Question

下边的代码怎么用java8的新特性写 感激不尽。。。

if (jsonArray.size()>0){
for(int i = 0;i< jsonArray.size();i++){
JSONObject jb = jsonArray.getJSONObject(i);
User user = new User();
user.setName(jb.getString("name"));
user.setAge(jb.getInt("age"));
userDao.saveUser(user);
}
}

Answer 1

JSONArray array = JSONArray.fromObject("[{'name':'hehe','age':22}]");
List<Customer> list = JSONArray.toList(array, Customer.class);
list.stream().forEach(jb -> {
User user = new User();
user.setName(jb.getString("name"));
user.setAge(jb.getInt("age"));
userDao.saveUser(user);
});
