java 创建json对象

   // 声明两个json数组

         JSONArray gResTable = new JSONArray(); 
         JSONArray gCmtTable = new JSONArray(); 
   // 声明json对象		
	JSONObject outData = new JSONObject();
   //把json数组加到json对象中

	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);
	}
创建出来的json格式如下：

/*
    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"}
 ]};
