Answer the following statement true (T) or false (F)
Write and fully test a class that represents rational numbers. A rational number can be represented as the ratio of two integer values, a and b, where b is not zero. The class has attributes for the numerator and denominator of this ratio. The ratio should always be stored in its simplest form. That is, any common factor of a and b should be removed. For example, the rational number 40/12 should be stored as 10/3.
The class has the following constructors and methods: • A default constructor that sets the rational number to 0/1. • A constructor that has parameters for the numerator and denominator, and converts the resulting ratio to simplified form. • simplify—a private method that converts the rational number to simplified form. • getGCD(x, y)—a private static method that returns the largest common factor of the two positive integers x and y, that is, their greatest common divisor. For example, the greatest common divisor of 40 and 12 is 4. • value—returns the rational number as a double value. • toString—returns the rational number as a string in the form a/b. This project demonstrates a class that uses a couple private methods to accomplish some small tasks.
