I was just wondering if there's a Java IDE that lets you step thru
code
and examine the values of variables and such.

There are a number of them. I use NetBeans. It is free, but others will
differ in their recommendations. Eclipse is also popular.

If you get NetBeans and you are primarily looking for a good debugging
platform, you should probably stay away from the beta. It works pretty
well, but I've noticed a few problems when debugging with it. The 5.5
version works great.

I'm using NB 6 beta and have not noticed trouble with the debugger. What
scenarios give you difficulty, and what are the symptoms?

FWIW I'm using NB 6b on my Fedora Core 7 box.

If you hit the step button too quickly it starts a new instance of the
program with you stepping into main. That's the big one. I've found it
quite annoying when I'm trying to just get through a few lines of code.

I'm using it on Ubuntu, but it shouldn't matter.

I'm using the NetBeans daily builds on a Windows XP machine with JDK 1.6, and I
have never noticed this behaviour. Which Java version are you using?

Latest of 1.6. On Linux running Ubuntu.

Almost all of them. There's a console program called jdb that also allows
this; it comes as part of the JDK.

That is pretty much standard now. Check out Netbeans, Eclipse,
IntelliJ.

see http://mindprod.com/jgloss/ide.html

It is a lot slicker than the old days when you single stepped machine
language, and saw all the values in hex with no variable names.

Java now has an API for IDEs to use to do the debugging. The IDE needs
only provide the visual shell. All the weird tricky stuff is built
in. This means it is a lot less work now to add reliable debugging to
a browser. The pleasant net result for us programmers is debugging is
becoming standard.

This API is very powerful. It can be used, for example, to hotswap versions
of a class without taking down the JVM.

I personally prefer IntelliJ IDEA, but its a commercial product (you
have to pay for it). You *can* get a free trial though. Older versions
of it sucked, but since 5.0 (they're on 7.0 now) its been much better.

There are some free alternatives (others have replied with them). I
don't use them so I can't comment.

Although, I think Java comes with a free text based debugger. jdbg maybe.

IDEA also has good support for Refactoring, code search, ANT, and it has
tons of plug-ins.

Hope this helps,
Daniel.
