Can anyone help me with this? I'm working on a Space Invaders Game but I want a GUI with it. Now I don't know why but my Menu keeps dissappearing behind the gameCanvas. I wrote an XML parser for my menu so I DO want a menu seeing the effort I put into it :D .

Here is my code. Hopefully anyone can come up with a solution:

package eindwerkvgo2;

import java.awt.Canvas;
import java.awt.Color;
import java.awt.Container;
import java.awt.Dimension;
import java.awt.Graphics2D;
import java.awt.Image;

import java.awt.event.KeyEvent;
import java.awt.event.KeyListener;
import java.awt.event.WindowAdapter;
import java.awt.event.WindowEvent;
import java.awt.image.BufferStrategy;
import java.util.ArrayList;

import javax.swing.*;
