Loop isn't working on cpu (JCreator)

[Jamalrus]

I have this code for my programming class and it's not working. I have compared it to other working codes in the class and there is no difference whatsoever. Any help would be appreciated!

import java.awt.*;
import java.awt.event.*;

public class Unit103 extends java.applet.Applet {
	
	Graphics screen;
	int x,y,xmove,ymove,running;
	
	public void init() {
	x=135;
	y=220;
	xmove=1;
	ymove=1;
	running=1;
	}

	public void paint(Graphics screen) {
		
		while(running<1000);{
			screen.setColor(Color.red);
			screen.fillRect(x,y,50,50);
				for(int counter=1;counter<60000;counter=counter+1){}
			screen.setColor(Color.white);
			screen.fillRect(x,y,50,50);
			if(x>350||x<0);{
			xmove=xmove*-1;}
			if(y>350||y<0);{
			ymove=ymove*-1;}
			x=x+xmove;
			y=y+ymove;
			running=running+1;
		}
	}
}

Watch for these: while(running<1000);{. A semi-colon at the end of a branch signifies that its true once.
