hey, the code below is part of a basic prison program. this part of the program adds test data into two arrays, prisoners and wardens. it also sets up a new GUI. i have attempted to display the contents of the prisoners array in a text area on the JFrame. however when i compile the code i get 3 errors:

PrisonGUI.java:112: 'class' or 'interface' expected
public static void main (String args[])
^
PrisonGUI.java:116: 'class' or 'interface' expected
}
^
PrisonGUI.java:118: 'class' or 'interface' expected
^
3 errors

i know that these errors are usually caused because of to many {} however i have checked my program and it looks ok to me. i am new to the GUI side of java so any help would be much appreciated. if any of the other classes that this part of the program links to are needed to be able to understand the code then please ask.

thanks for any help **Luke**

Your declaration in main may need to look more like:

PrisonGUI p1 = new PrisonGUI();
