You can use Serialization.asYaml() method to convert object to YAML string and Serialization.asJson() method to convert object to JSON string:

I've tested this code on KubernetesClient v6.7.2 and it seems to be working okay:

try (KubernetesClient k8s = new KubernetesClientBuilder().build()) {
  Pod pod = k8s.pods()
      .inNamespace("default")
      .withName("excj496")
      .get();
  // Get YAML string
  System.out.println(Serialization.asYaml(pod));
  // Get JSON string
  System.out.println(Serialization.asJson(pod));
}
