myeclipse6.5-8.5_注册码_注册机_激活码生成代码

//使用方法：新建一个.java文件，然后新建一个MyEclipseGen类，复制下面代码，运行程序。生成激活码import java.io.BufferedReader;   import java.io.IOException;   import java.io.InputStreamReader;     public class MyEclipseGen {   private static final String LL = "Decompiling this copyrighted software is a violation of both your license agreement and the Digital Millenium Copyright Act of 1998 (http://www.loc.gov/copyright/legislation/dmca.pdf).
