馬上又要到情人節(jié)了，再不解風(fēng)情的人也得向女友表示表示。作為一個程序員，示愛的時候自然也要用我們自己的方式。
這里給大家上傳一段我在今年情人節(jié)的時候?qū)懡o女朋友的一段簡單的java swing代碼，主要定義了一個對話框，讓女友選擇是不是喜歡自己。如果她選了“是”，皆大歡喜，如果她想選“不”，哼哼。。。看一下截圖吧。
代碼效果圖：
接下來不廢話，直接上代碼了。新版本已上傳，也歡迎大家到我的github上下載和改進代碼（點此轉(zhuǎn)到github）。
另外就是因為這個代碼當(dāng)時是在情人節(jié)的時候?qū)懙?，對話框?biāo)題欄的信息也是與情人節(jié)相關(guān)，要想在其他的節(jié)日使用，只需要修改幾個字符串就可以了，我在需要修改的地方都打了中文注釋，大家可以很容易地找到。不過正如我在注釋里寫的那樣，這個程序頂多是你倆之間一個溫馨的小玩笑，你要是想今晚嘿嘿嘿的話，真正的禮物還是得備好哦: )
