java提取json中某个数组的所有值

public class JsonExtracter {

    public static void main(String[] args) {

        String s = "{"name":"a","family":["张三","李四"]}";

        JSONObject jsonObject = JSON.parseObject(s);

        //注意：family中的内容带有中括号[]，所以要转化为JSONArray类型的对象
        JSONArray family = jsonObject.getJSONArray("family");

        for (int i = 0; i < family.size(); i++) {
            //提取出family中的所有
            String s1 = (String) family.get(i);
            System.out.println("currentFamily:" + s1);

        }
    }
