My questions to Benjamin J. Evans and Martijn Verburg are ...

JAVA 6 is a stable version that is widely in use and migrating from JAVA 6 to JAVA 7 would be meaningless unless there is any strong reasons for that !!

what are the features in JAVA 7 that could really be helpful for the developers ?

what are the improvements in JAVA technology that are introduced via JAVA 7 ?




Do you know why Java programmers wear specs ? Its because they don't 'C#'

Hi Richards,

There are many changes that have been introduced as part of Java 7. Some of which are in following areas:
1. Swings
2. IO
3. Concurrency
4. Security
5. Java XML, basically changes in JAXB, JAX WS, etc..
6. Changes related to how certain things were handled while Programming like multi catch, try with resources, type inference for generics, allowing use of String in switch statement, etc.

For details you may want to check Java 7 release notes: http://www.oracle.com/technetwork/java/javase/jdk7-relnotes-418459.html
If these things interest you and are helpful for your work, then go for it. Anyways Java is changing and if there are no constraints at your end, it is better to change!!

Palak has covered much of this, but in short, it's faster out of the box, more secure out of the box and has several new features that ensure developers write safer code with less boiler-plate. So lots of reasons to upgrade :-)

I mean.. is the migration really essential or is it like if you want you can ??

JAVA 5 was a major release because a lot of new stuff like auto-boxing and lot more cool stuff were introduced !! it marked the beginning of a new JAVA era !!

is JAVA 7 that sort of a release ??

It depends what you intend to use it for :-). For me it's an important enough release to migrate to and since Oracle is no longer supporting Java 6 after November 2012, I'd be looking to move regardless :-)

You can't migrate unless the app server you are using support Java 7, right?

If you're dealing with web apps, that's correct.

Oracle is not going to support java 6 after November 2012 ?? does that mean taking up the OCJP for java 6 is not possible after November ??

Don’t know. Have you tried the Oracle/Java website?

  Java, not JAVA. It's not an acronym.
