?:011|5[0-9]{2})[0-9]{12}$";
String jcbRegex = "^(?:2131|1800|35\\d{3})\\d{11}$";
String commonRegex = "^(?:4[0-9]{12}(?:[0-9]{3})?|5[1-5][0-9]{14}|6(?:011|5[0-9][0-9])[0-9]{12}|3[47][0-9]{13}|3(?:0[0-5]|[68][0-9])[0-9]{11}|(?:2131|1800|35\\d{3})\\d{11})$";
try {
ccNumber = ccNumber.replaceAll("\\D", "");
return (ccNumber.matches(visaRegex) ? "VISA" : ccNumber.matches(masterRegex) ? "MASTER" :ccNumber.matches(amexRegex) ? "AMEX" :ccNumber.matches(dinersClubrRegex) ? "DINER" :ccNumber.matches(discoverRegex) ? "DISCOVER" :ccNumber.matches(jcbRegex) ? "JCB":null);
} catch (Exception e) {
e.printStackTrace();
}
return null;
}
CardNumber validator using Luhn's algorithem.
public boolean isValidCardNumber(String ccNumber){
try {
ccNumber = ccNumber.replaceAll("\\D", "");
char[] ccNumberArry = ccNumber.toCharArray();
int checkSum = 0;
for(int i = ccNumberArry.length - 1; i >= 0; i--){
char ccDigit = ccNumberArry[i];
if((ccNumberArry.length - i) % 2 == 0){
int doubleddDigit = Character.getNumericValue(ccDigit) * 2;
checkSum += (doubleddDigit % 9 == 0 && doubleddDigit != 0) ? 9 : doubleddDigit % 9;
}else{
checkSum += Character.getNumericValue(ccDigit);
}
}
return (checkSum != 0 && checkSum % 10 == 0);
} catch (Exception e) {
e.printStackTrace();
}
return false;
}
I want to know,
Is there any other thrid party class to validate the credit cards
other than the org.apache one?
Is there any issue with the my code?
(I tested it for several times. So far so good. I just want to know
if you could spot something that I didn't.)

I doesn't see problem with code. May be you can cross check following points:
Are you able to select single / multiple row(s)? Or check what jTableObject.getRowSelectionAllowed() returns
Does your code gets called only after selecting rows. Your code should be executed after some rows are selected so that it can return you expected values.
Listener which calls above mentioned code, is it added to table.
Small points but better to cross check :).
As shown in this working example, you can add a ListSelectionListener to your table's ListSelectionModel and see if anything comes through. It may help pin down where things have gone awry: for example, a local table reference that shadows the intended one.
