title: Understanding java's native threads and the jvm
body: <p>I understand that the jvm is itself an application that turns the bytecode of the java executable into native machine code, but when using native threads I have some questions that I just cannot seem to answer.</p>
  
  <ul>
  <li>Does every thread create their own
  instance of the jvm to handle their
  particular execution?</li>
  <li>If not then does the jvm have to have some way to schedule which thread it will handle next, if so wouldn't this render the multi-threaded nature of java useless since only one thread can be ran at a time?</li>
  </ul>
