== Why is this an issue?

In Java 21 the `java.lang.Math` class was updated with the static method `Math.clamp`, to clamp a numerical value between a min and a max value.

Using this built-in method is now the preferred way to restrict to a given interval, as it is more readable and less error-prone.

== How to fix it

Replace your clamp method implementation with the `Math.clamp` method.

=== Code examples

==== Noncompliant code example

[source,java,diff-id=1,diff-type=noncompliant]
----
int clampedValue = value > max ? max : value < min ? min : value; // Noncompliant; Replace with "Math.clamp"
----

[source,java,diff-id=2,diff-type=noncompliant]
----
int clampedValue = Math.max(min, Math.min(max, value)); // Noncompliant; Replace with "Math.clamp"
----

==== Compliant solution

[source,java,diff-id=1,diff-type=compliant]
----
int clampedValue = Math.clamp(value, min, max);
----

[source,java,diff-id=2,diff-type=compliant]
----
int clampedValue = Math.clamp(value, min, max);
