Usage

Read JSON

var data = """
{
    "message": "Hello World!",
    "targets": ["WORLD", "UNIVERSE"],
    "size": 42,
    "seen": true
}
""";

var json = Json.read(data).asObject();

System.out.println(json.get("message").asString());

for (var t : json.get("targets").asList()) {
    System.out.println(t.asString());
}

System.out.println(json.get("size").asInt());
System.out.println(json.get("seen").asBoolean());

Output

Hello World!
WORLD
UNIVERSE
42
true

Write JSON (Pretty)

var object = new JsonObject();

object.put("message", "Hello World!");
object.put("targets", List.of("WORLD", "UNIVERSE"));
object.put("size", 42);
object.put("seen", true);

System.out.println(Json.write(object));

Output

{
  "message": "Hello World!",
  "targets": [
    "WORLD",
    "UNIVERSE"
  ],
  "size": 42,
  "seen": true
}

Write JSON (Normal)

var object = new JsonObject();

object.put("message", "Hello World!");
object.put("targets", List.of("WORLD", "UNIVERSE"));
object.put("size", 42);
object.put("seen", true);

System.out.println(Json.write(object));

Output

{"message": "Hello World","targets": ["WORLD","UNIVERSE"],"size": 42,"seen": true}
