Java Time

[Valmont]

Can you provide me links to complete Java Development Environments and everything I need.
The IDE must be as professional as it gets. Commercial versions are welcome too. I am not familiar with the Java worlds. I appologise for this extra reminder.

Also links to tutorials on Java for serious/experianced programmmers.

The final goal is science apps and general online web applets.

First link: java.sun.com. This is the site maintained by Sun and devoted to Java. This includes core Java, extensions, tutorials, guides, documentation, and message boards.

Now, you'll want (probably) the J2SE 5.0 SDK download available here. The default package comes with Netbeans, which I've grown to enjoy a great deal as an IDE, and it was designed specifically for Java programming. The current version is 4.0 Beta 2, so it might still be a little rough around the edges, but I've been using Beta 1 for a while now, and it holds up fine.

The alternative is Eclipse. I haven't used Eclipse, so I can't comment on it, but it seems to be about as popular as Netbeans. Seems to be a vi vs emacs type situation.

You'll want to bookmark the API, which details all the Objects available with the core download.

Sun tutorials can be found here. I usually just hit google if I need something else.

The Java Tutorial would be a good place to get up to speed quickly. Of specific note is the Language Basics that I still occasionally refer to because it covers the language syntax in a quickly-referenceable manner.

Oh, and for compiling, you might want to look at Ant as a comile manager. Netbeans includes Ant by default, but I had been using Ant as a standalone for so long I just kept doing it that way.

Say... this is fun. I can really relax while coding. Right now I am exploring the power of the gui editor. Nothing big yet. Then I'll try to oversee the whole part of the Java coding world, like adding sources, creating the final executables (however they are called), memory management, and why it creates all those extra folders (and how to use them).

But first a bit gui fun. I've got a book right here (O'Reilly, Nebeans 3.6).

The fun part of Java is that you don't need to do much with memory management; often you don't need to do anything at all.
