Answer to Question #200840 in Java | JSP | JSF for Thabby

Question

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

Answer 1
