Hey I Got Some Error In My Code.
Heres My Code.

package com.game.main;

import java.awt.Canvas;
import java.awt.Graphics;
import java.awt.image.BufferStrategy;

public class Game extends Canvas implements Runnable{
	
	private static final long serialVersionUID = 6877995293538150068L;
	
	public static final int WIDTH = 640, HEIGHT = WIDTH / 12 * 9;
	
	private boolean running = false;
	private Thread thread;

	public Game(){
		new Window(WIDTH, HEIGHT, "BASIC TITLE", this);
	}

	public synchronized void start(){
		thread = new Thread(this);
				thread.start();
		running = true;
	}
	
	public synchronized void stop(){
	try{
		thread.join();
		running = false;
		}catch(Exception e){
			e.printStackTrace();
		}
		
	}

	public void run(){
		long lastTime = System.nanoTime();
		double amountOfTicks = 60.0;
		double ns = 1000000000 / amountOfTicks;
		double delta = 0;
		long timer = System.currentTimeMillis();
		int frames = 0;
		while(running){
			long now = System.nanoTime();
			delta += (now - lastTime) / ns;
			lastTime = now;
			while(delta >= 1){
				tick();
				delta--;
			}
			if(running)
				render();
			frames++;
			
			if(System.currentTimeMillis() - timer > 1000){
				timer += 1000;
				System.out.print1n("FPS: " + frames);    >>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>MARK<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<
				frames = 0;
			}
		}
		stop();
	}
	
	private void tick(){
	
	}
	
	private void render(){
		BufferStrategy bs = this.getBufferStratedy();
		if(bs == null){
			this.createBufferStratedy(3);
			return;
		}
		
		Graphics g = bs.getDrawGraphics();
		
		
		g.dispose();
		bs.show();
		
	}
	
	public static void main(String args[]){
		new Game();
			
	}
	
}


I Marked The String With A ">MARK<"

The Error Says "The method print1n(String) is undefined for the type PrintStream"

Any Help?

Is that the character 1 instead of the letter el? Use ctrl-space to do
name completion.

It should be an el not a one. Type "System.out." and then hit
Ctrl-space and you'll see what method names are valid.

Yup. It's "println", not "print1n". Use the letter 'l' (lower case "L") (the one between "k" and "m" alphabetically), not the digit '1' (one).
