Answer 1

I used the AdminClient api.

Properties properties = new Properties();
properties.put("bootstrap.servers", "localhost:9092");
properties.put("connections.max.idle.ms", 10000);
properties.put("request.timeout.ms", 5000);
try (AdminClient client = KafkaAdminClient.create(properties))
{
    ListTopicsResult topics = client.listTopics();
    Set names = topics.names().get();
    if (names.isEmpty())
    {
        // case: if no topic found.
    }
    return true;
}
catch (InterruptedException | ExecutionException e)
{
    // Kafka is not available
}
