method overloading

Two or more methods with the same name defined within a class are said to be overloaded. This applies to both constructors and other methods. Overloading applies through a class hierarchy, so a sub class might overload a method defined in one of its super classes. It is important to distinguish between an overloaded method and an overridden method. Overloaded methods must be distinguishable in some way from each other; either by having different numbers of arguments, or by the types of those arguments being different. Overridden methods have identical formal arguments.
