Create a class Rational that represents a rational number. It should have private attributes for

• The numerator (an integer)
• The denominator (an integer)
and the following methods:
• Rational(numerator, denominator)—a constructor for a rational number.
• Accessor methods getNumerator and getDenominator and mutator methods setNumerator and setDenominator for the numerator and the denominator. You should use an exception to guarantee that the denominator is never zero.

See the code in Rational.java.
