Payroll System - Phase 2

***Include javadoc comments for all new methods added to the project.***

Company class:

Modification 1: In the constructor, make a copy of the departments parameter before using it to set the listOfDepartments instance variable.

Modification 2: In the setListOfDepartments method, make a copy of the departments parameter before using it to set the listOfDepartments instance variable.

Modification 3: In the getListOfDepartments method, return a copy of the listOfDepartments instance variable.

Modification 4: Write a method called addDepartment, which doesnt return a value and has 1 parameter of type Department. It adds a copy of the dept parameter to the listOfDepartments instance variable.

The following is the method signature:

Modification 5: Write a method called addEmployeeToDepartment, which doesnt return a value and has 2 parameters, the first is of type int, and the second of type Employee. This method iterates through all the elements in the listOfDepartments instance variable looking for a Department whose departmentID is equal to the int value passed as the first argument. If it finds it, it adds to it a copy of the Employee object passed as the second argument.

Below is the method header:

Modification 6: Write a method called setDepartmentManager, which doesnt return a value and has 2 parameters, the first is of type int, and the second of type Manager. This method iterates through all the elements in the listOfDepartments instance variable looking for a Department whose departmentID is equal to the int value passed as the first argument. If it finds it, it calls the setDepartmentManager method on that object passing the manObject parameter.
