title: How to determine the date passing the Week Number and Day Number (Week) in java
body: <p>I need to get the date by passing these parameters</p>
  
  <ol>
  <li>year</li>
  <li>week number (in a month) i.e. 1,2,3,4,5</li>
  <li>day number (in a week) 0 (Sunday) to 6 (Saturday)</li>
  <li>Month</li>
  </ol>
  
  <p>I looked for a constructor in <code>Calendar</code> class but does not contain these parameters.</p>
