You can use the Calendar class.

Calendar cal = Calendar.getInstance ();
int dayofWeek = cal.get (Calendar.DAY_OF_WEEK);

cal.add (Calendar.DATE, -1 * (dayofWeek - Calendar.MONDAY));
Date fdow = cal.getTime ();

As the cal object is now modified, just add six to get the last day of the week.

cal.add (Calendar.DATE, 6);
Date ldow = cal.getTime ();

Using the third-party Joda-Time makes it a bit easier.

See the question Get first day of a particular week in Joda-Time? java.

@Krishna You can do most of your work in Joda-Time objects and then at the end convert to a [java.util.Date](http://docs.oracle.com/javase/7/docs/api/java/util/Date.html) object. Be aware of time zone, otherwise very simple to do. See the question, [How to convert Joda-Time to Date of java.util.Date and vice versa?](http://stackoverflow.com/questions/15333320/how-to-convert-joda-time-to-date-of-java-util-date-and-vice-versa) – Basil Bourque Nov 15 '13 at 18:23
ya you are right. but if u dont mind can i ask you for one favor?? can u just paste a sample code in answer so i can have better idea. – Kishan Bheemajiyani Nov 16 '13 at 04:41
@Krishna I already gave you links to two other questions whose answers include such source code examples. Also, you have not yet cleaned up your question for clarity as requested by the moderators. So how can I write example code when the question is not yet clear? – Basil Bourque Nov 16 '13 at 04:58
just do one thing take 2 Joda Date and take one particuler date form that and find out that particular week date and show firstday of week date and lastday date of that week. and convert it to java.util Date. – Kishan Bheemajiyani Nov 16 '13 at 08:35
