Inheritance can be defined as the process where one class acquires the properties (methods and fields) of another. With the use of inheritance, the information is made manageable in a hierarchical order.
The class which inherits the properties of other is known as a subclass (derived class, child class) and the class whose properties are inherited is known as superclass (base class, parent class).
class Calculation { int z; public void addition(int x, int y) { z = x + y; System.out.println("The sum of the given numbers:"+z); } public void Subtraction(int x, int y) { z = x - y; System.out.println("The difference between the given numbers:"+z); } } public class My_Calculation extends Calculation { public void multiplication(int x, int y) { z = x * y; System.out.println("The product of the given numbers:"+z); } public static void main(String args[]) { int a = 20, b = 10; My_Calculation demo = new My_Calculation(); demo.addition(a, b); demo.Subtraction(a, b); demo.multiplication(a, b); } }
Compile and execute the above code as shown below.
javac My_Calculation.java java My_Calculation
After executing the program, it will produce the following result −
The sum of the given numbers:30 The difference between the given numbers:10 The product of the given numbers:200
