Java List of arguments

The argument list sets out what information we send to the method. As you may have guessed, this information-as anything else in Java-takes the form of objects. Therefore, we must specify the type of object to pass in the argument list, and the name of each object. As we do with objects elsewhere in Java, we actually p
