Instructions:
You must submit two separate copies (one Word file and one PDF file)using the Assignment Template on Blackboard via the allocated folder. These files must not be in compressed format.
It is your responsibility to check and make sure that you have uploaded both the correct files.
Zero mark will be given if you try to bypass the SafeAssign (e.g. misspell words, remove spaces between words, hide characters, use different character sets, convert text into imageor languages other than English or any kind of manipulation).
Email submission will not be accepted.
You are advised to make your work clear and well-presented. This includes filling your information on the cover page.
You must use this template, failing which will result in zero mark.
You MUST show all your work, and text must not be converted into an image, unless specified otherwise by the question.
Late submission will result in ZERO mark.
The work should be your own, copying from students or other resources will result in ZERO mark.
Use Times New Roman font for all your answers.

Learning Outcome(s):
Develop a program based on specification using programming language elements including syntax, data types, conditional statement, control structures, procedures, arrays, objects and classes
Question One
Write a java program that:
Create an abstract class named Shape that contains three integers length, breadth, radius and an empty method named printArea().
Provide three classes named Rectangle, Triangle and Circle such that each one of the classes extends the class Shape.
Each one of the classes contains only the method printArea() that read the requested values and prints the area of the given shape.
Provide a class Main that create a rectangle, a triangle and a cercle then print their respective areas.
Note: you should Include the screenshot of the program output as a part of your answer. Otherwise, zero marks will be awarded.

Learning Outcome(s):
Develop a program based on specification using programming language elements including syntax, data types, conditional statement, control structures, procedures, arrays, objects and classes
Question Two
Create a class called Invoice that a hardware store might use to represent an invoice for an item sold at the store.
An Invoice should include four information as instance variables: a part number (type String), a part description (type String), a quantity of the item being purchased (type int) and a price per item (double).
Your class should have a constructor that initializes the four instance variables. Provide a set and a get method for each instance variable.
In addition, provide a method named getInvoiceAmount that calculates the invoice amount (i.e., multiplies the quantity by the price per item), then returns the amount as a double value. If the quantity is not positive, it should be set to 0. If the price per item is not positive, it should be set to 0.0.
Write a testerclass named InvoiceTest that demonstrates class Invoice’s capabilities by creating two invoices then changing and printing their characteristics.
Note: you should Include the screenshot of the program output as a part of your answer. Otherwise, zero marks will be awarded.

Question Three
Write a complete Java program that do the following:
Read your student’s ID number, store it in an array named myStudentNO and print it.
find the number of even and odd integers in myStudentNO array
Note: Your program output should look as shown below
Note: you should Include the screenshot of the program output as a part of your answer and you should enter your student id number. Otherwise zero marks will be awarded.
