ScriptEngine.name - The name of the procedure to be called.thiz - If the procedure is a member of a class
defined in the script and thiz is an instance of that class
returned by a previous execution or invocation, the named method is
called through that instance.args - Arguments to pass to the procedure. The rules for converting
the arguments to scripting variables are implementation-specific.ScriptException - if an error occurs during invocation of the method.NoSuchMethodException - if method with given name or matching argument types cannot be found.NullPointerException - if the method name is null.IllegalArgumentException - if the specified thiz is null or the specified Object is
