1) Create an arraylist and add 10 mobilephone objects with different properties. For Example different os, different brand etc. 2) From 3 to all other sections create different for loops to print and place --- mark to seperate the results of the operations. 3) Call all mobilephone object's toString method. (In this case toString method of Computer is inherited) 4) Call all mobilephone object's camera object's toString method. 5) Call all mobilephone object's camera object's brand property. 6) Call all mobilephone object's os property. 7) Call all mobilephone object's makeCall method. 8) Call all mobilephone object's play Video method. 9) Call all mobilephone object's pause Video method.

OOPs
In today's technology-driven world, computer programming skills are in high demand. The object-oriented programming (OOP) approach is very much useful while designing and maintaining software programs. Object-oriented programming (OOP) is a basic programming paradigm that almost every developer has used at some stage in their career.
Constructor
The easiest way to think of a constructor in object-oriented programming (OOP) languages is:
Question
can you write the solution in java
![Problem: Create the classes and interfaces on the UML class diagram.
<<<Interface>>>>
VideoPlayer
+ play Video (uri: String): void
pauseVideo(url String): void
App1
+ main(args:String[]):void
-mobilephones: ArrayList<MobilePhone --Use> -camera: Camera
Extends

+ bus: Bus
App2
-os: String
+ toString():void
1) Create an arraylist and add 10 mobilephone objects with different properties. For
Example different os, different brand etc.
+ main(args String[]):void
Computer
+ make Call(phonenumber:String): void
2) From 3 to all other sections create different for loops to print and place --- mark to
seperate the results of the operations.
3) Call all mobilephone object's toString method. (In this case toString method of
Computer is inherited)
4) Call all mobilephone object's camera object's toString method.
5) Call all mobilephone object's camera object's brand property.
6) Call all mobilephone object's os property.
7) Call all mobilephone object's makeCall method.
8) Call all mobilephone object's play Video method.
9) Call all mobilephone object's pause Video method.
Extra Question:
