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!

In the command prompt window instead of:
javac HelloWorld.java
type full path to javac, it must be like:
"c:\Program Files\Java\jdk1.7.0_02\bin\javac.exe" HelloWorld.java
.
