- Casting to void* and Back to Original_Data_Type*
Casting to void* removes all type safety If you use reinterpret_cast or static_cast to cast from a pointer type to void* and back to the same pointer type, you are actually guaranteed by the standard that the result will be well-defined
- Casting objects in Java - Stack Overflow

- c++ - What does casting to `void` really do? - Stack Overflow

- Does Java casting introduce overhead? Why? - Stack Overflow
For casting to a class type, it is known exactly how many superclasses there are until you hit java lang Object, so the type can be read at a constant offset from the type pointer (actually the first eight in HotSpot) Again this is analogous to reading a method pointer for a virtual method
