In Programming Challenge 1 of Chapter 3 you wrote an Employee class.

1. Employee Class

Write a class named Employee that has the following fields:

name. The name field is a String object that holds the employees name.

idNumber. The idNumber is an int variable that holds the employees ID number.

department. The department field is a String object that holds the name of the depart-

ment where the employee works.

position. The position field is a String object that holds the employees job title.

Write appropriate mutator methods that store values in these fields and accessor methods that return the values in these fields. Once you have the written the class, write a separate program that creates three Employee objects to hold the following data.

Name

ID Number

47899 39119 81774 

Department

Position

Add the following to the class:

6. Employee Class Modification

A constructor that accepts the following values as arguments and assigns them to the appropriate fields: employees name, employees ID number, department, and position.

A constructor that accepts the following values as arguments and assigns them to the appropriate fields: employees name and ID number. The department and position

fields should be assigned an empty string ("").

A no-arg constructor that assigns empty strings ("") to the name, department, and

position fields, and 0 to the idNumber field. Write a program that tests and demonstrates these constructors.
