title: Getting javac to work in the PATH environment variable
body: <p>So I've downloaded the latest JDK and installed it.
  I'm starting to go through a textbook with some tutorials but in no part of the textbook do they tell you how to 'setup' the javac compiler. If I type 'javac' into the command line it simply says it is not a recognised command. I have added the path of the bin folder to the path environment variable but it still says not a recognised command. Please help!!</p>
