You can instantiate a PulsarClient object using just a URL for the target Pulsar cluster like this:
PulsarClient client = PulsarClient.builder() .serviceUrl("pulsar://localhost:6650") .build();
If you have multiple brokers, you can initiate a PulsarClient like this:
PulsarClient client = PulsarClient.builder() .serviceUrl("pulsar://localhost:6650,localhost:6651,localhost:6652") .build();
:::note
If you run a cluster in standalone mode, the broker is available at the pulsar://localhost:6650
URL by default.

For detailed client configurations, see the reference doc.
