- can also have some features removed ;-) especially deprecated ones. You can have a look at the API:

Actually its 2 different version's. My 1st jdk that I've used was 1.2 and I can definitly say that
there are lot of changes needed by this version.

There came 1.3 and now its 1.5 so main difference of version is upgrades :)

You can compare then compare them :

JDK 1.2 API : http://utenti.lycos.it/yanorel6/2/ch02.htm
JDK 1.4 API : http://java.sun.com/j2se/1.4.2/docs/api

Hope that helps . . .

If new things are added and bugs are fixed they are added in new releases sometimes
beta or the the final release.

Hope that helps . . .

deprecated fetaures, are not removed features :)
can't think of anything that has been removed off the top of my head between 1.2 and 1.4.

I meant - what is deprecated in one version would be removed in the future version.

>> can't think of anything that has been removed off

As a matter of fact, even I don't remember anything something being removed.

The difference between jdk 1.2 and 1.4 is the version with lots of additional classes

objects, System.getenv() was effectively removed in 1.4  (re-added in 1.5)

psk_karthik, many many things that were missing and that we started to write ourselves
are now in 1.4, and thus standard.
You can always use 3rd party classes, but it's better to find them in JAVA itself.

;JOOP!
