JSONBuilder的用法

JSONBuilder可以向文件中寫入寫入json字符串。如下面的例子：

public class Test
{
    public static void main(String args[]) throws IOException
    {
        File f = new File("d:" + File.separator + "test.txt");
        FileWriter fw = new FileWriter(f);
        JSONBuilder builder = new JSONBuilder(fw);
        builder.object();
        builder.key("Json");
        builder.value("Hello, World!");
        builder.endObject();
        fw.flush();
        fw.close();
    }
}
