Code with explanation in comment line:

========================

import java.applet.Applet;

import java.awt.*;

import java.awt.event.*;

// i am implementing ActionListener Interface for actionPerformed abstract method

public class JavaApplication42 extends Applet implements ActionListener

{

   

    Button b1; //declaring variable

    String msg="";

    public void init()

    {

        b1=new Button("Doggy"); //defining button name Doggy

        add(b1); // adding button in the GUI

        b1.addActionListener(this); //defining action for the button click event

    }

    public void paint(Graphics g)

    {

        g.drawString(msg, 50, 50); //displaying the output bow bow

    }

   

    @Override

    public void actionPerformed(ActionEvent e) {

       String h=e.getActionCommand();

       if(h.equals("Doggy"))

       {

           msg="Bow Bow";

       }

       repaint();

    }

   

}

===================================================================

If you use Java Swing for GUI then you have to take jFrame and the drag one jbutton and one jLabel from the swing control then change the jbutton text property to “Doggy” and then double click on the button

And write the code :

private void jButton1ActionPerformed(java.awt.event.ActionEvent evt) {                                        

       jLabel1.setText("Bow Bow"); //you have to write this line of code

    }
