Issues getting file text to display in dialog, and overall code review.

So i'm fairly new to Java. Below is my code.

        frame.setVisible(true);

}

Two questions.

1. Any advice on how I can write better code, anything i'm doing wrong, or anything I can do to improve it.

2. I can't get the "text" from the INI file to display in a dialog. For now. My ultimate goal is to parse the ini file and read the values into a table. Left
side will be ini variable name, right side will be current value, then beside that is the "new" value you want to replace it with.

Right now I just want to display it in dialog so I know i'm reading it. Then i'll start learning/implementing the parsing of it and putting it into a table.

So anyway. Just curious why it's not showing in the dialog, and if there's anything I can do to improve my code, since I am just learning.

Also I don't understand my editor. I am using Netbeans and I tried to make a simple implementation but it started throwing a lot of errors and wanted me to bunch of try/catch
stuff in there. Is that the proper way to do all of that. Because when I first wrote it, it was very clean. Now there is a lot of extra code that was recommended by Netbeans.

Thanks again!
