YOUR JOB:

Implement the following methods in the Fraction class:

public void add(Fraction other)

public void subtract(Fraction other)

public void multiply(Fraction other)

public int getNumerator()

public int getDenominator()

public void setNumerator(int x)

public void setDenominator(int x)

public String toString()

Use the FractionTester file to test as you go along.

HINTS:

Note that

public void add(Fraction other)

public void subtract(Fraction other)

public void multiply(Fraction other)

are void methods. They do not return anything. These methods should not create a new Fraction and return it.

Instead, these methods should modify the instance variables to be added, subtracted, or multiplied by the Fraction other.

For example, if you had the following code in your FractionTester class:

Fraction first = new Fraction(1, 2);

Fraction second = new Fraction(1, 3);

System.out.println();

System.out.println("BEFORE:");

System.out.println("first: " + first);

System.out.println("second: " + second);

first.multiply(second);

System.out.println("AFTER:");

System.out.println("first: " + first);

System.out.println("second: " + second);

Running should print out:

BEFORE:

first: 1 / 2

second: 1 / 3

AFTER:

first: 1 / 6

second: 1 / 3

The Fraction first was modified by being multiplied by the Fraction second. first was affected, second was not. 1/2 became 1/6 because it was multiplied by 1/3.
