title: Run external java class (projects)
body: <p>I want to run an external Java project (class) from inside a java project. I don't mean whatever program (eg. EXE files) but java classes (projects).</p>
  
  <p>Let consider you have the class file path in a string:</p>
  
  <pre><code>String = "C:\\test\\test.class";
  </code></pre>
