在初始化链表时:

last = first; /* Biblical reference */

简洁而滑稽。

这是显而易见的?

/** Logger */
private Logger logger = Logger.getLogger();

 // WARNING!!!
 // Very perversive code ahead!

... about a 20 lines of "very perversive" code ...

// Now you can call your grandmother back. ;)

生产源代码:

// Remove this if you wanna be fired

// If this comment is removed the program will blow up 

// fix for groupid > 9 
// if groupid ever gets to 100 everything will break (again)

if (groupid < 10) {
groupid = "0" + groupid;
}
