生成MyEclipse6.5注册码的代码

/*
 以下是生成MyEclipse注册码的代码
 使用方法:
  将admin改成你的用户名,将-1912310改成生成注册码的到期时间
  到期时间距生成注册码的日期不能超过三年,否则生成的注册码无效
 代码使用方法:
 点File——New——Project...——随便输入一个工程名(如：MECrack)——Finish
 在左边目录树展开MECrack，右击Src——New——Class，在Name处输入类名，要和代码中的类名相同，这里代码中是MyEclipseCrack
 在代码编码按C+A全选并删除，再粘贴下面的代码
 在代码区右击——Run As——Java Application——OK，然后就可以在下面看到生成的激活码
