本文整理了Java中redis.clients.jedis.Jedis.zcard()方法的一些代码示例，展示了Jedis.zcard()的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。Jedis.zcard()方法的具体详情如下：
包路径：redis.clients.jedis.Jedis
类名称：Jedis
方法名：zcard

Jedis.zcard介绍

[英]Return the sorted set cardinality (number of elements). If the key does not exist 0 is returned, like for empty sorted sets.

Time complexity O(1)
[中]返回已排序的集合基数（元素数）。如果键不存在，则返回0，如空排序集。
时间复杂度O（1）
