java解析json数组字符串

在Java中解析JSON数组字符串可以使用Java自带的org.json库或者第三方库如Jackson、Gson等。

使用org.json库解析JSON数组字符串的示例代码：

import org.json.*;

String jsonArrayString = "[\"apple\", \"banana\", \"orange\"]";

JSONArray jsonArray = new JSONArray(jsonArrayString);

String firstFruit = jsonArray.getString(0);
String secondFruit = jsonArray.getString(1);
String thirdFruit = jsonArray.getString(2);

使用Jackson库解析JSON数组字符串的示例代码：

import com.fasterxml.jackson.databind.ObjectMapper;

String jsonArrayString = "[\"apple\", \"banana\", \"orange\"]";

ObjectMapper objectMapper = new ObjectMapper();

List<String> jsonList = objectMapper.readValue(jsonArrayString, new TypeReference<List<String>>(){});

String firstFruit = jsonList.get(0);
String secondFruit = jsonList.get(1);
String thirdFruit = jsonList.get(2);

使用Gson库解析JSON数组字符串的示例代码：

import com.google.gson.*;

String jsonArrayString = "[\"apple\", \"banana\", \"orange\"]";

Gson gson = new Gson();

List<String> jsonList = gson.fromJson(jsonArrayString, new TypeToken<List<String>>(){}.getType());

String firstFruit = jsonList.get(0);
String secondFruit = jsonList.get(1);
String thirdFruit = jsonList.get(2);
