Question

Need this in java please

Write a program that converts between decimal, hex, and binary numbers, as shown in Figure. When you enter a decimal value in the decimalvalue text field and press the Enter key, its corresponding hex and binary numbers are displayed in the other two text fields. Likewise, you can enter values in the other fields and convert them accordingly. (c) The program converts between decimal, hex, and binary numbers.

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

import javax.swing.JFrame;
import javax.swing.JLabel;

public class Exercise16_05 extends JFrame {

   private JLabel label1;
   private JLabel label2;
   private JLabel label3;

       label3 = new JLabel("Binary ");
       jTextField1 = new JTextField();
       jTextField2 = new JTextField();
       jTextField3 = new JTextField();

       Container pane = getContentPane();
       pane.setLayout(new GridLayout(3, 2));

       setTitle("Exercise16_05");

       pane.add(label1);
       pane.add(jTextField1);

       pane.add(label2);
       pane.add(jTextField2);

       pane.add(label3);
       pane.add(jTextField3);
       setSize(250, 150);
       jTextField1.addKeyListener(new KeyListener() {

           @Override
           public void keyTyped(KeyEvent e) {
               // TODO Auto-generated method stub

           }

           @Override
           public void keyReleased(KeyEvent e) {
               // TODO Auto-generated method stub

           }

           @Override
           public void keyPressed(KeyEvent e) {
               // TODO Auto-generated method stub
               if (e.getKeyCode() == KeyEvent.VK_ENTER) {

                   String s = jTextField1.getText();
                   int n = Integer.parseInt(s);
                   jTextField2.setText(Integer.toHexString(n));
                   jTextField3.setText(Integer.toBinaryString(n));

                   // System.out.println("dfdf");
               }

           }
       }

       );

       setVisible(true);
       setDefaultCloseOperation(EXIT_ON_CLOSE);
       setVisible(true);
   }

   public static void main(String[] args) {

       new Exercise16_05();
   }

}

OUTPUT:
