Java EE 7 Application Developer — Question 38

Which class do you use to handle an incoming JSON Message as a stream?

Answer options

• A. JsonReader
• B. JsonObjectBuilder
• C. JsonParser
• D. JsonObject

Correct answer: A

Explanation

The correct answer is JsonReader, as it is specifically designed to read JSON data in a streaming fashion. JsonObjectBuilder is used for constructing JSON objects, JsonParser is for parsing JSON into a tree structure, and JsonObject represents a JSON object in memory, making them unsuitable for handling incoming JSON messages as streams.
