A question about JAVA path???

Question

I have a problem with the imput "cs1". Notice that every time I compile the fie, it shows "The package cs1 does not exist". Afterward, I recognized that I need to find configure path (Keyboard class, package cs1) since is's not part of Java standard class library. Here's my java file: anyone can help me, THANKS A LOT~!

import cs1.Keyboard;


public class Echo
{
public static void main (String[] args)
{
String message;

System.out.println ("Please type in: ");

message = Keyboard.readString();

System.out.println ("You just entered: \"" + message + "\"");

}
}

with JCreator

Answer 1

message = cs1.keyboard.readString();

You have to use the full path when you import

Answer 2

You need to add whatever jar file has your cs1 package classes in it to the CLASSPATH. From a command line, it's easy to define the CLASSPATH variable using "set". I'm not sure how to do this in JCreator, but looking up CLASSPATH in the help should give you the info you need.
