An abstract class is designed to provide a common interface for a set of related subclasses, often just to provide a template for inheritance hierarchies. It contains at least one abstract method/method signature, therefore it is not able to be instantiated. It exists solely to be extended (subclassed) by other subclasses that will actually be instantiated. By using an abstract class to group these methods, code is simplified and redundancy is reduced.
