What is the `ZookeeperClient` class used for in Java?
The `ZookeeperClient` class is used to maintain connections between the client and the ZooKeeper ensemble, providing methods to perform basic operations.
Thatâ€™s a good explanation, but the `ZookeeperClient` class is more specific to higher-level ZooKeeper operations, such as session management and coordination.
Can you explain how the `ZookeeperClient` class handles session expiration and reconnecting?
