The difference between abstract class and interface and its application(This article is provided by Zhang Yang)Abstract class and interface (Interface) are two important concepts in object-oriented programming. Since there are many similarities
The examples in this article describe the Java interface and abstract class usage. Share to everyone for your reference, specific as follows:
Interface
1 because Java does not support multiple inheritance, there is an interface where a class can
Abstract class ):
Abstract modifier is used to indicate that the modified class is incomplete and can only be used as the base class. Abstract classes and non-abstract classes are different in the following aspects:Abstract classes cannot be
Classes that cannot be initialized are called abstract classes , and they provide only partial implementations, but another class can inherit it and can create instances of them, with methods that are not implemented. An abstract class cannot be a
In Java development, we sometimes define a parent class that only describes the method, but does not write out the implementation of the method in the parent class, which is called an abstract method. Naturally, classes that contain abstract methods
Interface inheritance is also called the normalization design of the program, and this kind of thing is called abstract class.So what is abstract class?Abstract class This kind of thing, can only be inherited, can not be instantiated.If a class is

The abstract modifier is used to indicate that the class being decorated is incomplete, and that it can only be used as a base class. Abstract and non-abstract classes are different in the following ways:Abstract classes cannot be instantiated
A class that declares the existence of a method and does not implement it is called an abstract class, which is used to create a class that embodies some basic behavior, declares a method for that class, but does not implement the class in that

I will discuss abstract class and interface
For object-oriented programming, abstraction is one of its three main features (abstraction, inheritance, polymorphism). In Java, there are two ways to embody the abstraction of OOP: interfaces and abstract classes.The two are both similar and
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
