get user input

[game2d]

i am having two problems. 1st is i want to print 3 char from string. i dont want to print ontop of each other so i am doing 600*i. but this not really working.

g.drawString(username[i], 600*i, 300);

2nd question is that if user hit 3 keys at same time than in string it will add only one and string will be full. bc user hit 3 times at same time.


full code

//paint method
for(int i = 0; i < username.length; i++){
	g.drawString(username[i], 600*i, 300);
	System.out.print(username[i]);
}

int z = 0;
String username[] = new String[3];

public void keyPressed(KeyEvent e)
    {
        int keys = e.getKeyCode();

        username[z] = KeyEvent.getKeyText(keys);
        e.consume();                  
    }

public void keyReleased(KeyEvent e)
{ 
    int keys = e.getKeyCode();

    z++;
    e.consume(); 
}

OK, I'm a little confused...

1. You say you want to print characters from Strings, but it looks like you're printing whole Strings. From what you say I'd imagine something like:
   

   char[] username = {' ',' ',' '};
   public void paint(...) {
     //...
     for(int i=0; i<username.length(); i++) {
       g.drawString("" + username[i], 600*i, 300);
       System.out.print(username[i]);
     }
     //...
   }

   or maybe
   

   String username = "";
   public void paint(...) {
     //...
     for(int i=0; i<username.size(); i++) {
       g.drawString("" + username.get(i), 600*i, 300);
       System.out.print(username.get(i));
     }
     //...
   }

   or even
   

   String username = "";
   public void paint(...) {
     //...
     g.drawString(username.substring(0,3), 600, 300);
     System.out.print(username.substring(0,3));
     //...
   }

2. What you could try is synchronizing the keyPressed function; I don't know whether this will work, but it's something you could try. This also means, that an array is no longer an option unless you synchronize that manually; switching to a synchronized collection, e.g. a synchronized ArrayList, is probably the best solution. This is what that would look like:
   

   List username = Collections.synchronizedList(new ArrayList());
   
   public synchronized void keyPressed(KeyEvent e) {
     int keys = e.getKeyCode();
     username.add(KeyEvent.getKeyText(keys));
     e.consume();
   }

   If that doesn't work you may want to have a look at Key Bindings.

Does that help?
