Java Collections Framework
14 April 2021OSU CSE1
Overview
The Java Collections Framework (JCF)
is a group of interfaces and classes similar to the OSU CSE componentsThe similarities will become clearly evident
from examplesSee Java libraries package java.util
There are some important differences, too,
however, that deserve mention (at the end)14 April 2021OSU CSE2

Map.Entryin the JCF is
very similar to Map.PairExample: Map m
14 April 2021OSU CSE15
CodeState
m = {("PB", 99), ("BK", 42), ("SA", 42)}Sets =
m.keySet(); m = {("PB", 99), ("BK", 42), ("SA", 42)} s = {"SA", "BK", "PB"} Example: Map m
14 April 2021OSU CSE16
CodeState
m = {("PB", 99), ("BK", 42), ("SA", 42)}Sets =
m.keySet(); m = {("PB", 99), ("BK", 42), ("SA", 42)} s = {"SA", "BK", "PB"} Note all the aliases here!
There is no problem in this case
because Stringis immutable, but consider the potential problems if it were not.14 April 2021OSU CSE17
CodeState
m = {("PB", 99), ("BK", 42), ("SA", 42)}Collectionc =
m.values(); m = {("PB", 99), ("BK", 42), ("SA", 42)} c = {42, 99, 42} Example: Map m

A view is backed by the underlying
collection, which means that if the view is collection is also modified, and vice versa See Javadocfor supported modifications
Be especially careful when iterating over a
view of a collection and trying to modify it 14 April 2021OSU CSE19
Example: List s
14 April 2021OSU CSE20
CodeState
s = <10,7, 4, 2> s.subList(1,3).clear(); s = <10, 2> 14 April 2021OSU CSE21
CodeState
m = {("PB", 99), ("BK", 42), ("SA", 42)} m.values().remove(42); m = {("PB", 99), ("SA", 42)} Example: Map m
14 April 2021OSU CSE22
CodeState
m = {("PB", 99), ("BK", 42), ("SA", 42)} m.values().remove(42); m = {("PB", 99), ("SA", 42)} Example: Map m
Because removefor
Collection(assuming it is
supported for m.values!) removes one copy, we do not know which pair remains in m. Could removeCause Trouble?
The object (dynamic) type of
m.values()in the above code might be an implementation of Listor of Queue But not of Set; why not?
Could the optionalremovemethod not
be supported by the object type of m.values()? 14 April 2021OSU CSE23

Yes! But only when the backing Map does not support remove(). Otherwise, it is supported because the informal Javadoc for the valuesmethod says: removes the corresponding mapping from the map, via the Iterator.remove, Collection.remove, removeAll, retainAlland clearoperations. It does not support the addor addAll Iterating Over a Map
Because Mapdoes notextend Iterable,
but Collection(hence Set) does extend Iterable, you can (only) iterate over a Mapusing one of its three views: Keys: Set keySet()
Values: Collection values()
