This is a continuation of Login Tutorial and Connecting to MS Access database using JCreator see here With this, I am showing you some twist that after a correct login in the program it will show another form in Java. 1. First create a java program with a filename of MainMenu.java. 2. Import the following libraries. 
  1. import javax.swing.*;
  2. import java.awt.*;
  3. import java.awt.event.*;
  4. import java.io.*;
3. Initialize the following variables below. 
  1. JDesktopPane desktop = new JDesktopPane();;
  2. 		String TITLE	= "This is another form";
  3. 		JMenuBar menubar = new JMenuBar();
  4. 		JPanel panel_Bottom = new JPanel();
  5. 		JPanel panel_Top = new JPanel();
4. Create a constructor named MainMenu. 
  1.  public MainMenu() {
  2.     	super("This is another form");
  3.         desktop.setBackground(Color.black);
  4.     	panel_Top.setLayout(new BorderLayout());
  5.      	panel_Top.setPreferredSize(new Dimension(10,150));
  6.  
  7.    		getContentPane().add(panel_Top,BorderLayout.PAGE_START);
  8.     	getContentPane().add(desktop,BorderLayout.CENTER);
  9.      	getContentPane().add(panel_Bottom,BorderLayout.PAGE_END);
  10.  
  11.  
  12.      };
5. Create a method setMain. Instead of using the Main args, we will just use this method and will call from the Login.java. 
  1. public void setMain(){
  2. 			MainMenu p1= new MainMenu();
  3.     		p1.setSize(1275,950);
  4.     		p1.setLocation(2,2);
  5.     		p1.setVisible(true);
  6.     		p1.setResizable(false);
  7. 	}
6. In your Login.java in this this previous link see here. Add the code below. 
  1. if((loginname.equalsIgnoreCase(txtuser.getText()))&&(loginpass.equalsIgnoreCase(txtpass.getText())))
  2.     			{	
  3.  
  4.  
  5.               	    MainMenu menu = new MainMenu();
  6.                     menu.setMain();		 
  7.     		    dialogmessage = "Welcome - "+loginname;
  8.                     dialogtype = JOptionPane.INFORMATION_MESSAGE;
  9.                     JOptionPane.showMessageDialog((Component)null, dialogmessage, dialogs, dialogtype);
  10.                     txtuser.setText("");
  11.                     txtpass.setText("");
  12.             		dispose();
  13.  
  14.     			}
MainMenu menu = new MainMenu() and menu.setMain() was called when the button with a correct login is clicked and it will show the MainForm.
