Is told everythig about Java but

Object exists inside classes, there no one outside, or exist an exception? even when you don't create a class is a class that already exists inside the Java? People explain but don't say, people think that know but aren't sure. Rute Bezerra de Menezes Gondim

Ps.: When you try figure out what is class and what is object you aren't relizing that objects only exixts inside classes.
