ThreadPool and JobQueue
<ol>
<li>Manager specifies the jobs into the job queue(Queue Size is not fixed).</li>
<li>Threads are maintained by fixed number of ThreadPool.</li>
<li>Whenever there is a job in job Queue, Frame assigns Threads from ThreadPool to the job.</li>
<li>If there is no Job in the Queue, Then the thread needs to wait until the job arrives. (Step 3 &amp; 4 repeats on)</li>
</ol>

<p>How may i implement these, if possible mention the code also.</p>
