基于Java編寫一個神奇的代碼恢復工具
更新時間：2024年04月03日 11:15:43 作者：愛碼少年
這篇文章主要為大家詳細介紹了如何基于Java編寫一個神奇的代碼恢復工具,文中的示例代碼簡潔易懂,感興趣的小伙伴可以跟隨小編一起學習一下
一、概述
小C是一名程序猿，他有好多新奇的點子，也樂于把這些變成文字分享給大家。這些分享大部分都與代碼相關，在文章里面把這些代碼全部按本來的結(jié)構(gòu)展示出來也不是一件容易的事！
二、工具展示
這不，最近開發(fā)了一個小工具，界面介紹如下:
三、工具下載地址
procode-simple-0.0.1.jar 提取碼: ca8z
四、運行過程
在輸入框里面輸入待恢復的代碼，點擊"開始恢復代碼" 便生成原始項目結(jié)構(gòu)的代碼。
大家可以下載jar，拷貝附件代碼嘗試運行！
五、附件待恢復代碼
代碼恢復數(shù)據(jù)框輸入的內(nèi)容為：
