  Quiz

  1. Design a class hierarchy rooted in the class Employee that includes subclasses for HourlyEmployee and SalaryEmployee. The attributes shared in common by these classes include the name, and job title of the employee, plus the accessor and mutator methods needed by those attributes. The salaried employees need an attribute for weekly salary, and the corresponding methods for accessing and changing this variable. The hourly employees should have a pay rate and an hours worked variable. There should be an abstract method called calculateWeeklyPay(), defined abstractly in the superclass and implemented in the subclasses. The salaried worker’s pay is just the weekly salary. Pay for an hourly employee is simply hours worked times pay rate.

        2..Write a Java program to create a class Vehicle with a method called speedUp(). Create two subclasses Car and Bicycle. Override the speedUp() method in each subclass to increase the vehicle's speed differently
