Well not really. For example, errors you can do in C++ but not in Java:
    - Accidently use memory that has already been deleted but the
      pointer was not cleared.
    - Assign something out of bounds to some memory area: in Java
      pointer arithmetic is simply not possible. You cannot do things like
            *(a+100) = 10;
    - State and rogue pointers are simply NOT possible in Java.
      There is no way you can have a pointer to something that doesn't
      exist anymore.
