Błędy przy wyświetlaniu wielu obrazków

Witam, mam problem ponieważ próbuje wyświetlić 2 obrazki terrain.png i char.png i wyświetla sie tylko ten
który jest podawany ostatni w kodzie w tym przypadku terrain.png
Kod Okna:

 
package Me.Minecraft2D.Windows;

import javax.swing.JFrame;
import javax.swing.JPanel;

import Me.Minecraft2D.Engine.Player;
import My.Minecraft2D.Terrain.Terrain;

public class MainWindow extends JFrame 
{
	int xOkna = 994;
	int yOkna = 1280;
	static String nazwaOkna = "Minecraft2D Alpha 0.0.1";
    public MainWindow() 
    {
        super(nazwaOkna);
        JPanel Player = new Player();
         add(Player);
        JPanel Terrain = new Terrain();
        add(Terrain);
        setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        setVisible(true);
        setSize(yOkna, xOkna);
        repaint();
    }
}

Kod Terrain:

 
package My.Minecraft2D.Terrain;

import java.awt.Dimension;
import java.awt.Graphics;
import java.awt.Graphics2D;
import java.awt.image.BufferedImage;
import java.io.File;
import java.io.IOException;

import javax.imageio.ImageIO;
import javax.swing.JPanel;

public class Terrain extends JPanel
{
    private BufferedImage imageTerrain;
     
    public Terrain() {
            super();
 
        File imageFile = new File("terrain.png");
        try {
            imageTerrain = ImageIO.read(imageFile);
        } catch (IOException e) {
            System.err.println("Blad odczytu obrazka");
            e.printStackTrace();
        }
        Dimension dimension = new Dimension(imageTerrain.getWidth(), imageTerrain.getHeight());
    }

    public void paintComponent(Graphics g) {
        Graphics2D g2d = (Graphics2D) g;
        g2d.drawImage(imageTerrain, 0, 0, null);
    }

}

Kod char:

package Me.Minecraft2D.Engine;

import java.awt.*;
import java.awt.image.BufferedImage;
import java.io.File;
import java.io.IOException;
import javax.imageio.ImageIO;
import javax.swing.JPanel;
import java.awt.Dimension;


public class Player extends JPanel
{
	int xPosPlayer = 0;
	int yPosPlayer = 0;
	
		
	private BufferedImage imagePlayer;
	 
    public Player() {
    		super();
 
        File imageFile = new File("char.png");
        try {
            imagePlayer = ImageIO.read(imageFile);
        } catch (IOException e) {
            System.err.println("Blad odczytu obrazka");
            e.printStackTrace();
        }
        Dimension dimension = new Dimension(imagePlayer.getWidth(), imagePlayer.getHeight());
    }
 
    @Override
    public void paintComponent(Graphics g) {
        Graphics2D g2d = (Graphics2D) g;
        g2d.drawImage(imagePlayer, xPosPlayer, yPosPlayer, null);
    }
}

PS char.png jest na przezroczystym tle;-)
Prosze o szybka pomoc
