Hi Friend,

Try this:

import java.awt.*;
import javax.swing.*;
import java.awt.event.*;

class LoginDemo extends JFrame{
 JButton SUBMIT;
 JLabel label1,label2;
 final JTextField  text1,text2;
  LoginDemo(){
    setTitle("Login Form");
    setLayout(null);
    label1 = new JLabel();
    label1.setText("Username:");
    text1 = new JTextField(15);

    label2 = new JLabel();
    label2.setText("Password:");
    text2 = new JPasswordField(15);

    SUBMIT=new JButton("SUBMIT");
    label1.setBounds(350,100,100,20);
    text1.setBounds(450,100,200,20);
    label2.setBounds(350,130,100,20);
    text2.setBounds(450,130,200,20);
    SUBMIT.setBounds(450,160,100,20);
   add(label1);
   add(text1);
   add(label2);
   add(text2);
   add(SUBMIT);

   setVisible(true);
   setSize(1024,768);

 SUBMIT.addActionListener(new ActionListener(){
   public void actionPerformed(ActionEvent ae){
    String value1=text1.getText();
    String value2=text2.getText();
    if(value1.equals("roseindia")&&value2.equals("roseindia")){
    JOptionPane.showMessageDialog(null,"Welcome "+value1);
    }
   else{
     JOptionPane.showMessageDialog(null,"Invalid login name or password","Error",JOptionPane.ERROR_MESSAGE);
     text1.setText("");
     text2.setText("");
  }
 }
 });
  }
  public static void main(String arg[]){
   new LoginDemo();
}
}
