How to get the date 7 days earlier date from current date in Java [duplicate]

Question

I am using

DateFormat dateFormat =  new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss'Z'"); Date date = new Date(); String fromdate = dateFormat.format(date); 

to get the current date, how can I get the date 7 days back. For example, if today is 7th June 2013, how can I get 31th May 2013 in the same format as defined in date formatter?

Update

Got the solution:

DateFormat dateFormat = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss'Z'");          Date date = new Date();         String todate = dateFormat.format(date);          Calendar cal = Calendar.getInstance();         cal.add(Calendar.DATE, -7);         Date todate1 = cal.getTime();             String fromdate = dateFormat.format(todate1); 

Answer 1

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.
