Constructor Detail

Fraction

public Fraction(int numeratorIn, int denominatorIn) throws ZeroDenominatorException Fraction constructor, accepts numerator and denominator values. Ensures denominator is not 0 by calling upon setDenominator which throws ZeroDenominatorException, rethrows this Exceptions.

Parameters: numeratorIn - Numerator of Fraction. denominatorIn - Denominator of Fraction. Throws: ZeroDenominatorException - Rethrown Exception from setDenominator.

Method Detail

setNumerator

public void setNumerator(int numeratorIn) Sets the numerator of the Fraction.

Parameters: numeratorIn - Incoming value of the numerator.

setDenominator

public void setDenominator(int denominatorIn) throws ZeroDenominatorException Sets the denominator of the Fraction.

Parameters: denominatorIn - Incoming value of the denominator. Throws: ZeroDenominatorException - Throws ZeroDenominator Exception if denominatorIn is 0.

getDecimal

public double getDecimal() Returns the decimal value of this Fraction.

Returns: Decimal value of the Fraction by dividing numerator by denominator.

equals

public boolean equals(java.lang.Object o2)

Overrides: equals in class java.lang.Object

toString

public java.lang.String toString() Creates and returns common representation of Fraction: numerator / denominator.

Overrides: toString in class java.lang.Object Returns: Fraction as a String.
