Is there a Java class that can be any Javascript object?

Question

I am looking for a java class that can represent a dynamic javascript object. This is so that I can navigate from and to Json, providing easy access to data. I would like this class to have access methods similar to what you would expect in a javascript object.

Preferences p = new Preferences(...);

p.getString("a");
p.getInteger("a");
p.getObject("a");

All of the above would pass to the appropriate type or return zero. Now the key part should be like this:

p.getString("a.b.c");
p.getString("a[0].b.d[1]");

Etc. Is there something already done that handles this?
