myeclipse 8.5 序列号

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;
