将字符串的JSON数组转换为Java？

Question

I am trying to convert a JSON String array to Java which is given from this piece of javascript:

javaFunction(["a1", "a2"]); <--- This is called in javascript

In Java

public static void javaFunction(<What here?> jsonStringArray){  //<---- This is called in Java
    //Convert the JSON String array here to something i can iterate through,
    //For example:

    for(int index = 0; index < convertedArray.length; index++){
        System.out.println(convertedArray[index];
    }
}

Answer 1

You can use this :

List<String> list = new ArrayList<String>();
for(int i = 0; i < jsonStringArray.length(); i++){
  list.add(jsonStringArray.getJSONObject(i).getString("name"));
  }

Answer 2

I solved it using this:

In the JavaScript:

javaFunction(JSON.Stringify(["a1", "a2"]));

In Java

public static void javaFunction(String jsonArrayString){
   JSONArray jsonArray = new JSONArray(jsonArrayString);
   List<String> list = new ArrayList<String>();
   for(int i = 0; i < jsonArray.length(); i++){
      list.add(jsonArray.getString(i));
   }
}

Answer 3

Trim first and last bracket;

ie jsonArrayString = jsonArrayString.subStr(1,jsonArrayString.length()-1);

you will get "a1","a2","a3","a4"

Then use String's split function.

String[] convertedArray= jsonArrayString.split(",");
