I am running into this problem, and very confused. It seems there are two different libraries I can use.

One is com.google.cloud.bigquery where I see it from this source: https://cloud.google.com/bigquery/docs/reference/libraries#client-libraries-usage-java

The other one is com.google.api.services.bigquery where I see it from this source: https://github.com/googlearchive/bigquery-samples-java/blob/master/src/main/java/com/google/cloud/bigquery/samples/BigQueryJavaGettingStarted.java

The problem I am trying to solve is to set a destination table for the query. Most online QAs point me to use the second source. I followed the first source to set it up, and I am able to connect to the Bigquery now. The only problem is I cannot find a way to set the destination table.

I am super confused about these two libraries, and hope to have some explanations. Thanks!
