I am using AdminClient to alter other configurations of existing kafka topic. But I cannot find a method to change the replication factor of the topic. Is there any way that I can change the replication factor using java?

apache-kafka java

This is currently not possible using the AdminClient. However there is a KIP in progress, KIP-455, that will add that functionality soon.

At the moment, the recommended way to change the replication factor of a topic is to use the kafka-reassign-partitions.sh tool, see this section in the docs.
