title: Trouble with Running Javadoc
body: <p>My java textbook says that in order to document a class using javadoc, all I have to do is enter "javadoc SourceFile.java" into the command prompt. But when I do this it says "'javadoc' is not recognized as an internal or external command, operable program or batch file."</p>
  
  <p>Can someone please tell me what's wrong?</p>
