thank you very much

So what google searches have you done so far?

i searched but i couldn`t find a good one.There are some jvm s with lots of code files which are not that much simple.please some body help.

Here's an idea - list the ones you found, and explain what it is you don't like about them.

There is no point us repeating your searches, for us to post "what about this one" for you to turn round and say "no, looked at that one already".

Have a look at this:

Bundling a minimal 'bare bones' JVM with your Application - Vincent Liu

The idea is that, like any other library made of parts, you can strip it down to a functioning minimum. Ie, you don't need a "small jvm implementation", you just need to take your regular old implementation and leave out the parts you don't need.

Apparently the JVM on the Mars rovers used < 200mb, which is like half of what it appears to use on my laptop with eclipse running. I guess they didn't need an IDE in space :D
