I think you'd be very surprised about all the thing Java can do.

Ha ha. I requested not byte array, but STRING! Try to convert this array
to string and you will see that this is not so easy :)

Andrew,
byte[] yourDigest = ...;
String yourDigestAsString = new String( yourDigest );
Anyway, discussing about the power of a language based on this
question is a nonsense and really off track.

Re: [gentoo-user] Java error-SOLVED
Thank you Ragu, that solved my problem.
Sorry for almost starting a flame war based on language preferences. It was
not my intent. But thanks for the reading material! ;)
And to Norberto Bensa:
Thank you very much for telling me to read up on Pet Hate. Appreciate the
advice. However, i felt that writing that email was appropriate because java
in gentoo is handled differently than other linux distros( might i even go as
far as to say to improved??) via java-config. And if i was to bring this up
in another list, say a generic java list, they might not know enough about
gentoo to help me out if this was a gentoo related problem. It wasn't, but i
didn't know that when the problem occurred.
Thanks everyone for helping in your own little ways.

Bryce,
This error occurs, when the classpath is not set properly.
You have to set the classpath before running/compiling your
java files.
export CLASSPATH=$CLASSPATH:current-dir
Hope this helps you out.

This is indeed the wrong place to discuss basic java programming, but
anyway.
I suspect you issued:
java Main.java
rather than:
javac Main.java(compile)
java Main (run)

I'd like to get 5d41402abc4b2a76b9719d911017c592 from hello. I could mock something up, but it's besides the point actually. Any good programmer chooses the toolset that best suits the task ahead. I've been programming in a multitude of languages over the years, and the one thing I've learned is that there simply isn't any best language Currently I use C++ as a general purpose language, I use borland's delphi or kylix if i want a quick GUI, i use java if i want to build something that need to run as is on a few platforms. At the company where I work (ref. sig), I'm responsible for the networking core code, and as such use C++ for most my work due to strong ties to OS specifics. The people that work with the high-level logic parts use java, avoiding a memory management hell in an extremely complex design. The windows launcher for our product's currently a Delphi thing, because it took 30 mins to get a decent GUI for it. The core number crunching and graphics engine is C++, to squeeze as much performance out of it as possible. My point is, you can't simply claim that a language is bad. It might be bad for your purpose, but that doesn't mean it's a generally bad language. Sure, there might be failed languages that doesn't suit any particular task well, but most of the languages that're being used today are better than others for certain tasks. Now, back to MD5. If i needed MD5 functionality, I'd use OpenSSL's implementation. It's premade, it works. I could ofcourse write a MD5 implementation using shellscript and e.g. awk, but that would definitely be a bad choice of tools. I could write it in java if the main purpose of the project at hand was better suited to java. Or, I could write it in C or C++ if MD5 functionality was the core of the project, and I didn't want to depend on external libraries. But, let's not make this a flame war. You're just as entitled to your opinion as I am to mine, so let's just agree to disagree ;) - --Erik S.
