1、使用for循环进行遍历，直接上代码吧：
/**
* 遍历JSONArray
*/
private static void LoopJSONArray(){
//颜色数组字符串
String colorStr = "[{'name':'刘德华','age':28,'sex':'男'}," +
"{'name':'张学友','age':29,'sex':'男'}]";
//转化为数组
JSONArray jsonArr = JSONArray.fromObject(colorStr);
for (int i = 0; i < jsonArr.size(); i++) {
JSONObject jsonObject = jsonArr.getJSONObject(i);
String name = jsonObject.getString("name");
Integer age = (Integer) jsonObject.get("age");
System.out.println("name:"+name+";age:"+age);
}
}
输出结果：
name:刘德华;age:28
name:张学友;age:29
2、使用Iterator进行遍历，也是直接上代码：
/**
* 遍历JSONArray
*/
private static void LoopJSONArray(){
//颜色数组字符串
String colorStr = "[{'name':'刘德华','age':28,'sex':'男'}," +
"{'name':'张学友','age':29,'sex':'男'}]";
//转化为数组
JSONArray jsonArr = JSONArray.fromObject(colorStr);
Iterator<Object> it = jsonArr.iterator();
List<JSONObject> list = new ArrayList<JSONObject>();
while (it.hasNext()) {
JSONObject jsonObj = (JSONObject) it.next();
String name = jsonObj.getString("name");
Integer age = (Integer) jsonObj.get("age");
System.out.println("name:"+name+";age:"+age);
}
}
输出结果：
name:刘德华;age:28
name:张学友;age:29
