Package javax.json

Provides an object model API to process JSON.

The object model API is a high-level API that provides immutable object models for JSON object and array structures. These JSON structures are represented as object models using the Java types JsonObject and JsonArray. The interface javax.json.JsonObject provides a Map view to access the unordered collection of zero or more name/value pairs from the model. Similarly, the interface JsonArray provides a List view to access the ordered sequence of zero or more values from the model.

The object model API uses builder patterns to create and modify these object models. The classes JsonObjectBuilder and JsonArrayBuilder provide methods to create and modify models of type JsonObject and JsonArray respectively.

These object models can also be created from an input source using the class JsonReader. Similarly, these object models can be written to an output source using the class JsonWriter.

This package includes several classes that implement other JSON related standards: JSON Pointer, JSON Patch, and JSON Merge Patch. They can be used to retrieve, transform or manipulate values in an object model.
