Java JSONArray Get Values Guide

To retrieve values in Java using JSONArray, you can use its get method. The specific steps are as follows:

  1. First, use the parse method of JSONObject to parse the JSON string into a JSONArray object, for example:
String jsonString = "[\"value1\", \"value2\", \"value3\"]";
JSONArray jsonArray = new JSONArray(jsonString);
  1. Next, retrieve the value at a specified position using the get method, with positions starting at 0, for example:
String value1 = jsonArray.get(0).toString(); // 获取第一个值,结果为 "value1"
String value2 = jsonArray.get(1).toString(); // 获取第二个值,结果为 "value2"
String value3 = jsonArray.get(2).toString(); // 获取第三个值,结果为 "value3"

By using this method, you can extract and process values from a JSONArray one by one. It is important to note that when extracting values, you need to convert them to the corresponding data types based on the actual situation.
