title: Why System.getProperty doesn't return value from System variables in windows
body: <p>I have this system variable</p>
  
  <p><img src="https://i.stack.imgur.com/WUQDW.png" alt="enter image description here"></p>
  
  <p>this code:</p>
  
  <pre><code>System.out.println(System.getProperty("area"));
  </code></pre>
  
  <p>returns null.</p>
  
  <p>Could I get acces to system variables from java code through System.getProperty method ?</p>
  
  <p>P.S
