In java, how to get the first and last date of the previous month?

If I am not wrong the following code is to get the last date of the previous month.

Calendar aCalendar = Calendar.getInstance();
aCalendar.set(Calendar.DAY_OF_MONTH, -1);    
aCalendar.add(Calendar.DAY_OF_MONTH, -1) ;
System.out.println(new Timestamp(aCalendar.getTime().getTime()));

Correct me if I am wrong.

Thank you.

You say "*Correct me if I am wrong*". What do you see when you run this code? — Lion, Aug 17 '12 at 10:08

Use getActualMaximum()

Calendar aCalendar = Calendar.getInstance();
// add -1 month to current month
aCalendar.add(Calendar.MONTH, -1);
// set DATE to 1, so first date of previous month
aCalendar.set(Calendar.DATE, 1);

Date firstDateOfPreviousMonth = aCalendar.getTime();

// set actual maximum date of previous month
aCalendar.set(Calendar.DATE,     aCalendar.getActualMaximum(Calendar.DAY_OF_MONTH));
//read it
Date lastDateOfPreviousMonth = aCalendar.getTime();

aleaCalendar.setCalendar.DATE, 1); this line has to be modified to aCalendar.set(Calendar.DATE, 1); – sandeepkunkunuru Apr 02 '14 at 02:55
