Method overloading: Two or more techniques with similar name stated within a class are said to be overloaded. This exerts to both constructors and other methods. The overloading applies via a class hierarchy, thus a sub class may overload a method stated in one of its super classes. This is significant to distinguish among an overridden method and an overloaded method. Overloaded methods should be distinguishable in some manner from each other; either by containing different numbers of arguments, or by the kinds of those arguments being different. Overridden methods contain similar formal arguments.
