Java games rock!

I realize that using GLEventListener's display() only swaps drawing buffer to display once. Is it possible to refresh the buffer manually?

public void display(GLDrawable drawable) {
                 
   GL gl = drawable.getGL();       
gl.glColor3f(1, 1, 1);
           line(gl, x0, y0, xn, yn);      
           gl.glFlush();            

           r = (float) ((Math.random() * 9)) / 8;
           g = (float) ((Math.random() * 9)) / 8;
           b = (float) ((Math.random() * 9)) / 8;

           // This is used to slow down the animation speed... currently JOGL's
           // animator will try to draw as fast as possible, using 100% CPU...
           // this will give the CPU some breathing space.
           try {
                 Thread.sleep(1000);
           } catch (Exception ignore) {}
           
           gl.glColor3f(r, g, b);
     
            antialiasedLine(gl, x0, y0, xn, yn);
      }

Thanks,
Jim Chen
