    System.out.println(subjectName + " Class List");

What is the name of the class which contains this static method? — Gwenc37, May 01 '14 at 07:56

Since it's a static method (class method), you can call it in two ways:

NameOfClass.printClass();

or

NameOfClass someInstance = new NameOfClass(...); // create instance
someInstance.printClass();

Why? Because class methods doesn't need an instance of the class to be called, so you can call it with only using the name of the class (first way). But Java also provides the feature to call the static method using an instance of the class.

I think you are going to cause the OP more trouble, as this method is using field variables which may or not be intialised – Scary Wombat May 01 '14 at 07:36
I just answered the question. He has not provided further information. If he commented something, I would edit with the necessary changes/explanations. – Christian Tapia May 01 '14 at 07:38

You can call a static method like this:

ClassName.methodName();

So, e.g., if you're class is called SomeClass:

SomeClass.printClass();
