How many of us are using Java 1.5?

[Owen Densmore]

I just downloaded the most recent Mac OS X Java 1.5 developer release  
(1.5.06) and was quite surprised that it flipped the Mac desktop java  
default from 1.4 to 1.5.  Presumably this means Mac is considering  
making 1.5 be the default desktop and browser java soon.

I've tried the new 1.5 with both NetLogo and Eclipse and so far, so  
good.  It also seems to work with the Safari browser .. after  
changing the plug-in settings (/Applications/Utilities/Java/).  It  
appears also to work fine with Processing3D although they recommend  
against its use.

So this is for Java developers our there:
   - Have you begun to use 1.5?
   - Any interesting stories/opinions about using it?

As you probably can tell, I'm lusting after the for-each and generics  
and auto-boxing and enums and annotations and var-args and ...

I haven't, but I've paged through the O'Reilly Developer's Notebook on
it and it really does look like an absolutely massive improvement.

Java 1.5 in a (Marko's) Nutshell ->

 1. Generics:

Vector<String> names = new Vector<String>();
names.add("Marko");
for(String name : names)
{
        System.out.println(name);
}

Thats all I use it for that is different than 1.4.

That's about the level of my use of generics too. And it certainly makes a
big difference to code readability (none of those damn casts every time I
pull something out of a collection). But there's a bunch of stuff around
generics and type parameter wildcards (bounded and unbounded) and writing my
own generic types that I'm completely failing to understand. Which is a
pity, because I suspect that there's some handy tricks lurking in there.

I think the high order bit here is to always ask yourself, "what if I
wrote into the collection?"  For example, suppose you write a function
which takes a collection of Numbers, and you pass it a collection of
Doubles.  It's ok to get() elements from the collection and cast them to
Numbers, but you shouldn't be able to insert an Integer into the collection.

I think that's the key insight; if you keep asking yourself "but what
about writing into the collection?" I think it will make a lot more sense.

The best book I've found for 1.5 enlightenment is:
   Java 5.0 Tiger: A Developer's Notebook (Paperback)
   by David Flanagan, Brett McLaughlin
   http://tinyurl.com/ojq7g

I think I've gotten my head around most of the nifty features with  
Generics, and you're right: there's a lot hiding under the covers.

I like the new OReilly Notebook format: very direct and to the point.

Robert,

Owen and a few of us are at Tom Johnson's very interesting ver 1.0
conference today (http://www.ver1point0.cjb.net/). How about the week after
next? Next week's Wedtech, will have Lee Hoffer presenting Ethnographic and
ABM research on the Heroin market in Denver. Abstract to follow.

-Steve
