Today we look at the inheritance of Java's three main object-oriented features.a Java inheritanceInheritance is a cornerstone of Java object-oriented programming technology because it allows classes of hierarchical hierarchies to be created.

JavaScript has been around for more than 20 years, but there are still different comments on this prediction. Many people say that JavaScript cannot be an object-oriented language. However, the JavaScript type is very loose and there is no compiler.

Inherited:The object class is inherited by default in Python3. But the class that inherits the object class and subclass is called the new class (This is all in Python3). There is no inheritance called the Classic class (the object is not inherited

Overview:1. Multiple classes of the same attributes and functions are extracted into another class, allowing classes with unique functionality to inherit this class. 2. Class and class inheritance can be realized by extends keywordFormat:Class
