Program Java melaksanakan pelbagai warisan

Dalam artikel ini, kita akan belajar cara melaksanakan pelbagai warisan. Java tidak menyokong pelbagai warisan. Ini bermakna kelas tidak boleh melanjutkan lebih daripada satu kelas, tetapi kita masih boleh menggunakan kata kunci "lanjutkan" untuk mencapai keputusan. Terjemahan bahasa Cina bagi

Algoritma

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

Contoh 1

ialah:

Contoh 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

Contoh 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
