Project 2 Inheritance and interface Task 1 Define a Rational class based on Number and Comparable A Rational number has a numerator and a denominator in the form a/b, where a is the numerator and b the denominator. For example, 1/5, 13/4, and 7/9 are rational numbers. Java provides data types for integers and floating- point numbers, but not for rational numbers. It is helpful to define a Rational class for representing rational numbers. Since rational numbers share many features with integers and floating-point numbers, and Number is the root for numeric wrapper classes, it is appropriate to define Rational as a subclass of Number. Since rational numbers are comparable, the Rational class should also implement the Comparable interface. Figure 1 illustrates the Rational class and its relationship to the Number class and the Comparable interface Write a program to test your Rational class, such as the additions, subtractions, multiplications, divisions, and numbers. comparisons for Rational Figure 1.
