# HostProviderFactory: New factory class that checks connection strings and instantiates appropriate HostProvider
 ** DNS SRV format (e.g., "_zookeeper._tcp.example.com") → DnsSrvHostProvider
 ** Traditional format (e.g., "server1:2181,server2:2181") → StaticHostProvider
 # ConnectStringParser Enhancement: Extended to detect and validate DNS SRV connection string formats
 # ZooKeeper Constructor Integration: Updated ZooKeeper constructors to use HostProviderFactory for automatic provider creation

> Enhance ZooKeeper Java client to automatically detect connection string format and select appropriate HostProvider, enabling zero-code-change migration from static to DNS SRV-based service discovery.
> Following ZOOKEEPER-4956, applications must explicitly choose between StaticHostProvider and DnsSrvHostProvider. This ticket enables automatic provider selection based on connection string format, allowing seamless migration without code changes.
