Hi Kapilkp,

Same time ago, I did something like that.

In login JFrame you must set the close operation as:

Java

f.setDefaultCloseOperation(JFrame.HIDE_ON_CLOSE);

And when you click on the button, you have dispose this frame:

Java

dispose();

and create a new instance of your class that store the second JFrame

Java

dispose();
JSecondFrame secondFrame = new JSecondFrame();

I hope this helps you

Best regards,
Filipe Marques

--UPDATE--

Java

// MyLogin.java
import javax.swing.*;
import java.awt.event.*;
public class MyLogin {
	private JFrame f = new JFrame("Login");
	private JButton bok = new JButton("OK");
	
	public MyLogin() {
	
		f.setDefaultCloseOperation(JFrame.HIDE_ON_CLOSE);
		f.getContentPane().add(bok);
		
		bok.addActionListener(new ActionListener() {
			public void actionPerformed(ActionEvent ae) {
				f.dispose();
				new SecondFrame();
			}
		});
		f.setSize(100,100);
		f.setVisible(true);
	}
	
	public static void main(String[] args) {
		new MyLogin();
	}
}

// SecondFrame.java
import javax.swing.*;
public class SecondFrame {
	private JFrame f = new JFrame("Second");
	
	public SecondFrame() {
	
		f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
		f.setSize(300,300);
		f.setVisible(true);
	}
}

The login JFrame is only a button and when you click it, the login window is disposed and the second window appears.

//First JFrame

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

public class Pro implements ActionListener
{
JFrame f1=new JFrame("Log In");
JLabel l1,l2;
JTextField t1,t2;
JButton b1;

Pro()
{
l1=new JLabel("User Name");
l2=new JLabel("Password");
t1=new JTextField(20);
t2=new JTextField(20);
b1=new JButton("OK");

f1.setSize(400,400);
f1.setVisible(true);
f1.setLayout(null);

f1.setDefaultCloseOperation(JFrame.HIDE_ON_CLOSE);
f1.add(l1);
f1.add(t1);
f1.add(l2);
f1.add(t2);
f1.getContentPane().add(b1);

l1.setBounds(0,30,100,30);
t1.setBounds(110,30,100,30);
l2.setBounds(0,70,100,30);
t2.setBounds(110,70,100,30);
b1.setBounds(0,120,100,30);

b1.addActionListener(this);
}

public void actionPerformed(ActionEvent e)
{
f1.dispose();
Project1 p2=new Project1();
}

public static void main(String ag[])
{
Pro p1=new Pro();
}
}

//Second JFrame
import javax.swing.*;

public class Project1
{
JFrame f1=new JFrame("Log In1");

Project1()
{
f1.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
f1.setVisible(true);
f1.setSize(400,400);
}
}
