I need help with this method in java. Just give it your best shot.
Employee {abstract} implements Comparable<Employee>
- String firstName
- String lastName
- char middleInitial
- boolean fulltime
- char gender
- int employeeNum
<<constructor>> Employee (fn : String, ln : String, m : char, g : char, empNum : int, ft : boolean ) throws InvalidEmployeeNumberException

+ resetWeek() {abstract}
+ compareTo(Employee e) : int
setEmployeeNumber(int empNum)
Instead of the setEmployeeNumber reprompting for a valid Employee Number we will use an Exception to inform the calling method it was an invalid Employee number. If an invalid Employee number is passed to the method throw a new InvalidEmployeeNumberException, passing the invalid number to its constructor.
Constructor
The constructor calls upon setEmployeeNumber which now throws the checked Exception of InvalidEmployeeNumber, it should not be caught, rather declared such that the constructor passes the Exception on to the calling method.
public int compareTo(Employee e)
By implementing the Comparable interface, Employee becomes what is known as a Comparable type. All Comparable types have the compareTo() method which determines the logical ordering of instances of the class. This will be based on an Employee’s Employee Number. If the calling Employee’s number is greater than the passed Employee’s number return 1, if it is less than return -1, if they are equal return 0. The use of this will be necessary for the ArrayList’s sort.

Solution
Need more information to write below methods
+ calculateWeeklyPay() : double {abstract}
+ annualRaise() {abstract}
+ holidayBonus() : double {abstract}
+ resetWeek() {abstract}
ping me if you need any furthur help
