decompiling class, jar & native executables?

[Sue]

I an rather new to java programming and just found out that compiled
java class and jar files can be easily decompiled to reveal the source
code!

Is it equally easy to decompile 'native' java code or, could making a
native executable be an alternative to an obfisticator?

Thank you very much for all help!

.. an alternative to an obfisticator?

Ouch! Yes, hopefully.

I suspect you mean 'Obfuscator'
