Write an application in Java that will simulate the contacts
apps. The text below shows the details of the application. Just
like in real contacts apps, a number must be unique to a contact.
Assume that user will not enter invalid inputs.
Create a java application in which the system will run following
tasks:
user will enter 1 to 5
The application will run these:
