Create a java program named RationalNumber with the following specifications:

Data fields: int numerator, int denominator

Constructor: public RationalNumber(int n, int d)

Instance methods:

a) public RationalNumber add(RationalNumber r) //Adds the rational number in the object containing the called method and the rational number in the r object. Returns a new RationalNumber object that contains the sum

b) public RationalNumber multiply(RationalNumber r) // Multiplies the rational number in the object containing the called method and the rational number in the r object. Returns a new RationalNumber object that contains the product

c) Public void reduce() //Reduces the rational number to lowest terms. Does not create a new object

d) Public String toString() //Returns a string representing the value of the rational number. The string returned should include the slash character between the numerator and the denominator.

e) Test with 3/7 and 7/3
