Use the Calendar-API        get Calendar instance Calendar cal   Calendar getInstance    cal setTime new Date         substract 7 days    If we give 7 there it will give 8 days back cal set Calendar DAY OF MONTH  cal get Calendar DAY OF MONTH -6       convert to date Date myDate   cal getTime      Hope this helps  Have Fun

Java now has a pretty good built-in date library  java time bundled with Java 8   import java time LocalDateTime  import java time format DateTimeFormatter   public class Foo       public static void main String   args             DateTimeFormatter format               DateTimeFormatter ofPattern  yyyy-MM-dd T HH mm ss Z              LocalDateTime now   LocalDateTime now            LocalDateTime then   now minusDays 7            System out println String format               Now    s nThen   s               now format format               then format format                                     Example output                  Now   2014-05-09T14 51 48Z                 Then  2014-05-02T14 51 48Z

Or use JodaTime   DateTime lastWeek   new DateTime   minusDays 7

You can use Calendar class    Calendar cal   Calendar getInstance    cal add Calendar DATE  -7   System out println  Date      cal getTime       But as  Sean Patrick Floyd mentioned   Joda-time is the best Java library for Date

You can use this to continue using the type Date and a more legible code  if you preffer   import org apache commons lang time DateUtils      Date yourDate   DateUtils addDays new Date     days here

For all date related functionality  you should consider using Joda Library  Java s date api s are very poorly designed  Joda provides very nice API
