The methods of all classes in java.util.concurrent and its subpackages extend these guarantees to higher-level synchronized. In particular: Actions in a threadprior to placing an object into any concurrent collectionhappen-beforeactions subsequent to the access or removal of that element from the co...
Java provides data collections that you can use in your concurrent programs without any problems or inconsistency. Basically, Java provides two kinds of collections to use in concurrent applications: Blocking collections: This kind of collection includes operations to add and remove data.If the operati...

所以高并发环境下尽量不要直接使用HashMap,对系统造成的影响很难排除。 和Collections.synchronizedMap(new HashMap(...))相比,外ConcurrentHashMap在高并发的环境下有着更优秀的吞吐量。因为ConcurrentHashMap可以支持写并发,基本原理是内部分段,分段的数量决定着并发程度。通过concurrencyLevel参数可以设置。如果你能预期并...
Thejava.util.concurrentpackage includes a number of additions to the Java Collections Framework. These are most easily categorized by the collection interfaces provided: BlockingQueuedefines a first-in-first-out data structure that blocks or times out when you attempt to add to a full queue, or ...
The Collections framework introduced iterators for traversing a list or other collection, which optimizes the process of iterating through the elements in a collection. However, the iterators implemented in thejava.utilCollections classes are fail-fast, which means that if one thread changes a collec...
