Clamp function can be used

Reports combinations of Math.max() and Math.min() that are equivalent to Math.clamp().

Example:

int min = 5, max = 10;
/*before*/ input = Math.max(Math.min(max, input), min);
/*after*/  input = Math.clamp(input, min, max);

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.

MathClampMigration

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.

By default, the inspection only shows when it can statically prove that min is lesser or equal than max. This is done to avoid any IllegalArgumentException due to semantics changes. If you want the inspection to show up nonetheless, you can enable the Warn even if the lower bound could be higher than the upper bound option.

This inspection depends on the Java feature 'Clamp methods in standard library', which is available since Java 21.
