Getting the version of Memcached server can be useful while debugging or for logging purposes. It helps developers ensure that they are using a compatible version, and keep track of the server status.
Java Memcached client libraries like Xmemcached and Spymemcached provide ways to get the Memcached server version. Here are examples for each:
In this code, we first create a
XMemcachedClientBuilder with the address of the Memcached server. Using the builder, we create a
MemcachedClient, which is used to interact with the server. The
getVersions() method retrieves the version for all connected Memcached servers.
In this code, we create a
MemcachedClient with the server address. The
getStats() method retrieves statistics from all connected Memcached servers which includes the version.

IOExceptions. Networking operations are always prone to exceptions, so always include adequate exception handling.
1. How can I connect to a Memcached server running on a different machine?
You can replace 'localhost' in the examples above with the IP address or hostname of the machine where Memcached server is running.
2. What if my application connects to multiple Memcached servers?
getStats() methods return information for all connected servers. You can iterate over the returned map to get data for each server.
