JSON Collectors are useful when working with streams and filtering a JsonArray with a results into another JsonArray. In the example below you are filtering for a female gender and creating a JsonArray with all the selected names.
Raw
JsonSample.java
JsonArray contacts = ...;
JsonArray femaleNames =
contacts.getValuesAs(JsonObject.class).stream()
.filter(x->"F".equals(x.getString("gender")))
.map(x->(x.getString("name"))
.collect(JsonCollectors.toJsonArray());
