We can handle the Event in Applet, AWT or Swing by following three different methods:

  • Inner Class
  • Anonymous class
  • this Pointer

package com.kunal.applet;

import java.applet.Applet;
import java.awt.Button;
import java.awt.TextField;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;

public class AnonymouseButton extends Applet {

  TextField txtSource;
  Button btnToLOwer;

  public void init()
  {
     txtSource=new TextField(20);
     btnToLOwer=new Button("Lower Case");
     btnToLOwer.addActionListener(new ActionListener(){

       @Override
       public void actionPerformed(ActionEvent e) {

       String tmp=txtSource.getText();
       tmp=tmp.toLowerCase();
       txtSource.setText(tmp);

     }});

    add(txtSource);
    add(btnToLOwer);
  }
 }
