`MethodParametersAttribute` is a preview API of the Java platform.
Programs can only use `MethodParametersAttribute` when preview features are enabled.
Preview features may be removed in a future release, or upgraded to permanent features of the Java platform.
Models the `MethodParameters` attribute 4.7.24, which can appear on methods, and records optional information about the method's parameters. Delivered as a `MethodElement`PREVIEW when traversing the elements of a `MethodModel`PREVIEW.

The attribute does not permit multiple instances in a given location. Subsequent occurrence of the attribute takes precedence during the attributed element build or transformation.

The attribute was introduced in the Java SE Platform version 8.
