Constructor Detail

ProperFraction

public ProperFraction(int wholeNumber,
                      int numerator,
                      int denominator)

This constructor should take three integers and make a ProperFraction object Fractions cannot have a denominator of 0! If the denominator is 0, set the whole number to 0, the numerator to 0, and the denominator to 1.

Parameters:

wholeNumber - whole number for the fraction

numerator - numerator for the fraction

denominator - denominator for the fraction

ProperFraction

public ProperFraction(java.lang.String fraction)

This constructor should take a string such as "1 11/2" and make a ProperFraction object. Integer.parseInt(), .substring(), and .indexOf() will all be useful. Since this is a proper fraction, be sure to convert a fraction like "1 3/2" to "2 1/2". Fractions cannot have a denominator of 0! If the denominator is 0, set the whole number to 0, the numerator to 0, and the denominator to 1.

Parameters:

fraction - a string holding the numbers for a fraction in the form of "wholeNumber numerator/denominator"

Method Detail

makeImproper

public ImproperFraction makeImproper()

This method will take data from the ProperFraction object to produce an ImproperFraction

Returns:

a new ImproperFraction object

simplify

public void simplify()

This method will simplify a fraction. For example, 2/6 will be turned into 1/3 after running this method. A while loop and the % operator will both be useful here. (Don't forget to set this.numerator and this.denominator after finding the simplified fraction!) To simplify a fraction, both the numerator and denominator should be divided by the greatest common factor. Using a while loop, you can check all of the numbers. For an example of 4/6, you can start by checking 6, then 5, 4, 3, then 2. Since 4/2 and 6/2 are whole numbers, you can divide both the numerator and denominator to simplify the fraction. Once you find this greatest common factor, you can use "return" to end the method.
