Java EE includes support for JSR 353 (Java API for JSON Processing), which provides an API to parse, transform, and query JSON data using two programming models – Object model and Streaming model. The Java API for JSON Processing contains the following packages which is used to parse, transform and query JSON data.

1. The javax.json package contains a reader interface (JsonReader), a writer interface (JsonWriter), and a model builder interface (JsonObjectBuilder) for the object model. This package also contains other utility classes and Java types for JSON elements.

2. The javax.json.stream package contains a parser interface (JsonParser) which represents an event based parser that can read JSON data from a stream model or from an object model and a generator interface (JsonGenerator) which can write JSON data to a stream one element at a  time.
