{"Image DocumentName": "Concrete collections in Java library", "Image ImageDescription": "ArrayList: indexed sequence that grows/shrinks dynamically. LinkedList: ordered sequence that allows efficient insertions and removal at any location. HashSet: unordered collection that rejects duplicates. TreeSet: sorted set. EnumSet: set of enumerated type values (implements Set) LinkedHashSet: set that remembers the order in which elements were inserted. PriorityQueue: allows efficient removal of the smallest element. HashMap: stores key/value associations. TreeMap: map in which the keys are sorted. EnumMap: keys belong to an enumerated type (impl. Map) LinkedHashMap: remembers the order in which added. WeakHashMap: keys and entries that can be reclaimed by the garbage collector if the keys are not used elsewhere. IdentityHashMap: keys that are compared by ==, not equals.", "Image XResolution": "37", "Image YResolution": "37", "Image ResolutionUnit": "Pixels/Centimeter", "Image Software": "SlidePlayer", "Image YCbCrPositioning": "Centered"}
