Java Inheritance (Subclass and Superclass)
In Java, it is possible to inherit attributes and methods from one class to another. We group the "inheritance concept" into two categories:

subclass (child) - the class that inherits from another class
superclass (parent) - the class being inherited from
To inherit from a class, use the extends keyword.

class Arithmetic {
    Arithmetic() {}
}

class Adder extends Arithmetic {
    Adder() {}
    
    int add(int a, int b) {
        return a + b;
    }
}

Inheritance in java

it is used to define relationship between two class, 
which a child class occurs all the properties and
  behaviours of a parent class. 
Provides code reusability.
Ex: in my framework I have a TestBase 
class which I store 
all my reusable code and methods.
  My test execution classes and 
elements classes will extend the 
TestBase in order to reuse the code.
