This week's book giveaway is in the OCAJP 8 forum. We're giving away four copies of OCA Java SE 8 Programmer I Study Guide and have Edward Finegan & Robert Liguori on-line! See this thread for details.
I've done a tiny bit of java from netbeans, but need to learn it to a much higher level. I've started the "Head First Java" book, which recommends that you do the exercises with a simple text editor and use the javac compiler. So I've been following the instructions here (http://download.oracle.com/javase/tutorial/getStarted/cupojava/win32.html) for doing the "hello world" app with text files and from the command prompt. I can get into the java directory and see the file I've saved there, but when I type "javac HelloWorldApp.java" I get the following error message: ' javac' is not recognized as an internal or external command, operable program or batch file.
