XCode 3.0 Error

Your program can't run because you appear to be missing a definition for the main function in your StudentList class. Without this function, Java has no entry point and can't actually run anything so it's throwing a NullPointerException and exiting. I can't help much more without knowing more about the project.

The definition should be in the form (inside the StudentList class):

Code:

static void main( String[] args ) {
   /* Main Code Here */
}
