How do I get the same name after a successful login?

I have user class that set user.setName after verifying the user name and password from text file in login JFrame and user.getName in other frame to greet user in the main menu.

There's lots of different ways to do it, but basically it boils down to Passing Information to a Method or a Constructor.

One thing you should do is to try and decouple the process. Your "main menu" doesn't care where or how the user name is generated/gained, it only needs it. Equally, your login process doesn't care what happens after the user is validated.

To that end, you should take the time to understand the model-view-controller paradigm, you will see it a lot and will help you solve similar questions.

Basically, a "controller" will display the login view, the login view will gather the credentials and the this information will be feed back through the model for validation. When successful, the controller can pass control on to the next controller which will actually display the "main menu", providing the login model as part of the information.

Again the "how" depends a lot on the overall solution, but you want to get to the point where you have the ability to change either or both the main menu and login windows and it won't have any affect on the other
