'if' statement can be replaced with conditional or boolean expression

Reports if statements that can be replaced with conditions using the &&, ||, ==, !=, or ?: operator.

The result is usually shorter, but not always clearer, so it's not advised to apply the fix in every case.

Example:

if (condition) return true; else return foo;

After the quick-fix is applied:

return condition || foo;

Locating this inspection

By ID

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

SimplifiableIfStatement

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 | Code style issues

Configure the inspection:

Use the Don't suggest '?:' operator option to disable the warning when the ?: operator is suggested. In this case, only &&, ||, ==, and != suggestions will be highlighted. The quick-fix will still be available in the editor.
Use the Ignore chained 'if' statements option to disable the warning for if-else chains. The quick-fix will still be available in the editor.
