LABORATORY EXERCISE$-10$

Problem: Create the classes and interfaces on the UML class diagram.

Create an arraylist and add $10$ mobilephone objects with different properties. For Example different os$,$ different brand etc.

From $3$ to all other sections create different for loops to print and place $---$ mark to seperate the results of the operations.
