Java Coding Problems

Using JSON-B

Java EE 8 comes with a JAXB-like, declarative JSON binding called JSON-B (JSR-367). JSON-B is consistent with JAXB and other Java EE/SE APIs. Jakarta EE takes Java EE 8 JSON (P and B) to the next level. Its API is exposed via the javax.json.bind.Jsonb and javax.json.bind.JsonbBuilder classes:

Jsonb jsonb = JsonbBuilder.create();

For deserialization, we use Jsonb.fromJson(), while, for serialization, we use Jsonb.toJson():

• Let's read melons_array.json as an Array of Melon:

Melon[] melonsArray = jsonb.fromJson(Files.newBufferedReader(  pathArray, StandardCharsets.UTF_8), Melon[].class);

• Let's read melons_array.json as a List of Melon:

List<Melon> melonsList   = jsonb.fromJson(Files.newBufferedReader( pathArray, StandardCharsets.UTF_8), ...
