Java遍历JsonObject对象

方法：

Iterator iter = jsonInfo.entrySet().iterator();

代码示例：

public class Test {
    public static void main(String[] args) {
        
        JSONObject jsonInfo = new JSONObject();

        String key1 = "a";
        jsonInfo.put(key1, "aa");
        String key2 = "b";
        jsonInfo.put(key2, "bb");
        
        Iterator iter = jsonInfo.entrySet().iterator();
        while (iter.hasNext()) {
            Map.Entry entry = (Map.Entry) iter.next();
            System.out.println(entry.getKey().toString());
            System.out.println(entry.getValue().toString());
        }
    }
}
