Scanner Function Element Exception No line found

I have been making this program for school and am getting stuck on a single exception from my scanner in the main function. It works with the states.txt file, but as soon as I ask for the input of the state abbreviation it throws me "Exception in thread "main" java.util.NoSuchElementException: No line found". Ive played around with it and cannot seem to get it to work. The error is on line 103.
Ive attempted to add the input string above the print statement and add the input string within the print statement with no luck. Ive rewrote it and tried to change the type of input.

Unable to throw my custom exception

I'm trying to analyze a list of albums from a file.There are 22 albums in my list and one of the items in the list is a duplicate and another is not in correct form.I'm supposed to throw two exceptions and print helpful messages on the console.My InputMismatchException is working fine, although my program should continue reading file inputs skipping the album object/line in the list where the exception occurred.Another exception is a DuplicateAlbumException, which is a custom exception.This exception should ignore the duplicate, print a helpful message on the console that mentions that the duplicate has been ignored , and only read the item one time. The following is my txt file that has inputs of albums:top20albums.txt

I hope my code blocks have enough information and explanation for you to understand my concern.But i would explicitly say it again: Why my Scanner stopped reading file input after the mismatch exception?

The problem is the .nextInt() is throwing the InputMismatchException causing the control to go out of the while loop. Refactor the code to
try {
Scanner input = new Scanner(inFile);
input.useDelimiter("\\t|[\\n\\r\\f]+");
while (input.hasNext()) {
try{
String artist = input.next();
String title = input.next();
int year = input.nextInt();
Album albumObject = new Album(title,artist,year,rank);
addAlbum(albumObject);
count ++;
rank++;
}
catch (InputMismatchException exception)
{
System.out.println("ERROR: Line "+(count+1)+": Invalid input for year. Skipping line.");
}
}
}
// This exception will not occur unless I give it a file input that does not exist.
catch (FileNotFoundException exception)
{
System.out.println("The file was not found.");
}
/* This exception works fine.However, the Scanner should continue reading the file
* inputs just skipping the 5th line where the mismatch occur.My program for some reason
* is not printing any more input after skipping the line and that is my problem.
*/
I hope this solves your problem

First of we are going to use a set, because you do not want duplicate albums.
Second we are going to say each line has an album. The reason to do this is because your Scanner will not advance when there is an input missmatch exception. Then you have another problem, where you scanner is not on the next line.
Set<Album> albums = new HashSet<>();
try(
BufferedReader reader = Files.newBufferedReader(
inFile.toPath(), Charset.forName("UTF8")
)
){
String line;
while((line = reader.readline())!=null){
Scanner input = new Scanner(line);
input.useDelimiter("\\t|[\\n\\r\\f]+");
int rank = 0;
try{
String artist = input.next();
String title = input.next();
int year = input.nextInt();
Album albumObject = new Album(title,artist,year,rank);
if(albums.add(albumObject){
rank++;
} else{
throw new DuplicateAlbumException("album: " + title + " exists");
}
} catch(InputMissmatchException exc){
//print out an error about a bad line.
} catch(DuplicateAlbumException exc){
//print out an error about a duplicate album.
}
}
} catch(IOException e){
//problem with the file
}
One more thing, your Album class needs to override hashcode.
#Override
public int hashCode(){
return title.hashCode() + artist.hashCode();
}

How do you send an array to an arraylist?

I am have trouble creating an array or object(with multiple fields) and sending it to an array-list. Any help would be greatly appreciated. I have spent hours looking through every video on YouTube with the words object and array-list in them and have been unable to find much help.
The program needs to prompt the user to pick a option (1. AddItem) then prompt the user for the name and format (dvd, vhs) and save multiple objects with these variables in an array-list. I either keep having the location where it is saved in memory returned to me or instead of multiple objects one large object is created.
Library:
import java.util.Scanner;
import java.util.ArrayList;
public class Library {
static ArrayList<Object> items = new ArrayList<Object>();
static int menuOption;
static Scanner scan = new Scanner(System.in);
public static void main(String args[]) {
String title, format;
boolean right = false;
do{
displayMenu();
if (menuOption == 1){
System.out.println("Enter Title: ");
title = scan.next();
System.out.println("Enter format: ");
format = scan.next();
addNewItem(title, format);
} else {System.out.println(items);
}
} while (!right);
}
static int displayMenu(){
System.out.println("Menu: ");
System.out.println("1. Add New Item");
menuOption = scan.nextInt();
return menuOption;
}
static void addNewItem(String title, String format){
MediaItem b = new MediaItem();
b.setTitle(title);
b.setFormat(format);
items.add(b);
}
}
MediaItem:
public class MediaItem {
String title;
String format;
MediaItem(){
title = null;
format = null
}
MediaItem(String title, String format){
title = new String();
format = new String();
}
public String getTitle() {
return title;
}
public void setTitle(String title) {
this.title = title;
}
public String getFormat() {
return format;
}
public void setFormat(String format) {
this.format = format;
}
}

The program will run if you:
1 - Change the line
static ArrayList<Object> items = new ArrayList<Object>();
to
static ArrayList<MediaItem> items = new ArrayList<MediaItem>();
2 - Change the line
System.out.println( items );
to
for ( MediaItem mi : items )
{
System.out.println( mi.getTitle() + ", " + mi.getFormat() );
}
3 - Insert a ";" at the end of the line
format = null
I did it here and it worked.

I either keep having the location where it is saved in memory returned to me
I am guessing you ran into this when you tried to either use System.out.println() to print a MediaItem, or you otherwise tried to automatically convert an object to a string. Whatever approach you took when you were seeing the memory addresses is probably the right way to do it, your problem was only in your displaying of the data.
Consider:
MediaItem item = ...;
System.out.println(item);
By default, Java doesn't know how to convert arbitrary objects to strings when you do stuff like that, and so it just spits out the class name and memory address. You either need to print the fields separately (e.g. Java knows how to display a String already), like:
System.out.println("Title: " + item.getTitle() + " Format: " + item.getFormat());
Or you can override toString() (declared in Object) to provide a custom string conversion:
class MediaItem {
...
#Override public String toString () {
return "Title: " + title + " Format: " + format;
}
}
And then you can print it directly:
System.out.println(item);
It is the default base implementation of Object.toString() that produces those strings with the memory address in them.
Based on your description, I'm guessing you had a roughly working implementation but ran into this issue and ended up changing around (and breaking) a bunch of other unrelated things to try and fix it.

How to replace words with Parallel arrays

Hello i am new to this forum. I am fairly new to Java. I am trying to convert USA to UK words so that when i input a sentence containing any of the USA words, the output will be will be the sentence but replaced with UK words. This is my attempt:
import javax.swing.JOptionPane;
public class PArraystest
{
public static void main(String [] arg)
{
String[] wordUSA = {"Cell", "Elevator", "Fries", "Gasoline", "Faucet"};
String[] wordUK = {"Mobile", "Lift", "Chips", "Petrol", "Tap"};
String changeUK = "";
String sent;
sent = JOptionPane.showInputDialog("What name do you want to search for?");
for (int i = 0; i < wordUSA.length; i++)
{
if (sent.contains(wordUSA[i]))
{
sent.replace((wordUK)[i],(wordUSA)[i]);
//break;
}
}
//if (changeUK.equals(""))
//System.out.println(" was not found.");
//else
System.out.println(sent);
}
}

Two things:
You need to use assign the string returned from replace to sent again, or sent will be unchanged`.
The replace method is public String replace(char oldChar, char newChar), so the oldChar US word should come first, followed by the UK word.
This is the correct line: sent = sent.replace(wordUSA[i],wordUK[i]);

The replace method returns a new String with the replaced text:
//sent.replace((wordUK)[i],(wordUSA)[i]);
sent = sent.replace((wordUK)[i],(wordUSA)[i]);

Two problems:
First, you should assign the replaced string back to sent.
Second, you should use replaceAll instead of replace.

There's a whole framework of functionality devoted to this in Java called internationalizaion (i18n)
While the sample below is primarily for generation origianlly I thought I'd point it out because you could probably devise how to run it in reverse as well.
Here's a snippet that shows the proper way to go about this:
http://docs.oracle.com/javase/tutorial/i18n/intro/after.html
(all code below is theirs and not my own)
Note that to run this you'll need the resource files from the site or the versions I have provided below from the site
import java.util.*;
public class I18NSample {
static public void main(String[] args) {
String language;
String country;
if (args.length != 2) {
language = new String("en");
country = new String("US");
} else {
language = new String(args[0]);
country = new String(args[1]);
}
Locale currentLocale;
ResourceBundle messages;
currentLocale = new Locale(language, country);
messages = ResourceBundle.getBundle("MessagesBundle", currentLocale);
System.out.println(messages.getString("greetings"));
System.out.println(messages.getString("inquiry"));
System.out.println(messages.getString("farewell"));
}
}
MessagesBundle.properties:
greetings = Hello.
farewell = Goodbye.
inquiry = How are you?
MessagesBundle_en_US.properties:
greetings = Hello.
farewell = Goodbye.
inquiry = How are you?
MessagesBundle_fr_FR.properties:
greetings = Bonjour.
farewell = Au revoir.
inquiry = Comment allez-vous?

Database ps statements Insertion

Trying to insert a file like this into the database
Actor: Taylor Lautner
Bio: Taylor Daniel Lautner was born in Grand Rapids, Michigan to parents, Deborah and Daniel Lautner. He, and younger sister Makena, were raised in a well-mannered, Roman Catholic household in Hudsonville, Michigan. At the age of six, Taylor began studying martial arts at Fabiano"s Karate School and he, along with his family, quickly noticed his unique and natural talent for the sport. He was soon invited to train with seven-time world karate champion Michael Chaturantabut (aka Mike Chat) and, at the age of eight, he was asked to represent his country in the twelve years and under division in the World Karate Association where he became the Junior World Forms and Weapons champion, winning three gold medals. In 2003, Taylor continued to flourish in the martial arts circuit where he ranked number one in the world for NASKA"s Black Belt Open Forms, Musical Weapons, Traditional Weapons and Traditional Forms and, at the age of twelve, he became the three time Junior World Champion.
More_Bio: However, in addition to his love for martial arts, Taylor quickly developed a love for acting at the age of seven years old when his martial arts instructor, who was involved in show business, encouraged him to audition for a small appearance in a Burger King commercial. Although he was unsuccessful, he enjoyed the experience so much that he told his parents that he wanted to pursue a career in acting. Soon, he and his family were traveling back-and-forth from their home in Michigan to California so Taylor could audition for acting roles on a regular basis. When Taylor was ten, with the frequent traveling and air fares starting to become overwhelming, his family made the crucial decision to relocate to Los Angeles where Taylor would have the advantage of being able to audition for films, television, and commercials full-time.
Reason: This is one hunky teen idol! I loved him as Jacob Black in the "Twilight" series! He is one of the best-looking guys I"ve ever seen. I was so excited when I tweeted him and he replied back once!
Fact: He played football during his freshman and sophomore year of high school. He is of German, French, Dutch, and Native American (specifically Ottawa and Potawatomi) descent. Omg! And we both like the band Kings of Leon.
Actor: Robert Pattinson
Bio: He was born on May 13, 1986, in London, England. He enjoys music and is an excellent musician, playing both the guitar and piano. When Robert was 15, he started acting in amateur plays with the Barnes Theatre Company. Afterward, he took screen role like Curse of the Ring (2004) (TV) (Kingdom of Twilight) as Giselher.
More_Bio: In 2003, Robert took on the role of Cedric Diggory in Harry Potter and the Goblet of Fire (2005). He got his role a week later after meeting Mike Newell in late 2003. He has since been cast as Edward Cullen in the highly-anticipated film, Twilight (2008/I). His music will also be heard in the film. Additionally, Robert has completed upcoming roles as Salvador Dalí in Little Ashes (2008) and Art in How to Be (2008).
Reason : Quirky, Robert Pattinson took my breath away when I first saw him as Cedric Diggory in "Harry Potter," but stole my heart when I saw him as s vampire Edward Cullen in "Twilight." Team Edward For the Win!! I just love his messy hair and thick eyebrows.
Fact: : He is an excellent musician and plays both the guitar and piano. He began taking piano lessons at age three, and classical guitar at five.

If the code has ps statements inside the loop, Information for Taylor Lautner and Robert Pattinson is inserted to the database twice, when i take it out of the while loop, only the last, Robert Pattinson is inserted. Taylor is ignored.

Your approach to getting the data is wrong. What you're trying to do is execute an update statement each time you find an actor or a bio or any such keyword. This is wrong, you should try to gather all the information first and then execute an update.
I would suggest the following approach:
Create a POJO and fill up all the information about the actor in POJO through your while loop. Maintain this in a map (where your key might be the actor's name)
Then iterate through the map, retrieve the information from the POJO for each key and create a update statement and execute your command.
A sample code might be something like this:
import java.io.BufferedReader;
import java.io.File;
import java.io.FileReader;
import java.io.IOException;
import java.util.HashMap;
import java.util.Iterator;
public class TextReader {
public static void main(String[] args) {
new TextReader().reader();
}
public void reader() {
BufferedReader br = null;
String it;
String Actor = "", Bio = "", More_Bio = "", Fact = "", Reason = "";
try {
HashMap<String, PersonData> informationMap = new HashMap<String, TextReader.PersonData>();
br = new BufferedReader(new FileReader(new File("textFile.txt")));
while ((it = br.readLine()) != null) {
if (it.startsWith("Actor: ")) {
it = it.replace("'", "\"");
// remove actor
it = it.replace("Actor: ", " ");
Actor = it;
// System.out.println(Actor);
// ps.setString(1, Actor);
}
PersonData dataVO = informationMap.containsKey(Actor) ? informationMap.get(Actor) : new PersonData();
if (it.startsWith("Bio:")) {
it = it.replace("'", "\"");
// remove actor
it = it.replace("Bio: ", " ");
Bio = it;
// System.out.println(Bio);
dataVO.setBio(Bio);
// ps.setString(2, Bio);
}
if (it.startsWith("More_Bio:")) {
it = it.replace("'", "\"");
// remove actor
// it = it.replace("More_Bio: ", " ");
More_Bio = it;
// System.out.println(More_Bio);
dataVO.setMoreBio(More_Bio);
// ps.setString(3, More_Bio);
}
if (it.startsWith("Reason:")) {
it = it.replace("'", "\"");
// remove actor
it = it.replace("Reason: ", " ");
Reason = it;
dataVO.setReason(Reason);
// System.out.println(Reason);
// ps.setString(4, Reason);
}
if (it.startsWith("Fact:")) {
it = it.replace("'", "\"");
// remove actor
it = it.replace("Fact: ", " ");
Fact = it;
dataVO.setFact(Fact);
// System.out.println(Fact);
// ps.setString(5, Fact);
}
// System.out.println(Actor + "\t" + Bio + "\t" + More_Bio + "\t"
// + Reason + "\t" + Fact);
informationMap.put(Actor, dataVO);
}
for(String actorName: informationMap.keySet()){
PersonData dataVO = informationMap.get(actorName);
System.out.println(actorName);
// === Create your preparedstatement heare and execute the update ====
}
} catch (Exception exe) {
} finally {
if (br != null) {
try {
br.close();
} catch (IOException ex) {
}
}
}
}
Your sample POJO class might look something like this:
/**
* Sample Person POJO class
*/
public class PersonData {
private String bio;
private String moreBio;
private String fact;
private String reason;
public String getBio() {
return bio;
}
public void setBio(String bio) {
this.bio = bio;
}
public String getMoreBio() {
return moreBio;
}
public void setMoreBio(String moreBio) {
this.moreBio = moreBio;
}
public String getFact() {
return fact;
}
public void setFact(String fact) {
this.fact = fact;
}
public String getReason() {
return reason;
}
public void setReason(String reason) {
this.reason = reason;
}
}
}
Note
Java naming convention states that variable names should start with a lower case. Although I followed what you had in your code for consistency's sake, I would highly recommend that you refactor your variable names
I've made one base assumption that your actor name would be unique. That is why I used it as a key in this case. If this is not true, then you might want to consider having the actor name as part of the POJO class and use another unique identifier as your key.
