1. ArrayList _vs. Linked List _vs. Double Linked List (1) ArrayList - ArrayList : https://opentutorials.org/module/1335/8709 Array List는 배열을 이용해서 리스트를 구현한 것을 의미합니다. 장점은 내부적으로 배열을 이용하기 때문에 인덱스를 이용해서 접근하는 것이 빠릅니다. 하지만 데이터의 추가와 삭제가 느립니다. - ArrayList - Java 구현 : https://opentutorials.org/module/1335/8715 - [Java] 자바의 자료구조 - ArrayList, Stack : https://onsil-thegreenhouse.github.io/programming/java/2018/02/18/java_tutorial_1-22/ (2) Linked List 자료구조: Linked List 대 ArrayList : http://www.nextree.co.kr/p6506/ LinkedList 는 무한 개수의 자료를 삽입할 수 있다. ArrayList 는 사이즈가 고정되어 있기 때문에 삽입 시 사이즈를 늘려주는 연산이 추가되어야 한다. ArrayList 는 삭제 시 순차적인 인덱스 구조로 인해서 삭제된 빈 인덱스를 채워야 하기 때문에 채워주는 연산이 추가 되어야 한다. LinkedList 는 채우는 작업 없이 주소만 서로 연결시켜 주면 되기 때문에 추가/삭제가 ArrayList 보다 빠르고 용이하다. 삽입 / 삭제가 빈번하게 발생하는 프로세스의 경우 LinkedList 를 사용하여 시스템을 구현하는 것이 바람직하다. ArrayList 에서는 무작위 접근 ( Random Access ) 이 가능 / LinkedList 에서는 순차접근 ( Sequential Access ) 만 가능하다. (3) Doubly Linked List Doubly linked list - Java 구현 - https://opentutorials.org/module/1335/8941 (4) Singly Linked List vs Doubly Linked List [자료구조] Java 단순 연결 리스트(simple linked list) 정리 - http://hyeonstorage.tistory.com/259 [자료구조] Java 이중 연결 리스트 (doubly linked list) 정리 - http://hyeonstorage.tistory.com/261 2. Stack _vs. Queue Difference Between Stack and Queue - https://techdifferences.com/difference-between-stack-and-queue.html Stack - https://terms.naver.com/entry.nhn?docId=2837556&cid=40942&categoryId=32841 Queue - https://terms.naver.com/entry.nhn?docId=834442&cid=42344&categoryId=42344 Stack과 Queue - http://tcpschool.com/java/java_collectionFramework_stackQueue Stack - Class , Queue - Interface 3. HashMap _vs. HashTable Map 컬렉션 클래스 - http://tcpschool.com/java/java_collectionFramework_map 6 Difference Between HashMap And HashTable : Popular Interview Question In Java With Example - https://javahungry.blogspot.com/2014/03/hashmap-vs-hashtable-difference-with-example-java-interview-questions.html (1) HashMap 은 비동기, Not Thread Safe. (2) HashMap 은 key 에 하나의 null 만 허용, value 는 여러개의 null 허용 HashTable 은 key 와 value 에 null 을 허용하지 않음 (3) HashMap object values are iterated by using iterator .Hashtable is the only class other than vector which uses enumerator to iterate the values of Hashtable object. (4) Fail-fast iterator : The iterator in HashMap is fail-fast iterator while the enumerator for Hashtable is not. Hashmap 의 iterator 는 fail-fast iterator 라면 Hashtable 의 enumerator 는 fail-fast iterator 가 아니다. 오라클 문서에 따르면, iterator 가 생성된 후 iterator 자신의 제거 메소드를 제외하고는 Hashtable 이 구조적으로 수정되면 iterator 는 ConcurrentModification Exception 을 throw 한다. Structural modification means adding or removing elements from the Collection object (here HashMap or Hashtable) . 구조적인 수정이란 Collection (hashtable, hashmap) 객체에서 요소들을 추가하거나 제거한다는 것을 의미한다. Thus the enumerations returned by the Hashtable keys and elements methods are not fail fast.We have already explained the difference between iterator and enumeration. (5) 성능 : HashMap 은 unsynchronized 이기 때문에 훨씬 빠르고 적은 메모리를 사용한다. Unsynchronized 객체들이 보통 단일 스레드 환경에서의 Hashtable 같은 synchronized개체에 비해 성능상 더 낫다. (6) Superclass and Legacy : Hashtable 은 현재 JDK 1.7 에서 잘 사용되지 않는 Dictionary 서브 클래스이다. 더이상 사용되지 않는다. It is better off externally synchronizing a HashMap or using a ConcurrentMap implementation (e.g ConcurrentHashMap).HashMap is the subclass of the AbstractMap class. Although Hashtable and HashMap has different superclasses but they both are implementations of the "Map" abstract data type. When to use HashMap and Hashtable? https://javahungry.blogspot.com/2014/03/hashmap-vs-hashtable-difference-with-example-java-interview-questions.html 1. Single Threaded Application HashMap should be preferred over Hashtable for the non-threaded applications. In simple words , use HashMap in unsynchronized or single threaded applications . 2. Multi Threaded Application We should avoid using Hashtable, as the class is now obsolete in latest Jdk 1.8 . Oracle has provided a better replacement of Hashtable named ConcurrentHashMap. For multithreaded application prefer ConcurrentHashMap instead of Hashtable. HashMap Hashtable Synchronized No Yes Thread-Safe No Yes Null Keys and Null values One null key ,Any null values Not permit null keys and values Iterator type Fail fast iterator Fail safe iterator Performance Fast Slow in comparison Superclass and Legacy AbstractMap , No Dictionary , Yes 4. TreeMap _vs. TreeTable http://rangken.github.io/blog/2015/java.map/ https://onsil-thegreenhouse.github.io/programming/java/2018/02/22/java_tutorial_1-24/ TreeMap 은 key 를 기준으로 정렬할때 유용 (1) 성능면에서는 HashMap (2) 정렬은 TreeMap (3) 입력순서는 LinkedHashMap 5.
