2 Rational Implement a class to represent rational numbers. Each rational number consists of a numerator and a denominator, both of type int. Since each rational number has its own numerator and denominator, these must be instance variables. Furthermore, good object-oriented programming suggests that the visibility of the variables should be private. 3 Constructors The class Rational has two constructors. One of them has two formal parameters, which provide the initial values for both instance variables. The other constructor has a single parameter, which provides the initial value for the numerator: the denominator is assumed to be 1 4 getters Implement access methods that return the numerator and denominator of this rational, but no setter methods. An object that has no setter methods, and no other methods for
