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
的中文翻译为：
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();
}
}
登录后复制
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
