将多个json字符串转换为一个字符串

var jsonStrings = [
  '{"name":"John","age":30,"city":"New York"}',
  '{"name":"Jane","age":25,"city":"San Francisco"}',
  '{"name":"Bob","age":35,"city":"Seattle"}'
];

var combinedString = JSON.stringify(jsonStrings);
console.log(combinedString);

["{\"name\":\"John\",\"age\":30,\"city\":\"New York\"}","{\"name\":\"Jane\",\"age\":25,\"city\":\"San Francisco\"}","{\"name\":\"Bob\",\"age\":35,\"city\":\"Seattle\"}"]

import json

json_strings = [
    '{"name":"John","age":30,"city":"New York"}',
    '{"name":"Jane","age":25,"city":"San Francisco"}',
    '{"name":"Bob","age":35,"city":"Seattle"}'
]

combined_string = json.dumps(json_strings)
print(combined_string)

import com.google.gson.Gson;

public class Main {
    public static void main(String[] args) {
        String[] jsonStrings = {
            "{\"name\":\"John\",\"age\":30,\"city\":\"New York\"}",
            "{\"name\":\"Jane\",\"age\":25,\"city\":\"San Francisco\"}",
            "{\"name\":\"Bob\",\"age\":35,\"city\":\"Seattle\"}"
        };

        Gson gson = new Gson();
        String combinedString = gson.toJson(jsonStrings);
        System.out.println(combinedString);
    }
}
