Reference checked for 'null' is not used inside 'if'

Reports references to variables that are checked for nullability in the condition of an if statement or conditional expression but not used inside that if statement.

Usually this either means that the check is unnecessary or that the variable is not referenced inside the if statement by mistake.


void test(Integer i) { if (i != null) { // here 'i' is not used inside 'if' statement System.out.println(); } }
