What do you mean by a "realtime example"?

FWIW, the best writing on design patterns I've ever encountered is still Head First Design Patterns. It costs more than visiting a web site, but the cost is well worth it.

A lot of people in India seem to say “realtime” when they mean “real‑life”.

You shouldn't thing about "design patterns in java". a design pattern is language neutral. Yes, a specific pattern can be IMPLEMENTED in java (or whatever language you choose), but IMHO, you should focus on learning the concepts behind the pattern, rather than study a specific implementation.

By realtime/real-life I meant non-technical examples..

Hello Shweta,

"Real world/life" examples can be taken out of things that you do every day. Like an ATM transaction is something similar to a Singleton design . An EJB architecture - how things work in an EJB can be understood if you look around what happens when you go on a vacation to an unknown place and you have to ask your receptionist for a good restaurant(Home Interface- he gives you the address of the restaurant), you reach there by travelling all the way (remote JNDI Look up ), and you order stuff by looking at the menu (no implementation details just the list of items) and finally out of no where (hidden place - since you are not admitted in ( just like the Bean which you are not allowed to access directly)) you get the tasty food that you have ordered for .

Its up to you to choose the way you would like to learn. But I can safely say that JAVA or any design pattern as a concept is at best were/ are / will be taken out from things that happen around us.
(Please note : the real world examples that I have given are somethings that I imagined for better understanding of the concepts).

Hope this helps

Thanks and regards,
Raghav.V

"Real-life" is the term you want. "Real-time" is a context in which events unfold; the term is used in sports, music & video editing, computer applications such as vital-signs monitors (and I'd guess many other things, maybe GPS). It is distinguished from other contexts in which we can "stop the clock" to focus on a particular event.
