First, * the 'NO' button would change its position, it lookes like it attemps to escape * from being clicked. After a couple of rounds, if she/he still want to click * 'NO' button, the 'NO' button and 'YES' button will exchange their position. * Besides, the window will cannot be closed untill the 'YES' button is clicked. * * To use this code, please make sure her/his computer has installed the JRE. * * Note that this code is just a little joke, DO NOT USE IT AS A REAL VALENTIN'S * DAY GIFT, if you want to get laid at Valentin's Day, use ROSE, WINE and FANCY * RESTAURANT, if you want to keep your mate's love, use YOUR HEART. * * @author rainman_zjd * @version initialt version, 2016.3.20 */
