Thread: How to get keys pressed by the user to control the unit in a game.

I am making a game and i want it to work like this:

1): the users presses a key and gets a player asigned to him/her.
2): The user can use the arrow keys or w/s/d/a to control the unit.
3): The space bar key is pressed and a shot is fired.

and allot more things.

i have this code (just a simple code, not yet my game code) that just starts about getting key from the user.

import java.awt.event.*; 
import javax.swing.*; 
 
public class KeyStrokeTest { 
    public static void main(String[] args) { 
        JPanel panel = new JPanel(); 
 
        /* add a new action named "foo" to the panel's action map */ 
        panel.getActionMap().put("foo", new AbstractAction() { 
                public void actionPerformed(ActionEvent e) { 
                    if(e == KeyStroke.getKeyStroke(Character.valueOf('a')))
                    {
                        System.out.println(e);
                    }
                } 
            }); 
 
        /* connect two keystrokes with the newly created "foo" action: 
           - a 
           - CTRL-a 
        */ 
        InputMap inputMap = panel.getInputMap(); 
        inputMap.put(KeyStroke.getKeyStroke(Character.valueOf('a'), 0), "foo"); 
        inputMap.put(KeyStroke.getKeyStroke(Character.valueOf('a'), InputEvent.CTRL_DOWN_MASK), "foo"); 
 
        /* display the panel in a frame */ 
        JFrame frame = new JFrame(); 
        frame.getContentPane().add(panel); 
        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); 
        frame.setSize(400, 400); 
        frame.setVisible(true); 
    } 
}

when the a key is pressed it displays a message, now how do i make a deferint message, action ect. for each other key?

Thanks...
