I am using below code,

private static Date date = new Date (2014-1900,11,25); 
System.out.println(date);

It is displaying 2014-12-25. I am unable to understand why it is giving me date as 12?

and if i give 

private static Date date = new Date (2014-1900,12,25);

it is returning 2015-01-25.

Can anyone help in comprehend this?

Calendar

It accept December month as 11 because month starts from 0 - 11

First you should not use this Constructor, because it is deprecated.

Second: See the documentation of this consturctor:

Parameters:year - the year minus 1900.month - the month between 0-11.date - the day of the month between 1-31.See Also:Calendar

month is a null based value, so 0 --> Jan ... 11 --> Dec

from java docs,

Parameters:
year the year minus 1900.
month the month between 0-11.
date the day of the month between 1-31.

Month's range from 0-11, ie Jan - Dec

Avoid using the depriciated Date() constructor for setting dates, It is recommended to use Calendar class

Calendar calendar = Calendar.getInstance();
calendar.set(Calendar.YEAR, 2014);
calendar.set(Calendar.MONTH, Calendar.NOVEMBER);
calendar.set(Calendar.DAY_OF_MONTH, 25);
Date date = calendar.getTime();

You can also use the simpleDateFormat for setting/formatting date values:-

SimpleDateFormat sdf = new SimpleDateFormat("dd-MM-yyyy");
Date date = sdf.parse("25-11-2014");

  • using a simpledateformat to initiate a date is just a waste of CPU cycle and possible threading issue – Peter Jan 09 '15 at 07:05
  • But it is better to waste a cpu cycle rather than wasting time setting dates using `new Date (2014-1900,11,25);` and wondering what went wrong. – Mustafa sabir Jan 09 '15 at 07:08
