I am going to move this to the Java In General (Beginner) forum.

What do you mean by complete or general?

Do you mean "abstract" and "concrete" class?

An abstract class can contain abstract methods, meaning that the methods are declared, but have no implementation (no body). By itself, an abstract class is incomplete and cannot be instantiated. If a class contains one or more abstract methods, then the class itself must be declared abstract.

A concrete class is one that provides complete implementation, and can be used to instantiate objects.
