又是一年一度的情人节。
有文采的写文章发段子
有颜值的发自拍秀合照
有钱的发红包送礼物，
作为理工男呢，给喜欢的女生写一段代码也是不错的选择嘛！
废话不多说，直接上代码

/**
* A funny code for your lover, which creates a frame that let her/him choose
* whether she/he loves you. If she/he choose 'YES', everythingis normal, but
* if she/he tries to choose 'NO', something interestingwould happen. 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.
