Redundant 'if' statement

Reports if statements that can be simplified to a single assignment, return, or assert statement.


if (foo()) { return true; } else { return false; }

After the quick-fix is applied:

return foo();

Locating this inspection


Can be used to locate inspection in e.g. Qodana configuration files, where you can quickly enable or disable it, or adjust its settings.

Via Settings dialog

Path to the inspection settings via IntelliJ Platform IDE Settings dialog, when you need to adjust inspection settings directly from your IDE.

Settings or Preferences | Editor | Inspections | Java | Control flow issues

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.
