Null pointer exception

/nʌl ˈpɔɪntər ɪkˈsepʃən/ noun

Definition

A runtime error that occurs when a program attempts to use a reference that points to no location in memory (null), typically causing the program to crash or throw an exception.

Etymology

Null comes from Latin 'nullus' meaning nothing. The concept was formalized by Tony Hoare in 1965, who later called it his 'billion-dollar mistake' due to the countless bugs and crashes it has caused.

Kelly Says

Tony Hoare, who invented null references, called them his 'billion-dollar mistake' because of all the crashes they've caused - and he's probably being modest about the cost! It's like trying to call someone when you don't actually have their phone number.
