Help with linking java keyListener to graphics panel

[Fedhell]

Basically i want to make a platform game in java purely from the java 2d graphics. I have managed to link the keyListener to update variables which my graphics pane can then use to draw my images. But i cant do is get my image to refresh after the variables are updated.

I have to classes, my keyListener and my main program (ignore class names took them off a tutorial i used for the keylistener).

Anyway here is my code for the main program

package code;

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

import javax.swing.*;

public class KeyListenerDemo extends Frame
{
	public static int x = 0;
	public static int y = 0;
	
	public static void main(String[] a) 
	{
	    
		JFrame frame = new JFrame("Key input Console");
	    frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
		KeyListenerDemo test = new KeyListenerDemo();
	    JTextField textField = new JTextField();
	    frame.addKeyListener(new MyKeyListener());

	   // frame.add(textField);
	    frame.setSize(200,50);
	    frame.setVisible(true);
	}
	@SuppressWarnings("deprecation")
	KeyListenerDemo()
	{
		super("Paint Tester");
		addWindowListener(new WindowAdapter()
		{
			public void windowClosing(WindowEvent e)
			{
				System.exit(0);
			}
		});
		
		setSize(1024,768);
		
		
		repaint();
		show();
		
		//add("Center", new CvHelloApp());
	}
	public void paint(Graphics g) 
	{
			g.setColor(Color.BLUE);
			g.fillOval(50+x,50+y,10,10);	
	}


}

and here is the code from my key listener

package code;

import java.awt.event.KeyEvent;
import java.awt.event.KeyListener;

import javax.swing.JFrame;
import javax.swing.JTextField;

class MyKeyListener implements KeyListener 
{
	public void keyTyped(KeyEvent e) 
	{
		char c = e.getKeyChar();
		//System.out.println("Key Typed: " + c);
	}

	public void keyPressed(KeyEvent e) 
	{
		char c = e.getKeyChar();
		//System.out.println("Key Pressed: " + c);
		
		if (c == 'w')
		{
			KeyListenerDemo.y = KeyListenerDemo.y -5;
			System.out.println("y:"+KeyListenerDemo.y);
		}
		if (c == 's')
		{
			KeyListenerDemo.y = KeyListenerDemo.y +5;
			System.out.println("y:"+KeyListenerDemo.y);
		}
		if (c == 'a')
		{
			KeyListenerDemo.x = KeyListenerDemo.x -5;
			System.out.println("x:"+KeyListenerDemo.x);
		}
		if (c == 'd')
		{
			KeyListenerDemo.x = KeyListenerDemo.x +5;
			System.out.println("x:"+KeyListenerDemo.x);
		}
	}

	public void keyReleased(KeyEvent e) 
	{
		char c = e.getKeyChar();
		//System.out.println("Key Released: " + c);
	}
}

So basically if you run my program you can see my variables change as the w s a d keys are pressed, but what i need help with is making it so my graphics will redraw.

I know that i am using alot of bad practice in this code, right now im just focusing on getting things working then ill clean it up.

Thanks for any help,

eed help with is making it so my graphics will redraw.

Do you call repaint() after you have made changes that the paint method needs to have to draw the updated GUI?

Add a println() in paint() to show the new values of x and y it is using.

Ahh i managed to solve that problem by adding a method inside my main class that repainted it and called that method whenever keyListener updated a value. Now my problem is i need the keyListener window to always stay front, off to work now tho ill check back later, im sure that has to be a frontAlways command or something like that.

Ill post back after work, thanks for the advice.!!
