I am thinking about learning to programme in Java. I have heard lots

"think" potential developers want to know, rather than what they "do"

already is a good thing in my opinion. Being a Linux user, catering
for Windows users is not always easy. The ability to be able to write
one program, and have it work on any machine that can run a JVM, is a
serious break through for me.

I've done some C++ programming in the past, but I couldn't get into
it. This was back in my Windows days, and I started getting fed up
with how Windows worked, or rather didn't work, so I gave up.

I'd like to know just how useful Java will be to me. Can I make games
with it? By that, I mean just like you'd make using Flash, but
hopefully more secure. Can I use Ajax over multiple domains freely, or
are there restrictions? I am heavily into web development at the
moment, and I have seen lots of Java applets about, but they are quite
self contained and standalone. Can Java interact with a browser? I
like the thought of being able to integrate Java into my Web site.
There are lots of Ajax Web sites popping up all over the place these
days, and I'd like to use Java in the mix if it's possible to do so.
Is this possible, or am I expecting too much?

What's the learning curve likely to be for someone who did some basic C
++ a few years back, and has spent the last 2 years dealing with
JavaScript and PHP (which of course are both quite low level

I would appreciate any input you may have to offer on the subject. I
am quite excited of the prospect of using Java for just about
everything, but I just need to be sure that the effort I put into
learning it will be well worth it, and that I am not rushing head
first into something that might not benefit me.

A Java applet can call JavaScript and JavaScript can call Java, so
there are interaction possibilities.

The Java applet security model is probbaly even more restrictive
than the JavaScript one.

The biggest problem with Java applets is users that either does
not have Java or have a very old version of Java.

If you know C++, JavaScript and PHP then I think you can
learn Java well enough to do some actual work within a few
