Anybody here know about java collections
A collection represents a group of objects, known as its elements. Some collections allow duplicate elements and others do not. Some are ordered and others unordered. The most used kind of collections are subinterfaces like Set and List. When building your software you must choose which one fits better to the objective.
Please help, any idea?
