 A method invocation ([§11.7.8.2](expressions.md#11782-method-invocations)) creates a copy, specific to that invocation, of the formal parameters and local variables of the method, and the argument list of the invocation assigns values or variable references to the newly created formal parameters. Within the *block* of a method, formal parameters can be referenced by their identifiers in *simple_name* expressions ([§11.7.4](expressions.md#1174-simple-names)).
