Here they are! somkiat... There are plenty of examples as well...

Hope it helps you and all other ranchers out here who are interested in Tiger...

Seems to me that most new features are basically simplify the coding structures.

In addition to Enumeration datatype, are there any non-syntax wise new features?

See. That's one of the reasons why Sun has changed its name to Java 5.0, instead of J2SE 1.5...

is the new Java tiger worth using if we are currently developing software using J2SE 1.4 comfortably and efficiently?

I was wondering this too. The lack of major changes in Java (at least, J2SE) over recent years has been quite welcome for us. I don't find that Java is missing much at the moment, maybe i'm just living in the past

Tiger is a break through of J2SE. You may find lots of areas that have been greatly improved a lot.

For IT industry, it is better for us to be always up-to-date, so that when new things really come to real development/applications, we are already know them.

Well, if we could, our team would jump to using Tiger yesterday - mainly because of generics. Unfortunately, we are probably stuck with 1.4 for years (some of our projects still try to escape 1.3...)

I guess one of the reasons for the new language features such as enumerations, varargs and the new for loop is that Java has C# as a competitor language.

The generics are useful. Did they also get the threading improvements in?

A lot of the stuff just seems like language bloat - not surprising in a language like C#, but not necessarily suitable for Java.

The new for loops, for example, are quite cryptic ... they needed a keyword rather than a colon. (If the colon means "in", why not just use "in"?) I think they could have put in a context sensitive keyword without breaking existing code....

I wouldn't use 1.5 for anything that will be released within the next year or two, as it will take a while for virtual machines on various platforms to catch up.

Sun introduced as few new keywords as possible for upwards compatibility, e.g. old code should be able to compile with the new JDK. Such as mine, which has Reader <i>in</i> = new BufferedReader(...) sprinkled all over.

Here is the list of the major new features that I cover in my book:

Generics
Metadata (Annotations)
Autoboxing/unboxing
Enumerations
Enhanced, for-each style for loop
Variable-length arguments (varargs)
Static import
Formatted I/O
Various upgrades to the API

All of these features represent major enhacments to Java. However, generics is the most far-reaching in its impact on day-to-day programming, with autoboxing/unboxing coming in second. Enumerations are nice to have, and the "for-each" for loop is very convenient. The ability to easily format ouptut via the new Formatter class and printf() method is a real plus, especially for new Java programmers.

Perhaps the new feature with the most promise, however, is metadata (also called annotations). This feature gives you the ability to embed supplemental information into your program that can be used by tools. Although its a relatively small beginning, I can already guess where its going.

[Warren]: The new for loops, for example, are quite cryptic ... they needed a keyword rather than a colon. (If the colon means "in", why not just use "in"?) I think they could have put in a context sensitive keyword without breaking existing code....

Like Nicky, I use "Reader in..." and "InputStream in" fairly often. And let's not forget System.in.

I suppose Sun could make the new keyword context-sensitive, but to me that introducing unneceesry complexity to the language rules. All other keywords are simply illegal as identifiers. That's easy to understand. It's a bit odd to say that in is a keyword, but it's OK as an identifier unless it's the third word in a for loop. Easier to just let people use : - it's easy to adapt to; just a little odd at first. No big deal, IMO. If we were designing a new language from scratch it would be different, but we're not...

There's the java.util.concurrent package, that's the main new thing. Pretty useful if you're doing anything fancy with threads, IMO. There are also some other new features.

A majority of the many shops I visited over the past few years have not yet escaped 1.3. Often it's due to a dependency on a major third party framework. So I can understand the heavy emphasis of Sun on compatibility. Yet it still doesn't seem to sell the move to new versions as much as one might think or hope. My current client is just now moving to 1.4.

Does java.sql.Connection interface in 1.3 work in 1.4?

No.

1.3 code breaks.

I think , it's can work but may be some method is deprecated.

You can see more detail about compatability if java at ::
