json字符串转换为JSONObject和JSONArray

一.下载json 具体到/上找java-json下载，并把其放到项目源代码中，这样就可以引用其类对象了

二.具体转化过程

//JSONObject

 String jsonMessage = "{\"语文\":\"88\",\"数学\":\"78\",\"计算机\":\"99\"}";
  String value1 = null;
  try
  {
   //将字符串转换成jsonObject对象
   JSONObject myJsonObject = new JSONObject(jsonMessage);
   //获取对应的值
   value1 = ("数学");
  }
  catch (JSONException e)
  {
  }
  
  ("value1="+value1);

//JSONArray

jsonMessage = "[{'num':'成绩', '外语':88, '历史':65, '地理':99, 'object':{'aaa':'1111','bbb':'2222','cccc':'3333'}}," +
           "{'num':'兴趣', '外语':28, '历史':45, '地理':19, 'object':{'aaa':'11a11','bbb':'2222','cccc':'3333'}}," +
           "{'num':'爱好', '外语':48, '历史':62, '地理':39, 'object':{'aaa':'11c11','bbb':'2222','cccc':'3333'}}]";
  JSONArray myJsonArray;
  try
  {
   myJsonArray = new JSONArray(jsonMessage);
   
   for(int i=0 ; i < () ;i++)
   {
    //获取每一个JsonObject对象
    JSONObject myjObject = (i);
    
    //获取每一个对象中的值
    String numString = ("num");
    int englishScore = ("外语");
    int historyScore = ("历史");
    int geographyScore = ("地理");
    //获取数组中对象的对象
    JSONObject myjObject2 = ("object");
    String aaaString = ("aaa");
    ("aaaString="+aaaString);
    
    ("numString="+numString);
    ("englishScore="+englishScore);
    ("historyScore="+historyScore);
    ("geographyScore="+geographyScore);
   }
  }
  catch (JSONException e)
  {
  }
