Description
This assignment lets you practice basic Functional Programming and Lambda Expressions in
Java.
In this assignment, you will be adding some code to the workshop 2 (shapes) as follows:
Task 4: Define a functional interface to calculate the area of a shape. Create an object of that
interface in each of the Circle, Square, Rectangle classes, using lambda expressions.
Print all the shapes and their perimeters polymorphically, as you did in task 1 (don’t forget that
you are using just one Shape array) but in cases that the shape being printed is an object of
these classes (i.e. Circle, Square, Rectangle), print their areas (using the above
mentioned objects you created) as well.
Marking Criteria and Tasks:
Please note that you should:
a- have appropriate indentation.
b- have proper file structures and modularization.
c- follow Java naming conventions.
d- document all the classes properly.
e- not have debug/useless code and/or file(s) left in assignment.
f- have good intra and/or inter class designs.
in your code!
• Task: Developing and running the desired solution: (you should submit your source
code – just individual .java files, and screenshots which demonstrate the way
your code runs): 5 marks.
Deliverables and Important Notes:
• You are supposed to submit your solution online on Bb by the end of the day on
Monday, 13th of June, 2020.)
• Please note that you would be allowed to submit just once, so please be super
careful and double check before you hit submit.
• There would be a 20% penalty for each day (or part of it,) in case you submit
late!
• Remember that you are encouraged to talk to each other, to the instructor, or to
anyone else about any of the assignments, but the final solution may not be copied
from any sources.
