Passing rational number as parameter??

Question

Hi i need to write a rational number class that adds/subtracts etc two rational numbers when i run the program i can enter one rational number but when i go to add subtract or whatever an try to enter another rational number as a parameter i get found int but expected Rational. I am trying to enter like 1/100 but it says its an int? How do i enter a rational as a parameter.
A code template was provided and i completed it as seen below. What is the problem?
public class Rational
    private int num;
    private int denom;
    public Rational()
    public Rational(int n, int d)
        num = n;
        denom = d;
    public Rational add(Rational rhs)
        return new Rational(num*rhs.denom+rhs.num*denom, denom*rhs.denom);
    public Rational subtract(Rational rhs)
        return new Rational(num*rhs.denom-rhs.num*denom, denom*rhs.denom);
    public Rational multiply(Rational rhs)
        return new Rational((num*rhs.num), denom*rhs.denom);
    public Rational divide(Rational rhs)
        return new Rational((num*rhs.denom), denom*rhs.num);
    public String toString()
        return (num +  "/" + denom);    
    public static void main(String[] args)
        Rational r1 = new Rational(1, 2); 
        Rational r2 = new Rational(3, 4);
        Rational result = r1.add(r2);
        System.out.println(result);
}Any help appreciated!

How should Java know that you want it to use your Rational class in this case? Hint: it doesn't.
If you want to pass a Rational as the argument, then you need to construct one. Try using "new Rational(1, 100)" (without the quotes, obviously) as the parameter.
