使用java[closed]将两个数组转换为json字符串对象

Question

我有两个数组,

id = [1,2,3]
pass = [a,b,c]

我如何将它转换成下面的json结构，在这里它应该以'['开始，以']'结束，

  [
    { 
       "user": "1", 
       "password": "a"
    },
   { 
       "user": "1", 
       "password": "a"
    },
   { 
       "user": "1", 
       "password": "a"
    }
   ]

Answer 1

JSONArray arr = new JSONArray();
JSONObject obj;
for( int i = 0; i < yourUserArr.length; i++ ){
  obj = new JSONObject();
  obj.put("user", yourUserArr[i]);
  obj.put("password", yourPassArr[i]);
  arr.put( obj );
}

然后将jsonarray转换成字符串

String data = arr.toString();
