.NET vs. Java

[Arich Chanachai]

What are the pros and cons of Java?
How does Java measure up to .NET in terms of speed?
How about in terms of depth of classes?

I am looking for garbage collection while at the same looking for speed.
Java and .NET seem to be the only two application platforms offering
both, any suggestions?

Thanks all!!

A couple of days ago, I read this:

"Conflicting mindsets of C# vs. Java"

The difference is not features, but mindset.

Great article, thanks. Still doesn't answer my Qs as I'm sure there ARE
differences in speed and some cases features as well. I wonder if he is
right about Java eating DotNET. We shall see. An open source version
of DotNET called Mono is in existence and under constant development. I
wonder if they will integrate the Java DotNET tools.

How big of a difference is going to make or break you? I asked this
question of the head computer science guru at a place I used to work a
bit ago. He said that Java is an interpreted language and therefore a
little slower and less apt to be used in software where clock speeds
and critical timing are important.

I am not saying Java is not useful or good... I am learning it now and
love it. More than I liked C++ 6.0 when I learned it.

But I am a strong beleiver in the statement made earlier that the
difference is in mindset and not in features. I also think there is a
proper tool for every job... so dont look for just one solution to
every problem in existance.

The "fact" that Java is slow is a myth.

See for examples these benchmarks:

Java is slow with trigonometric functions (like sinus).

Looking at the other tests, Java is comparable to C++!

How is that possible? Java compiles the byte code to fast machine code.
And because Java compiles the code while the program is running, it can
make better optimizations than a oridinary "compile-before-running"
compiler.

Also because Java doesn't know pointers also makes it possible to make
some serious optimizations a C++ compiler can't make.
