Now we are going to develop desktop application using AWT CLASSES in java, we teach you new way for developing java application with very easy way. First of all we design a Frame in java after doing other task. so when you ready to get started the java desktop application development.

                                                      PART - III

                         Example for Login Event in Java AWT Container

import java.awt.*;

import java.awt.event.*;                  //import Action Event classes

class MyFrame 

{

     Frame f;

     Button b1,b2;

     TextField tf1,tf2;

     Label l1,l2;

     TextArea ta1;

 

     public MyFrame()  //Creating a Constructor

     {

         f = new Frame("This is My First Frame");

         b1 = new Button("Login");

         b2 = new Button("Cancel");

         l1 = new Label("Username");

         l2 = new Label("Password");

 

 

         tf1 = new TextField("",20);

tf1.setBounds(350,100,100,80);

 

         tf2 = new TextField("",20);

tf2.setEchoChar('*');                     //Hide Charactor to the Password Fields

tf1.setBounds(350,100,100,80);

 

         ta1 = new TextArea("Write an Long Comments");

         f.setLayout(new FlowLayout());

         f.setLocation(30,40);

         f.add(l1);

         f.add(tf1);

         f.add(l2);

         f.add(tf2);

 

 

         f.add(b1);

         f.add(b2);

         f.setSize(300,400);

         f.setVisible(true);   

 

//Creating An Action to Login

         b1.addActionListener(new ActionListener()

{

public void actionPerformed(ActionEvent ae)

{

String username = tf1.getText();

String pass = tf2.getText();

   String user = "bschandel";

String password = "mspatel";

if(username.equals(user) && pass.equals(password))

{

System.out.println("Login Successful");

}

else

{

System.out.println("Login FAILED ! ");

}

}

});

//Action Event Close

 

     }

     public static void main(String args[])

    {

         new MyFrame();  //Creating an Object

    }

}
