I'm having one requirement such that 0001 should be incremented to 0002 but when we use regular + operator its giving 2 instead of 0002 how to add including zeros also

If you are referring to integer types, then try to print it out before you increment it. You will notice that it is printed as 1 and not 0001. Integer types do not have a format, you'll need to add it yourself during printing.

yes, as henry suggested, you apply format. in Java 5.0 you can do like below,
String formatValue = String.format("%04d", intValue);
<edit>changed the format %03d to %04d</edit>

There is a difference in the VALUE, and how it get's DISPLAYED. the number '2' has the same value regardless of me writing it as "2", "two", "II", or any other way.
So you really have two requirements.
1) You need to increment the value of '1' to '2'
2) You need to display these values with some leading zeros.
The best way to approach this is to figure out how to do each individually, and only THEN figure out how to combine those steps into a single program.
There are only two hard things in computer science: cache invalidation, naming things, and off-by-one errors

Presumably 1 is decimal and 0001 is octal?
I agree. Here's the link:
