How to save image from computer client to server using java?? Give me the source code..

"give me the code" is NEVER a good way to start.

At the very least be polite and ask nicely.

As said, there are many examples of how to do this, and many scenarios to think of that would lead to different ones depending on how the images actually arrive on the server.

I've implemented it several times, and am not going to give you any code both because of your attitude but also because said code is not mine to give away but belongs to my employers.

Quite often you can do it in just a few lines of code.
