Defining a rational class. Simple but i cant figure it out to save my life

Define 3 constructors and a toString method, setters, and getters

Define arithmetic methods for add, subtract, multiply, divide, and negate. The negate method will return the negative of the calling Rational object – return new Rational (-num,denom);

Define logical methods for equals, notEquals, lessThan, lessThanOrEqual, greaterThan, and greaterThanOrEqual.

All negative values should be represented with the negative sign in the numerator – do this in the setDenom method and call it in the constructor.

Extra Credit: add a greatestCommonDivisor method to reduce a Rational number to its lowest terms. If you write this method, add the reduced values to your output. For example:

½ + ¾ = 10/8 reduced to 5/4

Run three times with the following data: (read in the data then use one of the constructors or the setter methods to fill objects with data)

Input 1: 1/2, 3/4 - entered as 1 2 3 4

Input 2: 1/2, 5/10 – entered as 1 2 5 10

Input 3: 3/-5, 2 – entered as 3 -5 2 1

Output (using the first set of numbers):

Rational 1 –>1/2 reduced to _______

Rational 2 -> 3/4 reduced to_______

½ + ¾ ______ reduced to_______

½ - ¾ ______ reduced to_______

½ * ¾ ______ reduced to_______

½ / ¾ ______ reduced to_______

- ½ ______ reduced to_______

½ == ¾ ______ print true or false

½ != ¾ ________ print true or false

½ > ¾ ______ print true or false

½ >= ¾ ______ print true or false

½ < ¾ ______ print true or false

½ <= ¾ ______ print true or false

Dumping homework assignments is unproductive at best. Please see the link in my signature entitled getting help, as well as the following:

Did you read the links I provided? Without knowing any context - from whether you know how to make a hello world program to whether you know loops to whether you know object oriented programming - we will have a hard time pointing you in the right direction. Break the problem down, and concentrate on one requirement at a time...ask a specific question about that requirement.
