Keyboard-Inputs aren't recognized/initialized

[DoMyBest]

Hello,

I wanted to create a simple window with the LWJGL and a key input request which closes the window.
I also wanted to create the classes in seperated packages, so it's more organized.
The window displays but if I press that certain key nothing happens.

It would be great if you could help me.

Thanks!

Here is the Main class:

package bb.main;
 
import bb.input.Input;
import bb.main.render.SimpleRenderer;
 
public class Main {
	public static void main(String[] args){
		SimpleRenderer 	createWindow 	= new SimpleRenderer();
		Input			input			= new Input();
 
		createWindow.Render();
		input.checkKey();
	}
}

Here is the SimpleRenderer class:

package bb.main.render;
 
import org.lwjgl.LWJGLException;
import org.lwjgl.opengl.Display;
import org.lwjgl.opengl.DisplayMode;
 
public class SimpleRenderer {
	public void Render(){
 
		try{
			Display.setDisplayMode(new DisplayMode(1280, 720));
			Display.setTitle("MISSING TITLE!");
			Display.create();
		} catch (LWJGLException LWex){
			LWex.printStackTrace();
			System.exit(0);
		}
 
		while(!Display.isCloseRequested()){
 
			Display.update();
		}
		Display.destroy();
	}	
}

And here is the Input class:

package bb.input;
 
import org.lwjgl.input.Keyboard;
import org.lwjgl.opengl.Display;
 
public class Input {
	public void checkKey(){
		while(Keyboard.next()){
			if(Keyboard.getEventKeyState()){
				if(Keyboard.getEventKey() == Keyboard.KEY_ESCAPE){
					Display.destroy();
					System.exit(0);
				}	
			}
		}
		Display.destroy();
	}
}

Two words: Game Loop.

Before you do anything else, read the LWJGL basics on the wiki: http://lwjgl.org/wiki/index.php?title=LWJGL_Basics_1_(The_Display) there is the first one. Everything you ever do in LWJGL should follow that basic pattern.

I understand that you have probably just come from learning Swing and things are a bit new but all the answers you need to make your idea work are on that one page I have linked. Study it and only if you still cannot make it work come back here.
