27
* sVariableName - a static class level member variable
28
* variableName() - accessor for a class member (no 'get' in front of name)
29
* setVariableName() - mutator for a class member (prefix with 'set')
31
* Additional useful conventions:
33
* theVariableName - a method parameter (prefix with 'the')
34
* myVariableName - a locally declared variable within a method ('my' prefix)
36
* DO: Use mixed case variable names - myVariableName
37
* DON'T: separate variable names using underscores: my_variable_name (NO!)
