The calculatePay() method from the staff class will be implemented in the subclass to calculate the employee's pay. The pay for Parttimer is based on the skill level of staff as shown in Table 1, which is the payment can be calculated by multiplying hours worked with the pay rate per hour. The method toString() will return the information of Parttimer object. The PartTimer class implements compareTo () method from java.lang.Comparable interface to compare the payment of two objects. Then write a test program that creates two PartTimer objects using parameterized constructor with any values assigned to their data fields. Then display all the information includes the comparison result of the payment for these two objects
