Please answer the question in Java. Thank you so much!

1. Part One: Define a class for rational numbers. A rational number is a number that can be represented as the quotient of two integers. For example, 1/2, 3/4, 64/2, and so forth are all rational numbers. (By 1/2 and so forth, we mean the everyday meaning of the fraction, not the integer division this expression would produce in a Java program.) Represent rational numbers as two values of type int, one for the numerator and one for the denominator. Your class should have two instance variables of type int. Call the class Rational . Include a constructor with two arguments that can be used to set the instance variables of an object to any values. Also include a constructor that has only a single parameter of type int; call this single parameter wholeNumber and dehne the constructor so that the object will be initialized to the rational number wholeNumber/1. Also include a no-argument constructor that initializes an object to O (that is, to 0/1). Note that the numerator, the denominator, or both may contain a minus sign. Define methods for addition, subtraction multiplication, and division of objects of your class Rational . These methods should be static methods that each have two parameters of type Rational and return a value of type Rational. For example, Rational.add(r1, r2) will return the result of adding the two rational numbers (two objects of the class Rational, r1 and r2). Define accessor and mutator methods as well as the methods equals and toString. You should include a method to normalize the sign of the rational number so that the denominator is positive and the numerator is either positive or negative. For example, after normalization, 4/-8 would be represented the same as -4/8. Also write a test program to test your class
