New to Java

Please help,

I'm very new to Java and I can't get this code down. I have included coments within the code to explain what is should do.

It should print out like this:

Enter numerator; then denominator.
5
8
5/8

Enter numerator; then denominator.
4
10
4/10
Sum:
82/80
1.025
Product:
20/80
0.25

Enter numerator; then denominator.
6
0
infinity


The first one is the driver class, which I must be missing some information:

public class DudeProg7
{
   public static void main(String[] args)
   {
   Scanner stdIn = new Scanner(System.in);
   Fraction c, d, x; // Fraction objects

   System.out.println("Enter numerator; then denominator.");
   c = new Fraction(stdIn.nextInt(), stdIn.nextInt());
   c.print();

   System.out.println("Enter numerator; then denominator.");
   d = new Fraction(stdIn.nextInt(), stdIn.nextInt());
   d.print();

   x = new Fraction(); // create a fraction for number 0

   System.out.println("Sum:");
   x.add(c).add(d);
   x.print();
   x.printAsDouble();

   x = new Fraction(1, 1); // create a fraction for number 1

   System.out.println("Product:");
   x.multiply(c).multiply(d);
   x.print();
   x.printAsDouble();

   System.out.println("Enter numerator; then denominator.");

   x = new Fraction(stdIn.nextInt(), stdIn.nextInt());
   x.printAsDouble();
   }// end main

Here is the error I get on this:
D:\School\Intro to Programming\DudeProg7.java:39: reached end of file while parsing
}// end main
^
1 error

Tool completed with exit code 1

I know it's a closing bracket somewhere and I bet there are other issues too.

Here is the driver:

/**************************************************
* Fraction class that should do the following:
*
* add - This method receives a Fraction parameter 
* and adds the parameter fraction to the calling object fraction.
*
* multiply - This method receives a Fraction parameter

*
* print - This method prints the fraction using fraction notation (1/4, 21/14, etc.)
*
* printAsDouble - This method prints the fraction as a double (0.25, 1.5, etc.)

    public Fraction()
	{
		this(0, 1);
	}
    public Fraction(int numerator, int denominator)
	{
		this.numerator = numerator;
		this.denominator = denominator;
	}
    //*******************************************************
    //this method adds fractions.
	public Fraction add(Fraction d)
	{

	}
	//*********************************************************
	//This method multiplies fractions.
	public Fraction multiply(Fraction d)

		this.denominator = denominator * d.denominator;
		return d;
	}
	//********************************************************
	//This method prints the fractions in fraction notation.
	public void print()
	{
		System.out.println(numerator + "/" + denominator);
	}
	//********************************************************
	//This method prints the fractions as a double.
	public void printAsDouble()
	{
		System.out.println((double) numerator / (double) denominator);
	}
}

This compiles, but when I run the program I get this:
Exception in thread "main" java.lang.NoSuchMethodError: main
Press any key to continue . . .

Your help is greatly appreciated!
