Notes

Module 7

  • An inner nested class can reference non-static instance methods
    and fields.
  • A static nested class cannot reference non-static instance methods
    and fields.
  • Any code can report an exception via “throw”.
  • Methods declaring checked exceptions require callers to
    provide an exception handler.
  • The virtual machine searches up the runtime call stack to find
    exception handler.
