Programming Project 1

There is no grace period for this project. Please submit by the deadline.

You learned that computers follow instructions faithfully and they never get tired of repeating

the same thing over and over. You plan to write a simple program Calculator.java to see for yourself.

After bragging a bit, the program asks the user to enter 2 numbers. After receiving and storing

those it asks the user to enter one of the operations +, -, *, or /. The program then performs that

operation on the two numbers and displays the output to the user (if the user enters an operation

different from the four operations above, the program notifies the user that it does not know that

operation). It then brags some more and asks the user if they want to play again. If the user enters Y or

y, the game starts over. Otherwise the program prints Bye bye and terminates.

A few sample runs of the program are shown below:

----------------------------- Run 1 --------------------------------- Hi, I am really good at math! Put me to the test. Please enter two numbers and then press Enter: 3 6 Please enter one of the operations +, -, * or / and press Enter: + 3 + 6 = 9 I'm great at addition! Play again [Y/N]?: N Bye bye!

----------------------------- Run 2 --------------------------------- Hi, I am really good at math! Put me to the test. Please enter two numbers and then press Enter: 2.7 0.82 Please enter one of the operations +, -, * or / and press Enter: - 2.7 - 0.82 = 1.88 I'm great at subtraction! Play again [Y/N]?: N Bye bye!

----------------------------- Run 3 --------------------------------- Hi, I am really good at math! Put me to the test. Please enter two numbers and then press Enter: 1 3 Please enter one of the operations +, -, * or / and press Enter: / 1 / 3 = 0.333333 I'm great at division! Play again [Y/N]?: Y Hi, I am really good at math! Put me to the test. Please enter two numbers and then press Enter: 3.14 2 Please enter one of the operations +, -, * or / and press Enter: * 3.14 * 2 = 6.28 I'm great at multiplication! Play again [Y/N]?: y Hi, I am really good at math! Put me to the test. Please enter two numbers and then press Enter: 2 3 Please enter one of the operations +, -, * or / and press Enter: $ I can compute really well, but what you entered is not one of the operations I know ... Play again [Y/N]?: N Bye bye!

Hints:

– This program is really simple and many of you will find it trivial. The goal of the assignment is for students to get familiar with their development tool, basic program design and the basic

structure of a program.

– The program uses 4 variables, two for the numeric values, one for the operation, and one for playing again or terminating. What type should these variables be?

– To be able to perform a different computation based on the operation entered the program will need to make a choice.

– Write the program initially without the “Play again?” functionality. Once you have that, wrap a loop around it to allow for repeated games.

– Ask for help if you get stuck

Deliverables:

You should submit a zip file named project1_first_last.zip (where first and last are your first

and last name) containing ONLY the files below.

Calculator.java

report.txt (a short text file saying “I have tested this program and it has no

issues” and a sample output from your program (like the

examples given above but with your own 2 numbers and

operation). If your program has some problem/bug that you are

aware of, please mention that in the report.)

How you get points:

Functionally correct solution 70 points

Good program structure 20 points

Good variable names, style and comments 10 points

How you lose points:

– You do not submit a report file. – Your code does not follow the posted style guidelines. – Your code does not contain some appropriate comments.
