Reusing code is one of the many compelling features of Java. But it's not enough to replicate the code and change it, but more needs to be done.Two forms of multiplexed code:1. Grouping, generating existing class objects in a new class2. Inheritance,

Inheritance is also an important object-oriented feature, inheritance is a class-to-class relationship, in layman's terms the dog belongs to the animal class, then the dog class inherits the animal class.Inheritance in Java is single-inheritance,

  There are two types of regeneration: Synthesize and create objects of the original class in the new class. It creates a new class and treats it as a "type" of the existing class. We can take the form of the existing class as is and add new code to
