我已经签署了一个免费的谷歌地图api帐户来提取基于一个地方的名称的经度和纬度。现在，我设法获得了地点的坐标。不过，在Java中，有没有办法根据我从下面的程序中获得的经度和纬度来提取位置的城市名称？如何获得坐标为IN JAVA的城市名称？

while ((output = br.readLine()) != null) {
//System.out.println(output);
out+=output;
}
// Converting Json formatted string into JSON object
JsonParser parser = new JsonParser();
JsonObject json = (JsonObject) parser.parse(out);
JsonArray results = json.getAsJsonArray("results");
//codes for getting sublocality...
System.out.println(results);
conn.disconnect();

这里是从的System.out.println输出（结果）：

如果我只是想提取城市名，即sublocality，我应该如何修改代码？
什么是44行？ –
