Fractions
I need help with an assignment I have for school. I'm a sophomore in high school in Computer Science 1. We use Eclipse (Java) for our programs.
Here is the PDF for the assignment:
Classes
I uploaded my Classes project too. Here is what I have so far The class is called "FractionClass" and "FractionClassTester".

PLEASE HELP ME!

Re: Fractions
Do you have any specific questions about your assignment?
Please post your code and any questions about problems you are having.
Post everything here on the forum. No links.

Assignment:
You will create a class to represent fractions. The requirements below will establish how this class should be structured.
Part 1
* The class should store a numerator and denominator
(remember, data members should be private at this point in your programs) * The class should have both a default and non*default constructor
* Do not make any set() accessor methods
Part 2
* The class should have the following methods:
+ Fraction add(Fraction other)
+ Fraction subtract(Fraction other)
+ Fraction multiply(Fraction other)
+ Fraction divide(Fraction other)
+ print() : print the fraction to the screen [as a fraction]
** NOTE: none of the arithmetic methods should modify the values of either operand; they should simply return the result of the calculation.
Part 3
The main method in your tester class should have the following...
* 10 different Fraction variables initialized with different values
* 1 additional Fraction variable to store the result of the calculations
* 5 calls to the addition method, print out the results [not within the add method]
* 5 calls to the subtraction method, print out the results [not within the subtract method] * 5 calls to the multiply method, print out the results [not within the multiply method]
* 5 calls to the divide method, print out the results [not within the divide method]
For some reason my code won't open in Eclipse from my USB. But all I had was part one down.
 Update 
Please use the link for the Classes. I can't open it for some reason.

If you have questions about your code, post the code and your questions.
