What the title says.

Is there anyway (using Kafka Java API) to get the number of AVAILABLE Kafka brokers in a cluster?

I know that with the command line utility that comes with the Kafka server, this can be done; but I haven't found anything on how to do it using Java API.

You can get the broker's and cluster information from kafkaAdminClient.describeCluster

Get information about the nodes in the cluster, using the default options. This is a convenience method for #describeCluster(DescribeClusterOptions) with default options. See the overload for more details.

Properties properties = new Properties();
properties.setProperty("bootstrap.servers", "localhost:9092");
properties.setProperty("client.id", "producerAdmin");
properties.setProperty("metadata.max.age.ms", "3000");
kafkaAdminClient = AdminClient.create(properties);

DescribeClusterResult result = kafkaAdminClient.describeCluster()
KafkaFuture<Collection<Node>> nodes = result.nodes();

And you can use host,port methods in Node class to get more information
