Thread: Simple program that detects my keystroke

how can i code a java program that detects my keystroke?
for example i press enter,

the program will display a string message "You Press Enter" + "<Enter key>"

is it possible to make this algorithm in java?

Check out the robot class, that should do the trick

You can use a KeyListener. You need to have some object that listens for the event, ordinarily a Component (JFrame in the example below) in which you can call addKeyListener(KeyListener) to add the KeyListener implementation.

public class Test extends JFrame implements KeyListener{
        /**Constructor*/
	public Test(){
		super();
		addKeyListener(this);
		setVisible(true);
	}
	/**Key Listener implementation*/
	public void keyPressed(KeyEvent e){
		System.out.println("Key Pressed");
	}
	public void keyReleased(KeyEvent e){}
	public void keyTyped(KeyEvent e){}
 
 
    public static void main(String[] args) {
		new Test();
    }
 
}

    public void keyPressed(KeyEvent e){
 
        int id = e.getID();
        String keyString;
 
        if (id == KeyEvent.KEY_TYPED) {
            char c = e.getKeyChar();
            keyString = "key character = '" + c + "'"; // this part
        }
        else {
            int keyCode = e.getKeyCode();
            keyString = "key code = " + keyCode + " (" + KeyEvent.getKeyText(keyCode) + ")";
        }
 
        System.out.println(keyString);
    }

sir the method only displays an uppercased character ,, if i pressed a lower case character it always
display it as an uppercased.
