MyEclipse8.5破解方法
本文是转自其它博文，用以留着备份的~
Step：
1、建立一个任意名称的Java Project
2、在该工程中建立一个名文MyEclipseGen的Java文件(MyEclipseGen.java)
3、运行下面的代码，会在控制台出现" please input register name:"，输入任意一个名字，回车后生成序列号
4、点击 MyEclipse菜单中Window→Preferences→MyEclipse→Subscription，在右侧点击“Enter Subscription”
5、在弹出框中Subscriber中输入第3步的名字，在Subscription Code中输入第3步生成的序列号
Code：
import
java.io.BufferedReader;
import
java.io.IOException;
import
java.io.InputStreamReader;
