title: Setting up enviromental variables in Windows 10 to use java and javac
body: <p>I got a new laptop with Windows 10 and I want to set it up so I can use <code>java</code> and <code>javac</code> from the command line.</p>
  
  <p>I have searched online but all the guides are for previous versions, and I don't want to mess around with something I don't understand.</p>
