I am currently making a video player which allows users to open/play videos which are stored on their computer. I am using JavaFX for this.My problem, is that sometimes when I click the button to load a video, a java.util.ConcurrentModificationException is raised. Other times, it's perfectly fine.I put the calls to .loadAndPlayMediaA() and .prepareMedia() (see below) inside a .runLater(Runnable) to try to prevent this, but it has not worked. My Code (below) is called by a listener on a button, "testButton". I have a class called JfxMediaPlayer which holds the method loadAndPlayMediaA(), and a class called MixingDeck which holds the method prepareMedia()
testButton.setOnAction(new EventHandler<ActionEvent>(){
@Override
public void handle(ActionEvent arg0) {
Platform.runLater(new Runnable(){
@Override

I am making a game with java in a program called greenfoot.My problem is that a sound won't play when the player dies and a Game Over screen pops up..
- I have saved the audio file in my sound map of the scenario
- Applied the good name of the file
- tested the sound effect and it's working
this is my code:
public GameOver()
{
setImage(new GreenfootImage("GAME OVER", 100, Color.BLACK, null));
Greenfoot.playSound("fail-trombone-03.wav");

I have created a playlist class that ask the user to enter a song name and etc. What I want to do is have the mp3 class plays the song that the user has entered, but I don't know how.
Here are my codes:
import java.util.Scanner;
public class PlaylistDriver
{//Start of class
public static Playlist list;
public static void main(String[] args)
{//Start of main
list = new Playlist();

I'm doing a project with very defined requirements. Input and output will be done to and from a file. Both the input and output files should have the same format. Each file will consist of a series of lines formatted as follows:
Year Rank Artist Title
That is, each line of the file will consist of the year, rank, artist, and title of a single song, with each of the fields separated by tabs ( ). Output files must maintain this format—you should be able to use the output file of one run of the program as the input to another run.
The first part of my project is to make a Song class, with 6 methods:
public static Song parse(String s) { //Parse a string of the form “Year Rank Artist Title” and create a Song object with the given values.
}
public int getYear() { //returns the year of the song
}
public int getRank() { //returns the rank of the song
[Code] .....
So far, I have worked out my Song class like this:
Java Code:
import java.util.Scanner;
public class Song {
private int year;
private int rank;
private String artist;
private String title;
[Code] ....
I know there's definitely a problem with my parsing, as I am getting the
Exception in thread "main" java.util.NoSuchElementException
when I attempt to input a test String at my variables.
Should I try using StringTokenizer and Integer.parseInt()? I think that perhaps the reason why an error is occuring is because the String is being parsed into Strings and there are no int values to be inputted into the year and rank variables.
Or is there a way to do this with Scanner?

Its a basic program that is played by 2 people. Player one is suppose to type a number and the second player is suppose to guess the number. However after I test it out, and if I guess too low or too high I get stuck in "Your guess is too low, try again." infinite loop, what is wrong.
import java.io.*;
class GuessingGame
{
public static void main (String[] args) throws IOException
{
BufferedReader stdin = new BufferedReader (new InputStreamReader (System.in));
String firstPlayer, secondPlayer;
int firstInput, secondInput;
int guessCount = 0;

I wanted to build an mp3 player as a Java project. One crucial part of the project involves being able to play an mp3 fie. I am not able to find the right api (if one exists) and am not able to find a suitable answer when searching on the web. A simple code snippet illustrating the playing of mp3 file using Java program. Also, I am using Eclipse IDE and how to import files if any importing of files is required.

I am having a problem with the JavaFX MediaPlayer playing videos with resolutions greater than 1920x1080px. For testing purpose I downloaded the example from [URL] ... and added the following error-handling:
mediaPlayer.setOnError(new Runnable) {
@Override
public void run() {
System.out.println(mediaPlayer.getError.getMessage());
System.out.println(mediaPlayer.getError.getType());
}
});
When playing a video with a resolution of 1920x1168px, the window became black and I get this console output:
[com.sun.media.jfxmediaimpl.platform.gstreamer.GSTMediaPlayer@5482fb8f] ERROR_MEDIA_INVALID: ERROR_MEDIA_INVALIDUNKNOWN
The video is encoded with h264 and aac (for audio) and is having a resolution of 1920x1168px. The error occurs with each video with a resolution greater than 1920x1080px. Vidoes with a resolution of 1920x1080px or smalle are working fine. The playback of all videos is working with VLC-Player. I tried Java 7_51 and Java 8_5.

I need to write up a code that will print the lyrics of the Green Bottles song. So it will ask the user to input a number and it will use that number to print the lyrics and then count down from that number. For example, user enters the number 5, the program will run and display:
"5 green bottles, hanging on the wall
5 green bottles hanging on the wall
and if one green bottles should fall
there will be 4 green bottles hanging on the wall
4 green bottles, hanging on the wall...." and so on.
So far I have managed to write a code that will display the number that is entered but I cant figure out how to subtract the number by 1 to continue it. My code so far:
import java.util.Scanner;
public class SomeJavaCode
{
public static void main(String[] args)
{
System.out.println("How many bottles to start with?");
[Code] ....
How to code it so that it substracts the number and repeats the rhyme till 0.

I have one question that suppose I am designing a Swing applications and I am using JFrame as Top level container.
So what is best
1)first Extends that class like
public class A Extends JFrame
{
//Do all stuff with Top Level container with gui
}
2)Or design like this from this source
[URL] ....
package components;
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
/* TopLevelDemo.java requires no other files. */
public class TopLevelDemo {
/**
* Create the GUI and show it. For thread safety, this method should be invoked from the event-dispatching thread.
*/
private static void createAndShowGUI() {
//Create and set up the window.

I am trying to create an MP3 player with a totally customized look and feel to it. I know how to do this with .net, but I must be missing something in Java.
I want to be able to NOT have to present the user with the default mediaPlayer.getControlPanelComponent() in order to control the media player. I want to be able to code it to when the user clicks on my "Play" button, I can tell the player to play the song, and so on.
so far I get this far:
try {
player = Manager.createPlayer(playit.toURI().toURL());
player.start();
//Component c = player.getControlPanelComponent();
} catch (IOException | NoPlayerException ex) {
Logger.getLogger(TagTester.class.getName()).log(Level.SEVERE, null, ex);
}
...but cannot seem to find out where to go from there.
If familiar with AxWindowMediaPlayer in .NET, I am looking for something similar to:
AxWindowMediaPlayer.Ctlcontrols.play()
when my "Play" button is clicked.

So I have a player an enemy and enemy bounds the enemy can go. I need to have the enemy track my position and when I go into the position (I am using a collision method for this) the enemy comes over at a speed of 1. My problem is the enemy jumps to me and then follows at speed of 2 (2 is the player speed). The code is wrong this is why it is jumping and I have my other problems. so my question is what is a good solution for this? I am trying to make a method to track playerposition() so what I am thinking I could do is find x, y of player then store those into an array and return the array to Enemy so he tracks.
player.java
public class Player{
int x = 100; // Location of player
int y = 200; // location of player
int xa = 0; // Representation of where the player goes
int ya = 0; // Representation of where the player goes
private int speed = 2;
[Code] .....
Please note this is not the entire code I have cut some things out that did not need to be there. Also, the code is just to get an idea of what I was thinking of doing. The ideas that are came up with are not meant to be a reflection of what I already have but, what I could add or replace.

I have already tried every possible way for removing this bug but all failed. The problem is that sometimes my player passes through the map tiles, i mean, the algorithm is like -- if not colliding, move in required direction; else if colliding, move in opposite direction. But sometimes the second condition fails i dont understand why.
private void movement(){
left=bindObject.getLeft();
right=bindObject.getRight();
up=bindObject.getUp();
down=bindObject.getDown();
bindObject.setColliding(colliding);
[Code] .....
Where bindObject is a class which contains key bindings of following keys:-
left arrow key (when pressed) , left arrow key (when released),
right arrow key (when pressed), right arrow key (when released),
up arrow key (when pressed), up arrow key (when released),
down arrow key (when pressed), down arrow key (when released)

I am creating a hangman code. So the game i am creating is 2 player, first player enters the word and second player guesses. i made the code but i don't know how to restrict the first player from adding random characters into the secret word because for my project the word can only contain letters. so i need making the code so the player 1 can only enter letters.
My code is below:
/**
* Auto Generated Java Class.
*/
import java.util.Scanner;
public class Hangman {
public static void main(String[] args) {
Scanner input= new Scanner(System.in);
String player1,player2;
int wrongguessamount = 0; //keeps the count of the amount of wrong guesses
int correctguessamount = 0; //keeps count of the amount of correct guesses
int maxincorrect=6;//makes sure the user cant guess more than 6 times

So I am trying to create a Multi-Player game in java, and I have a Game server and a Client. They normally connect with either but I would like to add a login server so that there can be an option to go to a different world then just the main one. It will have the same map and data but will be separate from the Players that are on world one per say. Now if you are on world two I would like it to have the option for you to be able to Private message players that are on World one. That is where the login server comes in to play.
I am still new at Java and would like to be able to understand Packets and how to handle them more clearly. So far I have gotten the basis of the login server connected to the server and the client connects to the server via the login server. But I am getting a bunch of "unhandled packets" and I would like to know how to handle them. Here are some bits of the code.
package com.ls.net;
import org.jboss.netty.channel.ChannelHandlerContext;
import org.jboss.netty.channel.ChannelStateEvent;
import org.jboss.netty.channel.ExceptionEvent;
import org.jboss.netty.channel.MessageEvent;
import org.jboss.netty.channel.SimpleChannelUpstreamHandler;
[Code] ....
So when I run my client this pops up in the console:
[Tue Sep 16 16:50:56 EDT 2014][LoginServer]: Finished initializing login server.
[Tue Sep 16 16:50:56 EDT 2014][SignalMultiplexer]: Unhandled packet: 15
[Tue Sep 16 16:50:56 EDT 2014][SignalMultiplexer]: Unhandled packet: 41
[Tue Sep 16 16:50:56 EDT 2014][SignalMultiplexer]: Unhandled packet: 74
[Code] ....
And here are the class's for Accounts:
package com.ls.net.codec.decoder.packets;
import org.jboss.netty.buffer.ChannelBuffer;
import org.jboss.netty.channel.ChannelHandlerContext;
import com.ls.bufutils.BufferUtils;
import com.ls.net.codec.decoder.PacketDecoder;
import com.ls.net.codec.decoder.handlers.AccountHandler;
[Code] ....

Alright, so I'm having problems with lines 11 - 55. I'm trying to calculate the possible tiles the clicked unit can be moved on and display it to the player.
The field is a 9 (columns) by 5 (rows) grid. A unit with can move tiles horizontally or vertically based on its movement.
Example: (unit = o; possible tiles = x) (assuming movement of 2).
[ ][ ][ ][ ][x][ ][ ][ ][ ]
[ ][ ][ ][x][x][x][ ][ ][ ]
[ ][ ][x][x][o][x][x][ ][ ]
[ ][ ][ ][x][x][x][][ ][ ]
[ ][ ][ ][ ][x][ ][ ][ ][ ]
I tried to calculate movement by finding out what column the unit is in, subtracting the column it wants to go to, multiplying the difference by *-1 if the difference is less than 0. Then, doing the same with rows and adding the difference of columns to the difference of rows and comparing it to the unit's movement. Unfortunately, with my code, it seems to move in any directions.
@Override
public void mouseClicked(MouseEvent e) {
if (Main.cards.size() > 0) {
mainloop: for (int i = 0; i < Main.cards.size(); i++) {
Card c = (Card) Main.cards.get(i);
int startingColumn = 0;
