将带有数组的对象列表与json文件相互转换

const objList = [
  { name: "Alice", age: 25 },
  { name: "Bob", age: 30 },
  { name: "Charlie", age: 35 }
];

const json = JSON.stringify(objList);
console.log(json);

const json = '[{"name":"Alice","age":25},{"name":"Bob","age":30},{"name":"Charlie","age":35}]';

const objList = JSON.parse(json);
console.log(objList);

import json

objList = [
  { "name": "Alice", "age": 25 },
  { "name": "Bob", "age": 30 },
  { "name": "Charlie", "age": 35 }
]

jsonStr = json.dumps(objList)
print(jsonStr)

import json

jsonStr = '[{"name":"Alice","age":25},{"name":"Bob","age":30},{"name":"Charlie","age":35}]'

objList = json.loads(jsonStr)
print(objList)

import com.google.gson.Gson;

Gson gson = new Gson();

System.out.println(jsonStr);
