In the Java language, abstract classes and interface are the two mechanisms that support the definition of an abstraction class. It is the existence of these two mechanisms that gives Java a powerful object-oriented capability. Abstract class and

Java defines some methods that do not contain the method body, the implementation of the method body to the subclass of the class according to their own circumstances to implement, such a method is an abstract modified method of abstraction,

For object-oriented programming, abstraction is one of its major features. In Java, the abstraction of OOP can be embodied in two forms: interfaces and abstract classes. There are too many similarities and there are so many different places. Many

Deep understanding of Java interfaces and abstract classesAbstract is one of the most important features of object-oriented programming. In Java, there are two ways to embody the abstraction of OOP: interfaces and abstract classes. There are too
