在本文中，我们将了解如何实现多重继承。 Java不支持多重继承。这意味着一个类不能扩展多个类，但我们仍然可以使用关键字“extends”来实现结果。

算法

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

示例 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();
   }
}

输出

Connection to database established successfully
Connection to backend established successfully
Connection to frontend established successfully

示例 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();
   }
}

输出

I am trying this food
I am trying this route
