title: Get all of the Classes in the Classpath
body: <p>How can I get list of all available classes in <a href="http://docs.oracle.com/javase/tutorial/essential/environment/paths.html" rel="noreferrer" title="ClassPath"><code>CLASSPATH</code></a> at runtime?<br>
  In Eclipse IDE, you can do this by pressing <kbd>Ctrl</kbd>+<kbd>Shift</kbd>+<kbd>T</kbd>.<br>
  Is there any method in Java to get it done?</p>
