ElementCollection to implement one to many mapping in Spring Boot application

Default methods are new feature in java8 which allows to provide implementation for methods in interfaces declarations.

public interface Food{

default void menuItems(){


// write the code of this method implementation
 System.out.println("I am menu");

}

} // End of Food Class


public class Hotel implements Food{

// remember there is no overriding of method menuItems() of Food interface
public void hotelDetails(){

 System.out.println("I am Hotel Grand");
}

} // End of Hotel Class


public class Test
{

public static void main(String a[]){

Hotel h= new Hotel();
h.hotelDetails();
h.menuItems();

}
} // end of Test Class
