Description:
NEED HELP!!! I need someone to help me with some Java homework regarding abstract classes. There are two parts. Need it done within 10 hours of acceptance!!!
Deliverables:
Part I:
Program will have 5 files:
Driver.java
Shape.java
MyPoint.java
MyCircle.java
MyRectangle.java
Define an abstract base class Shape that includes a protected class variable numShapes, a static method to get the numbers of shapes, and two abstract methods findArea() and printArea() to output the area of the shape. Derive subclass MyPoint from MyShape.
MyPoint has two constructors: the first one is default which initializes instance variables x,y to zero, the second one accepts two arguments. Also, increment numShapes in the two constructors. Derive subclasses from MyPoint for MyCircle, and MyRectangle. MyCirlce has two constructors: the first constructor is default which initializes radius to 1. Make sure to call a base class constructor to initialize the points (i.e. super(10,10)).
The second constructor accepts two arguments: a point and a radius. Also, implement two methods findArea() and printArea(). These two methods are overriding in base class MyShape. MyRectangle class is implementing similar to MyCircle class except in the default constructor call a base class constructor to initialize the points to 50,50 (i.e. super(50,50)). Implement toString() method for each class. Test the classes by selecting two objects of the derived classes, then invoking the printArea() method for each. Use the toString() methods in the derived classes.

--------------------------------------------------
Part II:
Program will have 6 files:
Driver.java
Employee.java
Boss.java
CommissionWorker.java
PieceWorker.java
HourlyWorker.java
Define an abstract base class Employee and use polymorphism to perform payroll calculations based on the type of an employee. The derived classes of Employee are Boss who gets paid a fixed weekly salary regardlass of the number of hours worked, CommissionWorker who gets a flat base salary plus a percentage of sales, PieceWorker who gets paid by the number of items produced, and HourlyWorker who gets paid by the hours and receives overtime pay.
An earnings method certainly applies generically to all employees. But the way each person's earnings are calculated depends on the class of the employee, and these classes are all derived from the base class Employee. So earnings is declared abstract in base class Employee and appropriate implementations of earnings are provided for each of the derived classes. Then, to calculate any employee's earnings, the program simply uses a base-class pointer (or reference) to that employee's object and invokes the earnings method.
