(Rational Numbers) Create a class called Rational for performing arithmetic with fractions. Write a program to test your class. Use integer variables to represent the private instance variables of the class the numerator and the denominator. Provide a constructor that enables an object of this class to be initialized when it's declared. The constructor should store the fraction in reduced form. The fraction sequivalent to 1/2 and would be stored in the object as 1 in the numerator and 2 in the denomina- tor. Provide a no-argument constructor with default values in case no initializers are provided. Pro- vide public methods that perform each of the following operations: a) Add two Rational numbers: The result of the addition should be stored in reduced form. Implement this as a static method. b) Subtract two Rational numbers: The result of the subtraction should be stored in re- duced form. Implement this as a static method. c) Multiply two Rational numbers: The result of the multiplication should be stored in reduced form. Implement this as a static method. d) Divide two Rational numbers: The result of the division should be stored in reduced form. Implement this as a static method. Return a String representation of a Rational number in the form a/b, where a is the numerator and b is the denominator. e) f) Return a String representation of a Rational number in floating-point format. (Con- sider providing formatting capabilities that enable the user of the class to specify the number of digits of precision to the right of the decimal point.)

Transcribed Image Text:(Rational Numbers) Create a class called Rational for performing arithmetic with fractions.
Write a program to test your class. Use integer variables to represent the private instance variables
of the class the numerator and the denominator. Provide a constructor that enables an object of
this class to be initialized when it's declared. The constructor should store the fraction in reduced
form. The fraction
is equivalent to 1/2 and would be stored in the object as 1 in the numerator and 2 in the denomina-
tor. Provide a no-argument constructor with default values in case no initializers are provided. Pro-
vide public methods that perform each of the following operations:
a) Add two Rational numbers: The result of the addition should be stored in reduced
form. Implement this as a static method.
b) Subtract two Rational numbers: The result of the subtraction should be stored in re-
duced form. Implement this as a static method.
c)
Multiply two Rational numbers: The result of the multiplication should be stored in
reduced form. Implement this as a static method.
d) Divide two Rational numbers: The result of the division should be stored in reduced
form. Implement this as a static method.
e) Return a String representation of a Rational number in the form a/b, where a is the
numerator and b is the denominator.
f) Return a String representation of a Rational number in floating-point format. (Con-
