What is the difference between super class and sub class?

In Java, the superclass, also known as the parent class , is the class from which a child class (or a subclass) inherits its constructors, methods, and attributes .

The super keyword refers to superclass (parent) objects. It is used to call superclass methods, and to access the superclass constructor. The most common use of the super keyword is to eliminate the confusion between superclasses and subclasses that have methods with the same name .

The difference between the Superclass and Subclass is that Superclass is the existing class from which new classes are derived while Subclass is the new class that inherits the properties and methods of the Superclass .

Object is the root of a hierarchy of classes. The subclass inherits state and behavior in the form of variables and methods from its superclass. … A subclass inherits state and behavior from all of its ancestors. The term superclass refers to a class’s direct ancestor as well as all of its ascendant classes .
