Java读写json

    
    

public static void create(){


   //创建JSON对象


   //①直接构造JSON对象


   JSONObject json = new JSONObject();


   try {


      JSONArray jsonMembers = new JSONArray();  //创建json数组


      JSONObject member1 = new JSONObject();   //创建空json对象


      ("name","Assad");           //向json对象中放置键值对


      ("home","Guangzhou");






      JSONObject member2 = new JSONObject();


      ("name","John");


      ("home","Shanghai");






      (member1);


      (member2);


      ("persons",jsonMembers);


   }catch(JSONException ex){


      ();


   }


   //②直接将Java对象转化为JSON对象


   Perosns persons= new Persons();


   JSONObject json = (persons);*/






   //写入文件：将JSON对象转化为字符串后写入文件


   String jsonStr = ();   //将JSON对象转化为字符串


   try{


      PrintWriter writer = new PrintWriter(new BufferedWriter(new FileWriter(new File("test_create.json"))));


      (jsonStr);


      ();


    }catch(IOException ex){


       ();


    }
