I got a book titled "Head First Java" which seems to be a really cool way to learn Java, under the "what you need for this book" section they let you know that you need J2SDK along w/ API documentation. I have these things, however something confuses me. The book says the following:
"You need to add an entry to your PATH enviroment variable that points to the /bin directory inside the main Java directory."
I need this in order to run the javac compiler, and I have no idea how to add this entry. Some insight would be great, thanks.
