Description
It is generally a bad practice to catch NullPointerException.
Programmers typically catch NullPointerException under three circumstances:
- The program contains a null pointer dereference. Catching the resulting exception was easier than fixing the underlying problem.
- The program explicitly throws a NullPointerException to signal an error condition.
- The code is part of a test harness that supplies unexpected input to the classes under test.
Of these three circumstances, only the last is acceptable.
Risk Factors
TBD
Examples
The following code mistakenly catches a NullPointerException.
try { mysteryMethod(); } catch (NullPointerException npe) { }
