Answer
Predefined oracle exceptions
These are the PL/SQL runtime engine raised named system exceptions.
These exceptions are raised automatically by the program. You cannot control
when PL/SQL will raise a system exception.
User-defined exceptions
These are programmer raised named exceptions. The programmer can use an
explicit call to the RAISE statement to raise a programmer-defined or
system-named exception. The programmer can also raise unnamed,
programmer-defined exceptions and re-raised "current" exceptions.
