java.util.Collections集合工具类,用来操作集合对象的元素方法如下: public static <T> boolean addAll(Collection<? super T> c,T...elements);往集合中一次性添加多个元素 public static <T> void shuffle(List<?> list);打乱集合中的元素顺序 public static <T> void sort(List<T> list);将集合中的元素...

LinkedHashMapis a Hash table and linked list implementation of the Map interface, with predictable iteration order. This implementation differs from HashMap in that it maintains a doubly-linked list running through all of its entries. This linked list defines the iteration ordering, which is normal...

LinkedList/ArrayList 非线程安全,不能用于并发场景(List的方法支持栈和队列的操作,因此可以用List封装成stack和queue) Collections.synchronizedList 使用wrapper class封装,每个方法都用synchronized(mutex:Object)做了同步 LinkedBlockingQueue 采用了锁分离的设计,避免了读/写操作冲突,且自动负载均衡,可以有界。BlockingQueue...

我不知道Spring是如何推断我试图注入的映射是org.apache.commons.collections.map.LinkedMap类型的。我怎样才能解决这个问题?将org.apache.commons.collections.map.LinkedMap转换为属性‘异步连接Cannot’所需的类型java.util.LinkedHashMap;嵌套异常为java.lang.IllegalArgumentException:无法将org.apache.commons.collectio ...
Vector,Collections.synchronizedList(List<T> list), ConcurrentLinkedQueue等 ConcurrentLinkedQueue实现的数据结构? ConcurrentLinkedQueue底层原理? 全程无锁(CAS) ConcurrentLinkedQueue的核心方法有哪些? offer(),poll(),peek(),isEmpty()等队列常用方法 说说ConcurrentLinkedQueue的HOPS(延迟更新的策略)的设计?
