Write a class called RationalNumber that represents a fraction with an integer numerator and denominator. A RationalNumber object should have the following methods:
public RationalNumber(int numerator, int denominator)

Constructs a new rational number to represent the ratio (numerator/denominator). The denominator cannot be 0, so throw an IllegalArgumentException if 0 is passed.
public RationalNumber()

Constructs a new rational number to represent the ratio (0/1).
public int getDenominator()

Returns this rational number's denominator value; for example, if the ratio is (3/5), returns 5.
public int getNumerator() Returns this rational number's numerator value; for example, if the ratio is (3/5), returns 3. public String toString()

Returns a String representation of this rational number, such as "3/5". You may wish to omit denominators of 1, returning "4" instead of "4/1".

An extra challenge would be to maintain your RationalNumber objects in reduced form, avoiding rational numbers such as 3/6 in favor of 1/2, or avoiding 2/-3 in favor of -2/3. Another possible extra feature would be methods to add, subtract, multiply, and divide two rational numbers.
