Answer 1

First you need import java.awt.event package and make your class implements KeyListener.

import java.awt.event.*;
class Ex implements KeyListener {

Ex {
//listen to key listener
addKeyListener(this);
}
//therefore you need to override all the methods in it.

@Override
public void keyTyped(KeyEvent e) {

//we will use keyTyped method

//storing the keyCode typed in a variable.
var code = e.getKeyCode();
Sytem.out.println(code);

//printing the key name
System.out.println(KeyEvent.getKeyText(code));
}

@Override
public void keyPressed(KeyEvent e) {

}

@Override
public void keyReleased(KeyEvent e) {
}
