        AggregationBuilders
                .avg("agg")
                .field("height");

[source,java]
--------------------------------------------------
import org.elasticsearch.search.aggregations.metrics.avg.Avg;
--------------------------------------------------

[source,java]
--------------------------------------------------
// sr is here your SearchResponse object
Avg agg = sr.getAggregations().get("agg");
double value = agg.getValue();
