J2SE批量生成J2ME的Jad小工具

本文主要是介绍J2SE批量生成J2ME的Jad小工具，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

     由于处理大量的jar包后，原来的jad就不能再用了，网上找了个JadGen.exe，也很好用，但是没有批量的功能。于是就自己写了个批量生成工具。

 

    实现功能：

    1.选择指定jar时，生成jad。

    2.选择指定存放jar的文件夹，可批量生成该文件夹下的jar的jad文件。

    3.支持生成在线安装jad。

 

    另外，自己发现用exe4j打包生成的exe可以不启动程序，直接将jar或文件夹拖动到程序图标上就可生成jad(但有exe4j的一个宣传splash或Dialog)。但用jsmooth生成的exe却没有这个功能，相当疑惑。

 

    代码如下：

 

package lab.sodino.jadgen; public class JadGenMain { public static void main(String[] args) { if (args == null || args.length == 0) { JadFrame frame = new JadFrame(); frame.setVisible(true); } else { JadGener.generateJad(args, null, true); } } }
