Classes and Objects; Object vs. reference, comparing objects, copying objects.

    a. Create a new project Lab08. Download class ​Project from Lab07 and add to Lab08 project. You should not make any changes to this class.

    b. Create a class ​Department​:
        ◦ Instance Data Members:

            ▪ deptName​: stores the name of the department.

            ▪ deptCode​: stores the code of the department.

        ◦ Methods:

            ▪ Constructor:

                • Initializes the department name and department code using the ones passed as parameters.

            ▪ Accessor / Mutator methods for:

                • deptName, deptCode.

            ▪ Other methods:

                • equals​(): instance method that takes a Department as a parameter, and returns true if the target department and the one passed as a parameter are the same, false if not.

                • toString​(): returns a String representation of a department. See sample output for format details.

    c. Create a class ​DepartmentTest​.

Write a main method to create and compare Department instances using == and .equals.

        ◦ Create two references to a single Department instance,

        ◦ Create two references to two individual instances with different properties,

        ◦ Create two references to two individual objects with identical properties.

You should run your code without .​equals implementation in your ​Department class (comment your .​equals method in ​Department class). Do you get the same results with == and .equals? Can you explain why?

Now write .​equals method in your ​Department class. Two department instances are considered the same if they have the same department name and the same department code. Run your comparison tests again and explain whether there are any changes in the output.
    d. Create a class ​Employee:
        ◦ Constant data member:

                • WORKING_DAYS: there are 270 working days per year.

            ▪ Instance Data Members:

                    ◦ employeeName​: stores the name of the employee.

                    ◦ dailyRate​: stores the double daily pay rate of the employee.
                    ◦ department​: stores the department of the employee.
                    ◦ project​: stores the project the employee has been assigned to.

            ▪ Methods:

                    ◦ Constructor:

                        ▪ Initializes the employee name, rate and project using the ones passed as parameters. Also takes the department name and code as parameters, initializes a new department using the ones passed as a parameter.

                    ◦ Constructor:

                        ▪ Copy constructor: creates a new ​Employee object using the data from the ​Employee passed as a parameter. The new employee will be assigned to the same project.

                    ◦ Accessor / Mutator methods for:

                        ▪ employeeName, dailyRate, department, project.

                    ◦ Other methods:

                        ▪ calculateYearlySalary​(): Calculates and returns yearly salary.

                        ▪ toString​(): returns a String representation of an Employee. See sample output for format details.

    e. Create and application, EmployeeApp that does the following:

                    ◦ Create a Project.

                    ◦ Create 3 Employees who are assigned to the project.

                    ◦ Create a new Employee that is a copy of the first.

                    ◦ Display the 4 Employees.

                    ◦ Compare the Department of all Employees, and display Employees with matching Departments.
