title: How do I Prompt the user to enter a password before entering the main program?
body: <p>What I need to do is to prompt the user with a username and password (authentication is done locally) and if it checks out, the user would then be able to access the main program body.</p>
  
  <pre><code>public static void main(String[] args){
  
    //String input = JOptionPane.showInputDialog("Enter password to continue: ");
    //input2 = Integer.parseInt(input);
  
  
    // followed by the creation of the main frame
    new Cashier3();
    Cashier3 frame = new Cashier3();
    frame.setTitle("CASHIER 2");
    frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    frame.setVisible(true);
  </code></pre>
  
  <p>is there any quick way to go about doing this?</p>
