Rational Number Class - Java Client Code For Testing

We are making a Rational Number class. After that we must create client code to test it out. The instructions-

•Create 3 instances of RationalNumber. Remember every time you say “new” you are creating an instance.
oOne of them should use the default constructor
oOne of them should use the constructor with one parameter
oOne of them should use the concstructor with two parameters.
•Print out the int and double value of each Rational Number
•Print out the sum (as a double) of all the numbers.
•Print out the sum (as an int) of all the numbers.

My rational number class :

public class RationalNumber{
private int numerator;
private int denominator;
public RationalNumber()
{
numerator =1;
denominator = 4;
