GUI Problem

I have now moved my Main code into the GUI project file, but there is a load of code that Netbeans is saying that is wrong.
This is the code that i have moved. It was suggested yeterday by an admin guy to move this code into my gui coded area and just put a method that refers to it.
What i am trying to do is using my FileCHooser let the user pick a file then read it in using this method below. But I get a lot of errors and i dont know what is wrong???

Erorrs are:

How did you merge the classes. Let's see your code.

Now that wont work. Rename the main method in the main class to something else and put that method inside the class with the GUI. After the filechooser create a String array with the arguments required to call that method in the main class and call it from there

You copied the whole class not just the main method. Go through these steps above and verify that you've done each of these steps and tell us if you get any errors.
