Java abstract class Application-template method pattern

Template methods Mode (Templete method)

Defining the skeleton of an algorithm in an operation, and delaying the implementation of some mutable parts into subclasses, the template method pattern allows subclasses to redefine some specific steps of the algorithm without altering the structure of an algorithm.

Cases:
