Hi!

We are currently dealing with a huge code base of generated Java.
The translation tool produces suboptimal Java in sevaral aspects.
Any information about Java code analysis and transformation tools
that are able to enhance the code in the aspects listed below would be
highly appreciated!

1. Automatically reduce scope of local variables

2. Combine declaration and instantiation of local variables where
possible

e.g.

    String s = null;

        ...

    s = "hello";

    -> ....

    String s = "hello";

3. Automatically reduce visibility of fields and methods.
    removing methods from an interface which are only sent by the
implementor would also be nice...

4. Give a list of methods with return value that is never used

5. Make parameters and locals final.

Cheers!
