情人节写给女朋友Java Swing代码程序

马上又要到情人节了，再不解风情的人也得向女友表示表示。作为一个程序员，示爱的时候自然也要用我们自己的方式。

这里给大家上传一段我在今年情人节的时候写给女朋友的一段简单的Java Swing代码，主要定义了一个对话框，让女友选择是不是喜欢自己。如果她选了“是”，皆大欢喜，如果她想选“不”，哼哼。。。看一下截图吧。

代码效果图：

接下来不废话，直接上代码了。新版本已上传，也欢迎大家到我的github上下载和改进代码（点此转到github）。

另外就是因为这个代码当时是在情人节的时候写的，对话框标题栏的信息也是与情人节相关，要想在其他的节日使用，只需要修改几个字符串就可以了，我在需要修改的地方都打了中文注释，大家可以很容易地找到。不过正如我在注释里写的那样，这个程序顶多是你俩之间一个温馨的小玩笑，你要是想今晚嘿嘿嘿的话，真正的礼物还是得备好哦: )

/** 
 * 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.
