java - JSON 数组解析

Question

如何解析一个JSON数组，假设我们下面给出了一个数组，如何在Java中解析这个数组，请帮我写一段代码。

[{"guild": "Crimson", "region": "us", "realm": "Caelestrasz", "timestamp": 1311860040}, {"guild": "Crimson", "region": "us", "realm": "Caelestrasz", "timestamp": 1311511740}]

Answer 1

String gameJSON = "[{\"guild\": \"Crimson\", \"region\": \"us\", \"realm\": \"Caelestrasz\", \"timestamp\": 1311860040}, {\"guild\": \"Crimson\", \"region\": \"us\", \"realm\": \"Caelestrasz\", \"timestamp\": 1311511740}]";
JSONArray array = new JSONArray(gameJSON);
for (int i = 0; i < array.length(); i++) {
    System.out.println(array.getJSONObject(i));
}
// Access by key : value
for (int i = 0; i < array.length(); i++) {
    JSONObject element = array.getJSONObject(0);
    System.out.format("Player #%d: Realm = %s, Guild = %s\n"
                          , i + 1, element.get("realm"),element.get("guild"));

}
