Trouble Getting Any Display of JFrame Components

Question

Hello all! I appreciate being able to post questions on this forum, and am grateful for anyone's help with this.
I have written a program that displays a GUI and (will) read a random word from a file for use in a Hangman-like game.
The trouble is, today I have no display (yesterday I had display just fine!). When I run the program, it opens just an empty Container with nothing inside.
Am I crazy, but does my code create valid content for a display?
Also, I use NetBeans 6.1.
Would anyone know why one day I would get good display and the next nothing?
Any advice or suggestions for my code are greatly appreciated! Thanks!

Answer 1

Thanks JSG. Yeah, I definitely have too much in my constructor for sure. I just do that because I am uneasy about creating methods that I don't know how to use well. I am just now getting the hang of using try catch statements (they are very confusing!) and also knowing how to use FileStreams correctly (that took me forever to learn, and I still need work on it). I know that I need serious study of program architecture, how to design a program well. As for now, I'm content with smalll programs that at least work (albeit clunky).
I will try to implement your suggestions about the methods and about using super, I'm sure that I could do better with them. Thanks!
