Calendar issue in Adding month +1 to to calendar month in Android

Question

I am using the following code

Calendar cal = Calendar.getInstance(); System.out.println("Before "+cal.getTime()); cal.set(Calendar.MONTH, 01); System.out.println("After "+cal.getTime()); 

the output is

Before Thu Jan 31 10:07:34 IST 2013 After Sun Mar 03 10:07:34 IST 2013 

for adding +1 to jan is giving mar month. may be it returning correct output if we add 30 days to present date. but i want to show feb month. can any body help me please..

Answer 1

you can see the +1 to set field is adding 30 days date different to your dates(observed from your output.)

if you want months then use the code

Calendar cal = Calendar.getInstance(); System.out.println("Before "+cal.getTime());  //Before Thu Jan 31 10:16:23 IST 2013  cal.add(Calendar.MONTH, 1); System.out.println("After "+cal.getTime()); //After Thu Feb 28 10:16:23 IST 2013 

Answer 2

You have to use add() like,

cal.add(Calendar.MONTH, 1); 

OUTPUT ->

Before Thu Jan 31 10:15:04 IST 2013 After Thu Feb 28 10:15:04 IST 2013
