I just download the sun JDK 1.02 version, and installed on my Win NT. I tried the first helloworld program. But when I run it, the program generates the message:"Can't find class HelloWorld".

Can somebody tell me what else I need to do to set up the environment right? Thanks.

Probably you need only to include the current directory "." in the CLASSPATH
SET CLASSPATH=%CLASSPATH%;.
when java searches for class files it looks through the CLASSPATH enviroment variable
(this is analogue to PATH for .exe files). the "." points to the current directory so
java will check the current directory too - and find the Hello.class (suppose that you
start Hello from the same directory where it is positioned)

So does this work ?
