When to use static methods

Question

I am wondering when to use static methods? Say if I have a class with a few getters and setters, a method or two, and I want those methods only to be invokable on an instanc

Answer 1

Static methods are not associated with an instance, so they can not access any non-static fields in the class.

You would use a static method if the method does not use any fields (or only static fields) of a class.

If any non-static fields of a class are used you must use a non-static method.
