TinyJson

TinyJson is a json data parser library for Java.
The parser is well tiny, very suitable for temporary use or small projects.

Summary

It's small and faster than org.json
Lets get started!

  1. Usage
  2. Download
  3. Methods

Usage

JsonObject

Creat a JsonObject

JsonObject jsonObject = new JsonObject();

Parse JsonObject, and get value

String rawData = "{\"Hello\":\"World\", \"age\":17}";
JsonObject result = new JsonObject(rawData);
System.out.println(result.getString("Hello"));
System.out.println(result.getInt("age"));

Get ListedJsonObject length

ListedJsonObject listedJsonObject = new ListedJsonObject("{\"Hello\":\"World\"}");
System.out.println(listedJsonObject.length);

JsonArray

Creat a JsonArray

JsonArray jsonArray = new JsonArray();

Parse jsonArray, and get value

String rawData = "[\"Hello\", \"World\", 17]";
JsonArray result = new JsonArray(rawData);
System.out.println(result.getString(0));
System.out.println(result.getString(1));
System.out.println(result.getInt(2));

Get length

JsonArray jsonArray = new JsonArray("[\"Hello\", \"World\", 17]");
System.out.println(jsonArray.length);

For loop

String rawData = "[\"Hello\", \"World\", 17]";
JsonArray result = new JsonArray(rawData);
for (Object i : result) {
    System.out.println(i);
}
