I am a beginner in Java programming. I just downloaded JDK 1.7.0 to my Windows 7 laptop and wrote my first "Hello World!" program. I went to the command prompt and typed in javac HelloWorld.java and get the following response: "javac is not recognized as an internal or external command, operable program or batch file". I have tried editing the Path file but I'm still getting issues. Any help will be appreciated! Thanks!
