public class IndexedList

extends java.util.ArrayList

A List that keeps an index of its contents. Sort of like a sorted set or a map or an EntryList. CAN'T implement both Map and List. Why? Because remove() has two different return types... IndexedList.java:5: The method boolean remove(java.lang.Object) declared in class java.util.AbstractCollection cannot override the method of the same signature declared in interface java.util.Map. They must have the same return type.
