#key listener problem

[mij1_7]

hello
can anyone help me plz with this cheetah and rabbit game, i want the cheetah
to move one step up, down, left and right when the keys are pressed.
i managed to take one step up however it doesnt do it again when pressed,
any hints.

import java.awt.GridLayout;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import java.awt.event.KeyEvent;
import java.awt.event.KeyListener;
import java.util.*;

import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.JLabel;
import javax.swing.JOptionPane;

public class Platform implements KeyListener {

private JFrame window = new JFrame("C&R");
static int N;
private JLabel[][] grid = new JLabel[N][N];

Position posC;
Position posR;

public Platform() {

// parses the string into integer
N = Integer.parseInt(JOptionPane.showInputDialog(null,
"enter dimensions"));
grid = new JLabel[N][N];
window.setSize(50 * N, 50 * N);
window.setDefaultCloseOperation(JFrame.EXIT_ON_CLO SE);
window.getContentPane().setLayout(new GridLayout(N, N));
window.addKeyListener(this);

for (int i = 0; i < N; i++)
for (int j = 0; j < N; j++) {

grid[i][j] = new JLabel(".");
window.getContentPane().add(grid[i][j]);
// create the i,j button
// add the i,j button to the window

}
posC = new Position('C', 4, 4);
posR = new Position('R', 3, 3);

window.setVisible(true);
Display();
}

public void Display() {
for (int i = 0; i < N; i++)
for (int j = 0; j < N; j++) {

grid[i][j].setText(".");
}
grid[posC.getX()][posC.getY()].setText("C");
// grid[posR.getX()][posR.getY()].setText("R");
}

public void keyPressed(KeyEvent e) {
int key = e.getKeyCode();

if (key == KeyEvent.VK_UP) {
posC.goUp();
Display();
}
}

public void keyReleased(KeyEvent e) {

}

public void keyTyped(KeyEvent e) {

}

public static void main(String[] args) {

new Platform();
}
}

thank you.

hello
go up is the method which reduces the y coordinate by 1.
the initiual value is {code} posC = new Position('C', 4, 4); {code}

Display shows the cheetah on the grid on position 4,4.
However when i press up in run time it doesnt do anything.

I will greatly appreciate any help given here. Thank you all in advance.
{code}

public void Display() {


for (int i = 0; i < N; i++)
for (int j = 0; j < N; j++) {

grid[i][j].setText(".");

}
grid[posC.getX()][posC.getY()].setText("C");

}

{code}
then the keypressed method is suppose to change the value of y and display it in the new position which is suppose to be (3,4).
{code}
public void keyPressed(KeyEvent e) {
int key = e.getKeyCode();

if (key == KeyEvent.VK_UP) {
posC.goUp();
System.out.println("hello");
Display();
}
{code}

This code is 98% working.
It displays the beginnings of a basic game board,
the Cheeta responds to the arrow keys,
and the display update is clean.

The only problem I find is that the Up/Down keys
send the Cheeta left and right, and the Left/Right keys
send the Cheeta up and down.
