Collision detection using threads

-----------------------------------

Just wondering where u would have the code for actually doing the collision detection in a game if u have 2 objects in the same class that extend thread.

in this code where would i put my collision detection:


public void draw()								//Draw ball
  	{
  		if (runBall == true)
  		{
    		Graphics g = box.getGraphics();
    		//g.setXORMode(box.getBackground());
    		g.drawImage(new ImageIcon("C:\\Junaid Java\\Junaid Java ISU\\Pics\\cannon 1.gif").getImage(), 0, 350, null);
    		g.dispose();
  		}
    	else if(runEnemy == true)
    	{
    		Graphics e = box.getGraphics();
    		e.drawOval(xE,yE,xELength,yELength);
    		e.dispose();
    	}
  	}

    		Graphics g = box.getGraphics();
