Redundant 'if' statement
Reports if
statements that can be simplified to a single assignment, return
, or assert
statement.
Example:
if (foo()) {
return true;
} else {
return false;
}
After the quick-fix is applied:
return foo();

Can be used to locate inspection in e.g. Qodana configuration files, where you can quickly enable or disable it, or adjust its settings.
RedundantIfStatement
Configure the inspection:
Use the Ignore chained 'if' statements option if you want to hide a warning for chained if
statements.
For example, in the following code the warning will be hidden, but the quick-fix will still be available:
if (condition1) return true;
if (condition2) return false;
return true;
Note that replacing if (isTrue()) assert false;
with assert isTrue();
may change the program semantics when asserts are disabled if condition has side effects. Use the Ignore 'if' statements with trivial 'assert' option if you want to hide a warning for if
statements containing only assert
statement in their bodies.
Here you can find the description of settings available for the Redundant 'if' statement inspection, and the reference of their default values.
