Write a class named Employee that has the following fields: name. The name field references 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 references a String object that holds the name of the department where the employee works. position. The position field references a String object that holds the employees job title.The class should have the following constructors: 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 appropriate mutator methods that store values in these fields and accessor methods that return the values in these fields. Once you have written the class, write a separate program that creates three Employee objects to hold the following data:Name ID NumberDepartment PositionSusan Meyers 47899 Accounting Vice PresidentMark Jones 39119 IT ProgrammerJoy Rogers 81774 Manufacturing Engineer The program should store this data in the three objects and then display the data for each employee on the screen.Deliverables:1.
