Basically my question should be put this way, how to produce binary executable of java? I am going to a java forum, thanks for your help!

Sweeping generalizations like that are never entirely true. Some versions of Java have a very good optimizer these days, and can compile parts of itself into native assembly; in rare circumstances it's possible for it to outperform C in a tight loop. I was quite surprised.

Of course they do -- being written in C, they get converted directly to assembly language.

That doesn't mean they're not interpreted languages. Try writing a perl interpreter, in perl, you will get slowdown because of the extra layer of interpretation.

Java programs are run a bit differently than C; they are compiled into Java bytecode, not machine code.
You write your code in a text file with extension ".java". (The file name must be the same as the public class name in the program.) So if the file name is "Hello.java", you compile it using the "javac" compiler -

Code:
javac Hello.java

This creates a binary file called "Hello.class" in the same directory as Hello.java. You then feed this class file to the JVM -

Code:
java Hello.class

and it runs your program.
