A Fraction Class

Assignment

You are to write a simple Fraction class that implements simple fractions, with a numerator and denominator. Denominators must be positive (not negative, not 0). Numerators can be positive, negative or 0. Keep these in mind with your constructors and other methods.

Your Fraction class should provide the following constructors

• Fraction() - create a new fraction with a reasonable default value (possibly 0 for the numerator and 1 for the denominator.
• Fraction(int num, int denom) - create a new fraction with numerator num and denominator denom.
• Fraction(int val) - create a new fraction with value val (that is, numerator val and denominator 1).

Your Fraction class should provide the following methods:

• void setValue(int num, int denom) - set the value of the fraction.
• void setValue(Fraction f) - set the value of the fraction.
• int getNumerator() - get the numerator.
• int getDenominator() - get the denominator.
• double toDouble() - convert the fraction to a decimal value.
• String toString() - convert the fraction to a string of the form num/denom.
• void showMixed() – display the fraction in mixed form if numerator is greater than the denominator. Otherwise, show as normal fraction.
• Fraction reduce() – return a reduced form of the current fraction. This should not modify the value of the current fraction.
• Fraction add(Fraction f) - add a fraction to the current fraction. This should not modify the value of the current fraction.
• Fraction multiply(Fraction f) - multiply the current fraction by another fraction. This should not modify the value of the current fraction.
• Fraction subtract(Fraction f) - subtract a fraction from the current fraction. This should not modify the value of the current fraction.
• Fraction divide(Fraction f) - divide the value of the current fraction by f. This should not modify the value of the current fraction.
• Fraction add(int i) - an an integer to the current fraction This should not modify the value of the current fraction.
