JSON 迭代
迭代 JSONObject
属性
JSONObject obj = new JSONObject("{\"isMarried\":\"true\", \"name\":\"Nikita\", \"age\":\"30\"}");
Iterator<String> keys = obj.keys();//all keys: isMarried, name & age
while (keys.hasNext()) { //as long as there is another key
String key = keys.next(); //get next key
Object value = obj.get(key); //get next value by key
System.out.println(key + " : " + value);//print key : value
}
迭代 JSONArray
值
JSONArray arr = new JSONArray(); //Initialize an empty array
//push (append) some values in:
arr.put("Stack");
arr.put("Over");
arr.put("Flow");
for (int i = 0; i < arr.length(); i++) {//iterate over all values
Object value = arr.get(i); //get value
System.out.println(value); //print each value
}
