    Default program will not end

    I'm new to java and have NO idea why this won't work :S. I think its the Boolean but I'm not sure why.

    public abstract class Core {

    public int[] player = null;{
    player = new int[5];
    player[0] = 1000;
    player[1] = 100;
    player[2] = 25;
    player[3] = 10;
    }

    public int[] norris = null;{
    norris = new int [5];
    norris[0] = 1000;
    norris[1] = 100;
    norris[2] = 25;
    norris[3] = 10;
    }

    public boolean trackanimation = false;


    // FIREBALL
    public void fballdmg(){
    norris[0] = norris[0] - (player[2]*2); //50
    }

    public void fireball(){
    faniloop();
    if (trackanimation = true){
    fballdmg();
    refresh();
    s.update();
    trackanimation = false;
    }
    }

    private static DisplayMode modes[] = {
    new DisplayMode(1440,900,32,0),
    new DisplayMode(1440,900,24,0),
    new DisplayMode(1440,900,16,0),
    };
    public void loadimg(){
    // PICTURES
    playerF = new ImageIcon("E:\\ProjectSTUFF\\PlayerINFOFRAME.jpg") .getImage();
    playerN = new ImageIcon("E:\\ProjectSTUFF\\NorrisINFOFRAME.jpg") .getImage();
    // BACKGROUND
    bg = new ImageIcon ("E:\\ProjectSTUFF\\BG.jpg").getImage();
    Image fire1 = new ImageIcon("E:\\ProjectSTUFF\\FIREBALL1.jpg").getIm age();
    Image fire2 = new ImageIcon("E:\\ProjectSTUFF\\FIREBALL2.jpg").getIm age();
    Image fire3 = new ImageIcon("E:\\ProjectSTUFF\\FIREBALL3.jpg").getIm age();
    Image fire4 = new ImageIcon("E:\\ProjectSTUFF\\FIREBALL4.jpg").getIm age();
    // ANIMATION
    f = new Animation();
    f.addScene(fire1, 500);
    f.addScene(fire2, 200);
    f.addScene(fire1, 200);
    f.addScene(fire2, 250);
    f.addScene(fire1, 250);
    f.addScene(fire2, 250);
    f.addScene(fire1, 250);
    f.addScene(fire2, 250);
    f.addScene(fire3, 500);
    f.addScene(fire4, 250);
    loaded = true;
    }

    // ANIMATIONS
    private Animation f;

    // PICTURES
    private Image bg;
    private Image playerF;
    private Image playerN;

    // BOOLEAN
    private boolean loaded;
    public boolean running;

    // SCREEN
    protected Screen s;

    // stop
    public void stop(){
    running = false;
    }

    // call
    public void run(){
    try{
    init();
    loadimg();
    gameloop();
    }finally{
    s.restoreScreen();
    }
    }

    // set to full screen
    public void init(){
    s = new Screen();
    DisplayMode dm = s.findFirstCompatibleMode(modes);
    s.setFullScreen(dm);
    Window w = s.getFullScreenWindow();
    w.setFont(new Font("Arial", Font.BOLD,50));
    w.setBackground(Color.BLACK);
    w.setForeground(Color.BLACK);
    running = true;
    }

    // game loop
    public void gameloop(){
    long startTime = System.currentTimeMillis();
    long runTime = startTime;
    refresh();
    s.update();
    while(running){
    }
    }

    // animation loop
    public void faniloop(){
    long startingTime = System.currentTimeMillis();
    long runTime = startingTime;
    while (runTime - startingTime <3150){
    long timePassed = System.currentTimeMillis() - runTime;
    runTime += timePassed;
    Graphics2D g = s.getGraphics();
    f.update(timePassed);
    refresh();
    drawf(g);
    s.update();
    g.dispose();
    trackanimation = true;
    try{
    Thread.sleep(5);
    }catch(Exception ex){}
    }
    }

    // update screen
    public void update(long timePassed){}

    // paint
    public synchronized void paintUI(Graphics g){
    if(loaded){
    g.drawImage(bg, 0,0,null);
    g.drawImage(playerN, 1030,0,null);
    g.drawImage(playerF, 0,700,null);
    }
    }

    //refresh
    public void refresh(){
    Graphics2D g = s.getGraphics();
    paintUI(g);
    String norrisHP = new Integer(norris[0]).toString();
    String playerHP = new Integer(player[0]).toString();
    g.drawString(norrisHP, 1097, 116 );
    g.drawString(playerHP, 70, 818);
    g.dispose();
    }


    // draw f
    public synchronized void drawf(Graphics2D g){
    g.drawImage(f.getImage(), 50,280,null);
    }
    }



    THIS IS TH EKEYPRESS i have the whole keypress working just not the ESCAPE

    // Key pressed
    public void keyPressed(KeyEvent e){
    int keyCode = e.getKeyCode();
    if(keyCode == KeyEvent.VK_ESCAPE){
    System.out.println("KEYPREZ ESC");
    stop();
    }
    // FIREBALL
    if(keyCode == KeyEvent.VK_1){
    fireball();
    e.consume();
    }
    else{
    e.consume();
    }
    }

    When posting code, please use code tags, and preferably boil your problem down to an SSCCE that we can copy and paste to see the issue.

    Why are you doing your painting like that? Recommended reading: Lesson: Performing Custom Painting (The Java™ Tutorials > Creating a GUI With JFC/Swing)

    What loop does this get stuck in?

    It never gets past the gameloop

    Okay, so when do you expect it to exit that? What happens instead?

    When i put a system.out.pr in they key press ESCAPE it prints it, but it doesn't execute the stop(): properly. It should change the Boolean running to false and end the gameloop, then going to finally and restoring the screen. It just does nothing.

    So what happens when you put a println in the stop() method? Does it properly set the boolean to false?

    public void stop(){
    running = false;
    System.out.println(running);
    }


    it will print false

    Is that the same variable your loop is checking against? Are you sure?

    Without an SSCCE I'm only guessing, but you're either using two different variables with the same name, or you're dealing with multiple threads that are caching the variable value. Try declaring the variable volatile.

    Odd i was following up with the while loop.
    public void gameloop(){
    long startTime = System.currentTimeMillis();
    long runTime = startTime;
    refresh();
    s.update();
    while(running){
    System.out.println("stuck");
    }
    }

    This made it go threw, just needed a command to continue.
