java集合及concurrent并发包 集合包 集合包最常用的有Collection和Map两个接口的实现类,Colleciton用于存放多个单对象,Map用于存放Key-Value形式的键值对。 Collection中最常用的又分为三种类型的接口:List、Queue和Set,List和Set最明显的差别为List支持放入重复的元素,而Set不支持。 List最常用的实现类有:ArrayList、Link...

用于多线程上下文中的 Collection 实现:ConcurrentHashMap、ConcurrentSkipListMap、ConcurrentSkipListSet、CopyOnWriteArrayList 和 CopyOnWriteArraySet。 当期望许多线程访问一个给定 collection 时,ConcurrentHashMap 通常优于同步的 HashMap,ConcurrentSkipListMap 通常优于同步的 TreeMap。 当期望的读数和遍历远远大于列表的更新...
在遍历Java容器(ArrayList, LinkedList, HashSet, TreeSet, HashMap, HashTable)过程中不允许向该容器中Add/Remove元素, 否则会抛出ConcurrentModificationException 但在Java 1.5版本以来, Java类库就提供了一个并发集合(Concurrent collection) CopyOnWriteArrayList, CopyOnWriteArraySet, ConcurrentHashMap, 这是专门为解决死...
Java中Consumer类型的参数 java concurrent collection 1.JDK1.4及之前 在JDK1.4及之前的版本,主要提供的并发技术有: synchronized关键字 volatile关键字 不变模式 :不变模式,就是指:在并发编程中,为确保数据的一致性和正确性,使用一种不可改变的对象。依靠其不可变的性质,来确保在没有同步的情况下依旧保持一致性和...

{@code listIterator} methods are fail-fast: if the list is * structurally modified at any time after the iterator is created, in * any way except through the Iterator's own {@code remove} or * {@code add} methods, the iterator will throw a {@link * ConcurrentModificationException}....
