Question

I have a Date object. Now I want to add days to that Date object.
So how that can be done? Actually using Calendar object that can be done I know.
But in my case, I haven’t used a calendar objects. Instead only used date object.

For Example, suppose I have a date object

Date dtStartDate=o.getStartDate();

int x=28;

Now what I want to do is to add 28 to this date object, means if the dtStartDate is 1 July 2011
then after adding 28, dtStartDate will be 29 July 2011.
Please suggest it to me.

Thanks in advance

Answer 1

You can add Day using below

Calendar c1 = Calendar.getInstance();
c1.add(Calendar.DAY_OF_MONTH, 1);

Here 1 is number of Day you can add.

OR

Date dtStartDate=o.getStartDate();
SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd HH:mm");
Calendar c = Calendar.getInstance();
c.setTime(dtStartDate);
c.add(Calendar.DATE, 3);  // number of days to add
String dt = sdf.format(c.getTime());  // dt is now the new date
Toast.makeText(this, "" + dt, 5000).show();

May be your problem solved.
