Can i write java code in eclipse and send it to my arduino? Will it work or can arduino only read c and c++ code? I KNOW that the uC do not read code as we do, the uC read binary code.
No, you cannot use Java.
Didn't you like the answer last time you asked?
But i have Heard that some did use java for arduino. So C or C++ is the only choise?

You heard wrong.

What you might have heard is that the IDE is written in Java. The toolchain uses C++, with some funky pre-processing.
The toolchain is C too.
