Programming Assignment-2 
[To get the full credit of your programming assignment, find the problem solving steps and
documentation guidelines listed in ‘Programming Assignments’ section in D2L. You are supposed
to submit a zip file (don’t use winrar to zip) that should contain a documentation file like a docx
file and your codes with proper programming extensions like .java or .py. Make sure all of your
code is compliable or no runtime error.TA will not grade you if your code is not runnable and get
a zero]
1. Write an OOP code (A case study: Should be unique; If you are copying code from online you will
be caught) that has the following OOP features: inheritance(any), polymorphism (runtime and
compile time), abstraction and encapsulation (20 points)
2. Consider the following organigram (can be found in https://en.wikipedia.org/wiki/Mammal ) of
Mammalia family. (a: 5, b: 5, c: 10, d: 20, e:10) – (50 points)
a. Each of members
i. has
1. Legs (count)
2. Tails (yes/no)
3. Brain (yes/no)
4. Neurons (count)
5. Precision to understand (0.00 to 100.00%)
6. Birth date
7. Favorite foods
ii. can
1. Eat
2. Walk
3. Sleep
4. Give Birth
b. Think about perissodactyla, they can mate with carnivora members; can breed and
produce a new family called ‘Perivora’. Perivora animals supposed to give birth to a new
family ‘Periveron’. But by nature law no periveron member can be crated.
c. Create at least 5 animals from each family; Perviveron member cannot be produced.
d. Now you can do some creativity by changing the neurons, precision to understand, food
habits, but you can’t change the legs, brains, birth date. Change these features for at
least 20 animals and show how it was before and how it is now. From level 6 to
8(Considering Mammlia as level-1 and carnivora, cetartiodactyla are on level-8), animals
can run and hunt for their food. Change at least 10 animals’ running speed, hunting
process and hunting food type for those who are 6-8 level animals. Try changing at least
10 animals and show (reading from files; see next bullet) what they were and what they
are now.
e. All outcomes should be stored in a file. When you have created objects, their
information should be stored in files. After changing their behaviors and attributes, they
should also be stored in files. The term show mentioned in the previous sub-section
refers to reading the data from files and printing to the console.
3. Create a calculator class which can perform certain operations: addition, subtraction,
multiplication, division, and modulo. Now, add Java exception handling to your code by defining
two exception classes SyntaxError and RuntimeError. A SyntaxError exception
should be thrown when an illegal character is found, a closing ) is not found, or a = is not used
twice in an expression or an unwanted alphanumeric character inside the equation. A
RuntimeError exception should be thrown when a divide by zero occurs. The exceptions
should propagate the error to the main program which prints the diagnostics of the error. You
must handle these errors using Java exceptions and the message should be printed by a Java
exception handler in a catch clause. (30 points)
Compile, run, and test your program with at least these expressions:
Test Expression Correct Response
---------------- ---------------------
X = 1+ 2 + (3 Syntax error: ‘)’ expected
Y = 2 + 5 = 3 Syntax error: unexpected ‘=’
Y = 6*Z+5 Syntax error: more than one variable
Y 3+5+(1+6) Syntax error: ‘=’ expected
Z = (3+5)/0 Runtime error: Divide by zero occurred
A = 7*6/2 A = 21
