Hi,
I am quite new to java.
I am very curious to know about the application area (domain) where core java programming (Java Standard Edition) is used.
What I mean is the industries where core java programming is used in the commerial world.
Could some one help me out with this query?
Regards
Paresh

Standalone desktop applications?

enterprise applications that don't actually use any j2ee packages? (like the one I'm working on now)

you want a list of enterprise applications that don't use j2ee? how are we supposed to know? I know of exactly one, because I'm working on it now
you can make use of j2se knowledge because the majority of the work in a j2ee project will still be core java. j2ee isn't a separate langauge, it's a set of standards and APIs that extend j2se

It probably won't.
I've been ivolved in projects where we used j2se to:
* build a desktop application for gene analysis
* build a distributed system for distribution of digital content (ring tones etc)
The similarites are close to zero.

tell you what about it? I'm a java developer, building retail systems. it's not web-based, we have a swing fat client, so no j2ee there. we use spring as a container and hibernate for persistence. hibernate manages our transactions for us, so still no j2ee there. what else do you need to know?
actually, I tell a lie. we've got a small component that serves address and postcode queries from a web app. that's a servlet, so technically j2ee. but not really

Not in our neighbourhood! They scare pedestrians with their cars, but not as much as school buses.
It might also help having a pilot license to work in Pizza Hut.

where on earth (or elsewhere?) was he delivering to?
paresh,
Most java development is in J2EE these days.
I know of 5 J2EE projects (from accounting through to GIS)
verses 0 completely-non-J2EE projects
verses 1 .NET fat client integrating msOffice stuff - run away!
I imagine that military are the only ones with the budget to do "real" java projects.
... anyway I wouldn't get too hung up on "which industry", just get yourself a good pimp and go wherever he tells you to... that's how most programmers work.

Core Java is used everywhere unless you need to use the Micro edition. If you need the Enterprise extentions you add them to Core Java. If you need other extensions (libraries) you add them too.

Any jobs that don't require what J2EE adds.
Look at J2EE. See what it provides. Now look at the requirements for your project. Do they include features that are part of J2EE? If so, then you need J2EE (or need to roll your own). If not, then you don't.

Lots of reasons, like when you're developing a fat client using EJBs.
And with the JEE spec incorporating ever more that's traditionally part of JSE you're likely using it without even knowing it.
JavaMail, JDBC, JNDI, etc. etc. are all now part of JEE for example.

True, but I think that those systems are in minority.... and I hope that they will die :)

But e.g. JDBC is also part of JSE so I don't consider it to be a JEE application if the rest of the application only uses JSE.

I thought you were talking about these: http://images.google.co.uk/images?q=crunchies+cadbury%27s
"Pay up, or I'll shove it up your nose!"
I work in the games industry, and have never touched J2EE. Currently I don't get much mileage out of my knowledge of the J2SE libraries either, because I'm mainly working with an in-house game engine.
