How do you create a JOptionPane Java program for password verification? I am trying to create a program where you enter the username and password(made up of course) in and if it is correct, a message dialog box pops up saying it was the correct combination . Also if it is the wrong username and password, it also has a message dialog box saying it was incorrect. If it is incorrecr three times, after the third wrong dialog box, the program exits using SystemExit. lookup(String name, String password) should be used for the true or false part of the program with the authentication.... Thanks in advance! No JavaFX needed. Just using frames
