Suppose I have two classes A and B. Both are identical (same atributes, methods, etc), but they are named different.
There’s some safe way, in Java, to cast a B object as an A object?

No, you cannot cast one to the other if they belong in different class hierarchies. They are not identical, even if they happen to share the same attributes and methods. Additionally, if they belong to the same class hierarchy, but one is not a superclass of the other, you can’t cast across the same class hierarchy either. There’s only upcasting and downcasting within a hierarchy.
However, you can pass objects of either class to a certain method if
(And that’s the basic premise of polymorphism.)
