Question

I would like help and there are three different classes in the coding..
14.11 Prog11 Inheritance(PayrollOvertime) Create three files to submit: • Payroll class.java -Base class definition • PayrollOvertime.jave - Derived class definition • ClientClass.java - contains main() method Implement the two user define classes with the following specifications: Payroll class (the base class) (4 pts) • 5 data fields(protected) o String name - Initialized in default constructor to "John Doe" o int ID - Initialized in default constructor to 9999 o doulbe payRate - Initialized in default constructor to 15.0 o doulbe hrWorked - Initialized in default constructor to 40 ostatic int data field named nOfObjs for tracking the number of employees, (initialized to 0 and updated nofobjs++ in the constructors) • 2 constructors (public) o Default constructor (make sure to update the nOfObjs member) O A constructor that accepts the employee's name, ID, and pay rate as arguments. These values should be assigned to the object's name, ID, and payRate fields, also update the nofobjs member • 8 public member methods (mutators, accessors, and other) o getNofObjts( o getName o getIDO osetPayRate(& getPayRate() o setHrWorked & getHrWorked o Amethod named grossPay that returns employee's gross pay (=hrWorked * payRate) PayrollOvertime class (the derived class) (4 pts) • 2 private fields o double overtimePayRate-Initialized in default constructor to 22.5 o double overtimeHrWorked - Initialized in default constructor to O • 2 constructors (public) (2 pts) o Default constructor (use super to invoke the Payroll constructor) O A constructor that accepts the employee's name, ID, and pay rate, over time pay rate as arguments. These values should be assigned to the object's name, ID, payRate, and overtimePayRate fields. (use super() to invoke the Payroll constructor) • 5 public member methods (mutators, accessors, and other) o getOvertimePayRate) & setOvertime HrWorked (double) o getOvertime HrWorked & setOvertimePayRate(double) o Override the grossPay method of Payroll class, that returns employee's gross pay (hrWorked * payRate+ overtimePay Rate *overtimeHrWorked) ClientClass (2 pts) In main() method, create two PayrollOvertime objects (one use the info inputted by the user and the other use the default constructor), and print the info for each employee
