Inheritance in Java

Java Programming Java8Java Technologies Object Oriented Programming

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).

Example

 Live Demo 

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 − 

Output 

The sum of the given numbers:30
The difference between the given numbers:10
The product of the given numbers:200
