public class UnnecessaryParenthesesCheck extends Check
Checks if unnecessary parentheses are used in a statement or expression. The check will flag the following with warnings:
return (x); // parens around identifier return (x + 1); // parens around return value int x = (y / 2 + 1); // parens around assignment rhs for (int i = (0); i < 10; i++) { // parens around literal t -= (z + 1); // parens around assignment rhs
The check is not "type aware", that is to say, it can't tell if parentheses are unnecessary based on the types in an expression. It also doesn't know about operator precedence and associatvity; therefore it won't catch something like
int x = (a + b) + c;
In the above case, given that a, b, and c are
all int
variables, the parentheses around a + b
are not needed.
