Think of it like a child inheriting properties from its Java Inheritance Inheritance means access the properties and features of one class into another class.

The class who is going to provide its features to another class will be called base class and the class who is using the properties and features of another class will be called derived Object oriented programming in java is very important and having a clear understanding is important for every java programmer.

I explain using an The objects in your example use inheritance, which causes a chain of constructors to be called. When using inheritance a class inheriting from another (subtype) must call the constructor of the class it extends (super type).When a type hierarchy exists, meaning several classes extend from each other in a chain, the calls to the super constructor propagate to the first class in chain that does.
