Java中创建Json对象

// 声明两个json数组  
[java] view plain copy print?
      JSONArray gResTable = new JSONArray();   
      JSONArray gCmtTable = new JSONArray();   
// 声明json对象       
ONObject outData = new JSONObject();  
//把json数组加到json对象中  
[java] view plain copy print?
outData.put("ResTable", gResTable);  
outData.put("CmtTable", gCmtTable);  
  //此时创建出来的如下:jsonData={"ResTable":[],"CmtTable":[]};  
  把json数据加到json数组中  
for (int i = 0; i < 2; i ++)  
{  
    JSONObject node = new JSONObject();  
    node.put("thumb_path", "./Image/" + i +".gif");  
    node.put("flash_path", "./Image/" + i +".gif");  
    node.put("desc1", "可疑车辆" + i);  
    node.put("desc2", "");  
    node.put("desc3", "");  
    node.put("desc4", "");  
    node.put("title", "hello");  
    node.put("upload_time", (new java.util.Date()).toString());  
    node.put("uploader", "王二");  
    gResTable.put(node);  
}  

for (int i = 0; i < 2; i ++)  
{  
    JSONObject node = new JSONObject();  
    node.put("logo_path", "./Image/" + i +".gif");  
    node.put("comment", "hello");  
    node.put("comment_time", (new java.util.Date()).toString());  
    node.put("author", "王二");  
    gCmtTable.put(node);  
}  
建出来的json格式如下：  
[java] view plain copy print?
/* 
    jsonData={"ResTable":[ 
    {"upload_time":"Sat May 26 20:16:37 CST 2012","title":"hello","flash_path":"./Image/0.gif","uploader":"王二","thumb_path":"./Image/0.gif","desc3":"","desc4":"","desc1":"可疑车辆0","desc2":""}, 
    {"upload_time":"Sat May 26 20:16:37 CST 2012","title":"hello","flash_path":"./Image/1.gif","uploader":"王二","thumb_path":"./Image/1.gif","desc3":"","desc4":"","desc1":"可疑车辆1","desc2":""}], 
    "CmtTable": 
    [{"author":"王二","logo_path":"./Image/0.gif","comment":"hello","comment_time":"Sat May 26 20:16:37 CST 2012"}, 
    {"author":"王二","logo_path":"./Image/1.gif","comment":"hello","comment_time":"Sat May 26 20:16:37 CST 2012"} 
 ]}; 
*/
