SequenceBarrier uses the waitFor method when the consumer's speed is greater than the producer's production speed, the consumer can give the producer a certain buffer time through the waitFor method, coordinate the speed of the producer and the consumer, and waitFor execution timing: Sequencer is ...
Map是一个用于存储 Key-Value 键值对的集合类,也就是一组键值对的映射,在Java中Map是一个接口,是和Collection接口同一等级的集合根接口; 存储结构 上图看起来像是数据库中的关系表,有类似的两个字段,KeySet(键的集合)和 Values(值的集合),每一个键值对都是一个Entry; 特点 没有重复的 key; key 用set保存...
