Problem with game applet

[Topias Järvinen]

I have been trying to do a simple reaction game applet.. I have been trying for hours to make "aika" increasing when you press ENTER but I havent figured it out!
So I would like to get some help for this issue.. Sorry for being such a "noob" and I thank beforehand.

 public void init() {
    Val = Color.WHITE;
    Pun = Color.RED;
    Sin = Color.BLUE;
    Teksti = Color.BLACK;
    resize(640,420);
    addKeyListener(this);
    Thread thread = new Thread(this);
    thread.start();
 }
 

public void keyTyped(KeyEvent e) {}     
public void keyPressed(KeyEvent e) {
if(e.getKeyCode() == KeyEvent.VK_ENTER){
frozen = false;
}
e.consume();
}        
public void keyReleased(KeyEvent e){
if(e.getKeyCode() == KeyEvent.VK_ENTER){
}
}        

 public void run(){
     while (on == true) {
     if(frozen == false){
     aika++;    
     }    
     try{
     Thread.currentThread().sleep(1);
     }catch(InterruptedException e){
     }
     repaint();
     }
     }
  

 public void uptade (Graphics g) {
   if(tuplaI == null){
   tuplaI = createImage(this.getSize().width,this.getSize().height);
   tuplaG = tuplaI.getGraphics();
   }
   tuplaG.setColor(Val);
   tuplaG.fillRect(0, 0, this.getSize().width, this.getSize().height);
   g.drawImage(tuplaI, 0, 0, this);  
   paint(tuplaG);
   }  
  
 public void paint (Graphics g) { 
    g.setColor(Teksti);
    Font Fontti = new Font("Arial",Font.BOLD,25);
    g.setFont(Fontti);         
    g.drawString("Press Mouse1 when the box becomes red.",80,90); 
    while(aika<0){
    g.setColor(Sin);
    g.fillRect(220,120,100,100); 
    }    
    while(aika>0){
    g.setColor(Pun);
    g.fillRect(220,120,100,100);
    }
    } 
    }

if (frozen = false)

You're missing a very important character here. I didn't look at the rest of the code, so there may be other issues.

Oh! but thats not the problem..

You should also get in the habit of using @Override annotations. You've got another typo that would have been caught by that.

Also, sleeping for 1 millisecond is too short. Sleep at least for 50 or 100.
