主要是实现两个功能：
1.顺序输出：
用户通过使用方法setP来插入数据，三个参数分别为key，value，和comment。之后通过orderStore来输出内容。
2.为每条属性添加注释
通过setP方法添加的属性都会有注释参数。如果只想使用注释这个功能，可以通过java的Properties类来构造此类对象，之后通过addComment方法来为想要添加的属性添加注释
测试程序：
[java]
public static void main(String[] args) throws IOException
{
OutputOrderProperties properties = new OutputOrderProperties();
FileOutputStream fileOutputStream = new FileOutputStream("test.properties");
OutputStreamWriter writer = new OutputStreamWriter(fileOutputStream);
for(int i=0 ; i<10; i++)
{
String string = String.valueOf(i);
properties.setP("Name"+string, string, "the name of "+string);
}
properties.orderStore(writer, "This is a test process...");
}
结果：
