Jar File - Prevent Access to Source Code

Question

I want to hand over a small Java app as a runnable jar but I do not want anybody to have access to my source code. Am I right in presuming that there is no source code (.jav

Answer 1

The .jar file does not include source code, only the bytecode (.class). But as the byte code is machine independent, it can be decompiled very easily. There is no way to prevent others to access your source code.
