Java Program to Implement Multiple Inheritance
In this article, we will understand how to implement multiple inheritance. Java does not support multiple inheritance. This means that a class cannot extend more than one class, but we can still achieve the result using the keyword 'extends'.
Algorithm
Step 1 – START Step 2 – Declare three classes namely Server, connection and my_test Step 3 – Relate the classes with each other using 'extends' keyword Step-4 – Call the objects of each class from a main function. Step 5 – STOP
Example 1
class Server{ void my_frontend(){ System.out.println("Connection to frontend established successfully");} } class Java extends Server{ void my_backend(){ System.out.println("Connection to backend established successfully"); } } class connection extends Java{ void my_database(){ System.out.println("Connection to database established successfully"); } } public class my_test{ public static void main(String args[]){ connection my_connection=new connection(); my_connection.my_database(); my_connection.my_backend(); my_connection.my_frontend(); } }
Output
Connection to database established successfully Connection to backend established successfully Connection to frontend established successfully
Example 2
interface My_restaurents { void eat(); } interface My_journey { void travel(); } class Holiday implements My_restaurents, My_journey { public void eat() { System.out.println("I am trying this food"); } public void travel() { System.out.println("I am trying this route"); } } public class My_trip { public static void main(String args[]) { Holiday my_schedule = new Holiday(); my_schedule.eat(); my_schedule.travel(); } }
Output
I am trying this food I am trying this route
