Question

Write a class called Employee based off of the following form:

First Name:

Last Name:

EmployeeID:

Email:

The first name, last name, and employee id should be stored in fields. The email should be computed via a method.

The email should be the first three letters of the first name followed by the first five letters of the last name followed by the last 2 digits of the 5 digit employee id followed by @hotmail.com.

The fields should all be private and each field should have get and set methods.

Next, write a Java application that instantiates three different Employee objects. Set the first name, last name, and id fields with data of your choosing. Call the method to set the email address for each employee. Finally, display the contents of all the fields of the three Employee objects.

Name the first class Employee with your last name added to the end of Employee.

Name the second class EmployeeTest with your last name at the end.
