Question
Can you write the required in java by using the methods
![Problem: Create the classes on the UML class diagram. Set Inheritance relationship between
the classes.
Application1
-media: Student
-song: Song
-movie: Movie
+ main(args[]: String): void
Song
-artist: String
+ getinfo():void
Use
Media
- id: int
~ duration: int
-size: double
+ getid(): int
+ setid(id:int): void
toString(): String
Extends
12
Extends
Movie
- producer: String
printDetail(): void
1) Apply encapsulation for id.
2) Create a media object and call toString method. Create song object as Media
object and downcast it to Song object and call getInfo method. Create movie
object as Media object and downcast it to Movie object and call printDetail
method.(you can print sth to the console for Example to be sure about if it is
working or not)
3) Create 5 media objects, 1 of them media,2 of them Song and 2 other Movie objects
and then call toString method using for loop to see the properties of the objects.](https://content.bartleby.com/qna-images/question/5271313a-5a1f-4d07-82a4-8e8f0bce0b42/b1b1db2e-1a59-4a08-b096-7ae24d4b1eb0/amuaucm_processed.png)
