Question:

Program:

import java.awt.*;

import java.awt.event.*;

public class extraRegistrationForm {

public static void main(String[] args) {

Frame f = new newRegistrationFrame("Registration Form");

f.setSize(250, 300);

f.setVisible(true);

}

}

//Frame class

class newRegistrationFrame extends Frame {

TextField t1,t2;

public newRegistrationFrame(String title) {

super(title);

setLayout(null);

setBackground(Color.white);

Label l1=new Label("Enter your name:");

l1.setBounds(10, 40, 120, 50);

Label l2=new Label("Enter your Mobile no:");

l2.setBounds(10, 70, 120, 50);

add(l1);

add(l2);

t1=new TextField();

t1.setEditable(true);

t1.setBounds(130, 55, 100, 20);

t2=new TextField();

t2.setBounds(130, 85, 100, 20);

t2.setEditable(true);

add(t1);

add(t2);

//Add  button to frame and attach listener

Button b = new Button("Submit");

b.setBounds(30, 150, 100, 30);

add(b);

b.addActionListener(new ButtonListener());

Button b1 = new Button("Clear");

b1.setBounds(140, 150, 100, 30);

add(b1);

b1.addActionListener(new ButtonListener());

//Attach window listener

addWindowListener(new WindowCloser());

}

//Listener for button

class ButtonListener implements ActionListener {

Label t=new Label();

public void actionPerformed(ActionEvent evt) {

if(evt.getActionCommand().equals("Submit")) {

//If we Have Print It On Console
System.out.println("Successfully Submitted");

/* 
If we have print It on The Awt Window
  t.setText("Successfully Submitted");

 t.setBounds(100, 210, 150, 30);

 add(t);
*/

}

else if(evt.getActionCommand().equals("Clear")) {

t1.setText("");

t2.setText("");

}

//Listener for window

class WindowCloser extends WindowAdapter {

public void windowClosing(WindowEvent evt) {

System.exit(0);

}

}

}
