Calendar.Month gives wrong output

Question

I have been using java.util for all date and calendar representations. But I am facing a strange problem here. Calendar.MONTH, Calendar.DAY_O

Answer 1

Calendar.MONTH doesn't return the current month. It is a constant whose value is 2.

From the source:

public final static int MONTH = 2;

It is for use as a parameter in Calendar's get method

public int get(int field) {...}

The design of Calendar is from the early days of Java, when many of today's conventions were different, non-existant, or developing. Oracle (and earlier, Sun), would never let an API like the java.util.Calendar API become part of the standard API today.

And, for completeness, use Joda Time instead of Java's Date and Calendar API's.
