Making a Test game, however the JFrame just doesnt load. I think it's an easy fix.

Hello.

I am making a test game to try out some things I learned, it had worked previously but after I mixed up similar file names I thought I fixed it, however now it runs with no errors at all, but doesn't display the JFrame... I setVisible(true). But still nothing shows up.

Any guidance or help would be greatly appreciated! I tried looking at tutorials and carefully analyzing the JFrame constructor portion of my class declaration...

Code java:

public void Magi()
I'm assuming by that you're referring to the constructor of the Magi class.

In that case, remove the return type VOID, and just have it as public Magi(), then it will display your JFrame.
