I am asking about the open source projects (where to fine) that I want to contribute my code to..

Java/Spring/Hibernate/JMS/JPA

these are the things that i am aware of and want to contribute.

Hi,

May I know where can I contribute Java code? any idea about the site, project or links?

Thanks in advance.

Sorry Greg, I am a learner not a Hacker!!!

Like Manoj, I'm not sure what you mean, but there's source code for almost the entire SDK. However, I suspect it's likely to hinder rather than help.

The idea is to learn how to use classes, not know exactly what's inside them. You don't need to understand how an engine works in order to drive a car.

How to get good knowledge of Java for all programming purposes. In other words, I am asking about good programming, desiging guides or links to practice and keep my head help high in the programming world.

may i know How to go to deepest part of the java coding? any links for practice? any other thing?

may i know if this is a wrong place to ask this kind of questions?

class PrePostDemo { public static void main(String[] args){ int i = 3; i++; System.out.println(i); // "4" ++i; System.out.println(i); // "5" System.out.println(++i); // "6" System.out.println(i++); // "6" System.out.println(i); // "7" } }


May i know why Line number 5 and 7 are giving incremented result but not line number 8 and 9.

why the result of increment (@ 8 and 9 lines) is not being directly reflecting on the output.

You can find a recommended hashCode method in Joshua Bloch's Effective Java™ or Bruce Eckel's Thinking in Java™ (TiJ); Eckel acknowledges Bloch there. You can find the 3rd edition of TiJ or a sample chapter of Bloch (old edition: try here) free of charge if you search the net. There are subtle differences in Bloch's recommendations in the 2nd edition.

My understanding is that from the effective java link mentioned above that, hashing checks if equals() and hashcode() contract is met or not. if met hashing is done otherwise hashing fails?

May i know how hashing works in java?

may i know where can i find AJAX FAQs, it is being difficult to find a proper website for AJAXFAQs

thanks in advance.

That is what it means for a class to implement an interface.

so LinkedHashMap is implementing Map interface for object reference purpose?

I don't think so. For one thing I don't understand what "functionality usage" means.

i was talking about using the method in different way. {forget about it} but any other use other than the one you mentioned above?

One use of that is this:
Map map = new LinkedHashMap();

very good answer but can you please give any thing in terms of functionality usage?
