I'm trying to display some text in a JTextArea I have set up in a simple GUI. Easy right? That's what I thought, but I'm clearly not that advanced at Java. The hook is the information I want to display in the JTextArea is in a text file (file.txt).
Right now I have a main class and a class called TextArea that houses the GUI and two methods. In the main class I have set up a simple array with some text in it, and I'm able to get it to display in the JTextArea. Basically the code all works fine, the only thing I can't figure out and need to change is have the information in the array coming from a text file. So if anyone can help me figure this out I'd really appreciate it. And if there is another way to get a textfile to appear in JTextArea without putting it into an ArrayList first I'd love to know.
The only important line of code is: textArea.setText(show);
That sets the text the TextArea shows. So if you want to show it the content of a file, you'll need to read the content of the file and pass its content to this method. If you don't know how to read from a file read this (although it plays a big role, ignore the Path class for now. It is part of Java 7).
Edit: And welcome to the Javaranch.

I've pretty much figured out all of the major issues I was having trouble with, thanks to the help from the people in these forums(thanks!). The info from my text file is displaying in the JTextArea but for some reason I can only get the last line of the file to display. There are 10 lines in the text file that I'm trying to display.
Here's my updated code:
