Bonsoir, j'aimerai que lorsque la touche ENTRER soit pressé , que le texte "ok" s'affiche sur la console mais cela ne marche pas !

package PersoGame;

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

import javax.swing.*;

public class mainGame {
	
	int CptPlay1 = 0;
	int CptPlay2 = 0;
	
	static JFrame createFen(String titre){
		JFrame Fen = new JFrame(titre);
		Fen.setSize(500, 200);
		return Fen;
	}
	
	void createPanel(JFrame Fen) {
		JPanel prinPanel = new JPanel();
		prinPanel.setLayout(new BorderLayout());
		prinPanel.setBackground(new Color(0x34495e));
		
		//POS PLAYER
        JPanel zoneplayer1 = new JPanel();
        zoneplayer1.setPreferredSize(new Dimension(200,200));
        zoneplayer1.setBackground(new Color(0x3498db));
        prinPanel.add(zoneplayer1, BorderLayout.WEST);
        
        JPanel zoneplayer2 = new JPanel();
        zoneplayer2.setPreferredSize(new Dimension(200,200));
        zoneplayer2.setBackground(new Color(0xe74c3c));
        prinPanel.add(zoneplayer2, BorderLayout.EAST);
		
		//TEXT PLAYER
		JLabel wplay1 = new JLabel("Player 1");		
		JLabel wplay2 = new JLabel("Player 2");
		wplay1.setForeground(Color.WHITE);
		wplay2.setForeground(Color.WHITE);
		
		//TEXT RESULT
		JLabel wresul1 = new JLabel(String.valueOf(CptPlay1));
		JLabel wresul2 = new JLabel(String.valueOf(CptPlay1));
		wresul1.setForeground(Color.WHITE);
		wresul2.setForeground(Color.WHITE);
		
		//ADD ELEMENT
		zoneplayer1.setLayout(new GridLayout(2,3));
		zoneplayer1.add(wplay1);
		zoneplayer1.add(wresul1);
		zoneplayer2.setLayout(new GridLayout(2,3));		
		zoneplayer2.add(wplay2);
		zoneplayer2.add(wresul2);
		
		
		prinPanel.addKeyListener(new KeyListener() {
			
			@Override
			public void keyTyped(KeyEvent e) {
				// TODO Auto-generated method stub
				if(e.getKeyCode() == KeyEvent.VK_ENTER)
				{
					System.out.print("ok");
				}
			}
			
			@Override
			public void keyReleased(KeyEvent e) {
				// TODO Auto-generated method stub
				
			}
			
			@Override
			public void keyPressed(KeyEvent e) {
				// TODO Auto-generated method stub
				
			}
		});
		
		Fen.setContentPane(prinPanel);
	}
	
	public mainGame(JFrame Fen) {	
		createPanel(Fen);
		
	}

	public static void main(String[] args) {
		JFrame Fen = createFen("Fast & Furious 8"); // Creation de la fenetre principale
		new mainGame(Fen);
		Fen.setVisible(true);
		Fen.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
	}

}

Je pense que j'ai eu le même problème. Un moyen de le contourner est d'utiliser le KeyboardFocusManager:

KeyboardFocusManager kfm = KeyboardFocusManager.getCurrentKeyboardFocusManager();

kfm.addKeyEventDispatcher(new KeyEventDispatcher(){
	public boolean dispatchKeyEvent(KeyEvent e) {
		if(e.getID() == KeyEvent.KEY_PRESSED){
			//Touche pressée
		}else if(e.getID() == KeyEvent.KEY_RELEASED){
			//Touche lachée
		}else if(e.getID() == KeyEvent.KEY_TYPED){
			//Touche tapée
		}
		return false;
	}
});

La méthode dispatchKeyEvent(KeyEvent); est appelée à chaque event.
