就是利用MyEclipse自身写一个JAVA程序，然后再MyEclipse运行，最后你输个名字，结果就有

注册码了，太假了！ 大家自己试试，以后不用再上网上找注册码了，自己一个Run As就OK了 试试吧 步骤： 1、建立java Project，任意取个名字就行。 2、建立一个名字为MyEclipseGen的类文件，内容见下面附件。 3、运行该代码，在控制台中会出现：   please input register name:   (随便你怎么输)   即生成序列号： 4、进入myeclipse,输入Subscriber和Subscription code即可。 附件代码： 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).
