Java中创建Json对象的方法和详细代码

// 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?
/*
//代码效果参考：http://www.zidongmutanji.com/bxxx/165784.html

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"} 

]};
