Java / Keyboard class, neophyte stumped

[the_edwards@ameritech.net (Chuck)]

I am tryin to use the Keyboard class included
in a book by John Lewis.  I get the following 
error messages:
C:\MyJava\EvenNumber.java:9: cannot resolve symbol
symbol  : class keyboard  
location: package cs1
import cs1.keyboard;
           ^
C:\MyJava\EvenNumber.java:26: cannot resolve symbol
symbol  : variable keyboard  
location: class EvenNumber
		num = keyboard.readInt();
                      ^
2 errors


Here is my code:

import cs1.keyboard;
import java.io.*;


public class EvenNumber
{

	public static void main (String[] args)

	{
		int num=0;
		int sum=0;
		int test=0;

						// keyboard input
		System.out.println ("Input any integer over the value of 2: ");
		System.out.println (" ");
		num = keyboard.readInt();

		while (test == 0)	//loop to repeat test for >2 condition
		{

			if (num < 2)	//Test to determine if the number is over 2
				{
					System.out.println ("The number you entered was less than 2");
					System.out.println ("Please enter another integer: ");
					//	num = Keyboard.readInt();
					test = 0;
			 	}
			else
					test = 1;

		}



				// loop to add all even integers
		for (int i=0; i<=num; i=i+2)
			{
				sum=sum+i;
			}
				// print out results
		System.out.println ("The sum of all even integers between");
		System.out.println ("2 and your integer, "+ num + ", is: " + sum);
		System.out.println (" ");
