Hide things in Java

Question

I wanted to make a Java Project with a SQL Database and the connection inside the jar. Problem is how can I hide/or else do it that no one will see connection information like the password if he decompiles it.
Thanks in before.

Answer 1

If someone can decompile youre code he can see anything you have done. And he can see how you want to hide something.
So there is no way to hide something if a code is decompiled an analysed.
