Login Dialog

First, we develop a login module that authenticate user based on username and password. To make it simple, we hard-code the username and password in this module. You can use different methods such as reading user’s information from database or file.

Second, we create login dialog that extends JDialog class and provides users with layout including:

Whenever user enters the username and password and clicks the login button, we call Login module above to authenticate the user. In the login dialog, we also have a property called succeeded to indicate that the user has provided correct username and password.

Third, in the main program, we create a new instance of login dialog LoginDialog. To show login dialog, we use method setVisible(true).
