Answer 1

Using new Java API Client:

var countRequestResponse = client.count(CountRequest.of(c -> c.index("idx_name")));
System.out.println(countRequestResponse.count());

Using Java High Client Library

var countRequest = new CountRequest();
countRequest.indices("idx_name");
var response = getClient().count(countRequest, RequestOptions.DEFAULT);
System.out.println(response.getCount());
