Hi everybody.
I'm working about 1.5 years on C#.NET , I'm not an expert but I'm OK.
I'm working on image processing most of the time these days.
Now I wanna know , Is there any a advantage in Java compared with C# ?
Is it essential to know Java ?
Many Thanks in advance.

This is most discussed topic. Here[^] is one for instance. The only advantage I am seeing for JAVA is it's portability.

That of course is subjective.
If you just want to learn another language just for the knowledge and perhaps for employment benefit then learn SQL. SQL is different enough from C#/Java that learning it requires work. And it is useful in most businesses.

Be specific, which errors do you have, where are you stuck, ... ?
Anyway, the code you pasted doesn't make any sense (misplaced braces, no name for the class, no body for the main function, all the code is in your class and not in a function, ...). If this is your real code (but I can hardly imagine this), then nobody here will be able to help you: you are lacking the most basic skills in Java. I suggest you start from the begining: learn the syntax (from a good book, it is always the best).

If it compiles then I suggest you Debug it line by line because there may be a problem with your logic.

What's the best solution for doing non blocking sockets in Java? The Socket class in and of itself doesn't support this. I'm aware of NIO but have heard rumors that's not very good or perhaps tricky to use?
I found Apache's MINA (http://mina.apache.org[^]) which looks promising, but wondered what people here have used.

Jim,
the easiest is to create the ServerSocket listening on it's own thread. The listening thread is blocked, but you can still call the close() method.
This will cause a SocketException to be thrown on the listening thread to allow for graceful exit.
See Class:ServerSocket[^] for details.
Panic, Chaos, Destruction.
My work here is done.

Have you actually researched anything?
Anyway, look at BufferedImage.[^]
If you can't find what your looking for on there then you should choose something else to do.

what would be the use of the strong tokenizer?

It breaks a sentance into words, is a simple way of putting it.
Have a look at the Documentation.[^]
