Question

With Java Language:

In this assignment, you are to create a class named Payroll. In the class, you are to have the following data members: name: String (5 pts) .İd: String (5 pts) hours: int (5 pts) rate: double (5 pts) private members (5 pts) You are to create no-arg and parameterized constructors and the appropriate setters(accessors) and getters (mutators). (20 pts) The class definition should also handle the following exceptions: An employee name should not be empty, otherwise an exception should be thrown. (10 pts) An employee id should have the form LLNNNN. If that form is not received, an exception should be thrown. (10 pts) thrown otherwise. (10 pts) thrown otherwise. (10 pts) An employee's hours should neither be negative nor greater than 84. An exception should be An employee's pay rate should neither be negative nor greater than 25.00. An exception should be Demonstrate this class in a program (separate class or in the same class). (5 pts) The exception messages should be appropriate to the specific exception that has occurred. (5 pts) Create a package payroll for the project.(5 pts)
