title: Java :Questions on clone method
body: <p>I got these asked in an interview.</p>
  <blockquote>
  <ol>
  <li><p>Do we need to take care of clone method in a concurrent environment ? Can we synchronize the clone method ?</p>
  </li>
  <li><p>Does it make any sense to use clone method in singleton classes ?</p>
  </li>
  </ol>
  </blockquote>
  <p>I did not have convincing answers for this during the interview.</p>
