title: Getting Computer Memory information in Java
body: <p>Is there any application for <strong>memory testing</strong>, preferably written in <strong>java</strong> (or another programming language) that shows information about <strong>computer memory</strong> or something for testing it (something like <strong>total memory</strong>, <strong>free memory</strong> , <strong>processes and memory consumption</strong> etc.). I want something like the <strong>resource monitor</strong> from <code>Windows</code>: <img src="https://i.stack.imgur.com/dDSJr.jpg" alt="Resource Monitor screenshot">  ... or something similar. </p>
  
  <p>I need the source code.</p>
