import javax.swing.JOptionPane;
public class PasswordManager
 
{
 
	private static String masterPassword = "secret3";
 
    public static void main(String[] args)
 
{
 
	boolean done= false;
 
	while(!done)
	{
 
	String password= JOptionPane.showInputDialog(null, "Enter Password:");
 
	if (password==null)
 
 
	{
finish();
 
}
 
try
{
if (checkPassword==true)
{
	done = true;
}
}
catch
}
	JOptionPane.showMessageDialog(null, "Your entry was incorrect! Please try again...",null JOptionPane.ERROR_MESSAGE);

import javax.swing.JOptionPane;
public class PasswordManager
 
{
	private static String masterPassword = "secret3";
 
    public static void main(String[] args)
}
{
	boolean done= false;
 
	while(!done)
}
 
	String password= JOptionPane.showInputDialog(null, "Enter Password:");
 
	if (password.equals(password)
{
 
finish();
 
}
 
	try
{
	if (checkPassword.equals(checkPassword)
 
	done = true;
 
}
	catch
{
	JOptionPane.showMessageDialog(null, "Your entry was incorrect! Please try again...",null JOptionPane.ERROR_MESSAGE);
 
	JOptionPane.showMessageDialog(null, "Your entry was correct!");
 
public static void finish()
 
}
	return code;
    System.exit(0);
 
}
