Collections are like containers that group multiple items in a single unit. for example, a jar of chocolates, a list of names, etc. collections are used in every programming language and when java arrived, it also came with few collection classes – vector, stack, hashtable, array. java 1.2 provided collections framework that is the.

Typical operation: get an element by its id (where id is of any type, not only int as in case of list). the differences. set vs. map: in set you search data by themselves, whilst in map by their key. n.b. the standard library sets are indeed implemented exactly like this: a map where the keys are the set elements themselves, and with a dummy value.
