参考技术A 留下邮箱吧追问

这是我们选修课的课程设计，我们一共才上七次课。老师要求做成 【.exe】格式直接安装。就能在Java build 上运行，还要有系统分析。求大哥帮帮忙啊！如能帮我解决感激不尽啊 ！请密我QQ 394401721

请问大家，能不能修改jar包中已有的文件呢？

如题，谢谢。
额。在程序中，，，通过程序，不是通过解压再重新打包。。。

可以。修改完后，自己重新打包（用7z，可以只更新包中某个文件），或放在classes中。追问

额。在程序中，，，通过代码，不是通过解压再重新打包。。。

参考技术A 能，先解压，打开然后修改，保存，再压缩就可以了 参考技术B JAVA是可以操作压缩文件的，可以通过程序去改压缩文件中的内容，具体实现，你可以去查找相关的API

可以先解压文件，修改完了，再重新压缩 参考技术C 这个必须能啊。。。 参考技术D 使用classloader
