Answer to Question #204345 in Java | JSP | JSF for Tshego

Question

Question 2 (Marks: 20)

The organisation you work for has asked you to create an interactive application that will assist 

with the allocation of employees to a cell phone network provider and phone number generation. 

You are required to prompt a user for three employee names which will randomly assign the 

employee to either the Vodacom, MTN or Cell C network. The employees also require a randomly 

generated phone number. The start of each phone number will begin with the following, 

depending on the network provider:

NETWORK PROVIDER START

Vodacom 072

MTN 083

Cell C 084

The remaining numbers of the phone number must be randomly generated.
