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

Jar files usually only include .class files, which are java bytecode files, as well as resources. However, to be a little more secure about your code, you'll want to turn off debugging information and if you really want to be secure, run it through an obfuscator.

Edit: berry120's comment is right - they can contain source files, but usually they do not. I just want to clarify for any future readers of this. It depends on the settings of the tool you use to generate the jar.
