MyEclipse7.0 M1下载和注册码

首先介绍下，这款MyEclipse7.0 M1已经内置了Eclipse3.4，所以无需再去下载。

1.下载地址：
http://downloads.myeclipseide.com/downloads/products/eworkbench/7.0M1/MyEclipse_7.0M1_E3.4.0_Installer.exe

2.编写如下代码,生成自己的MyEclipse7.0用户名和注册码

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
public class zhuce {
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).

Think about it; pay for a license, avoid prosecution, and feel better about yourself.";

public zhuce() {
super();
}
public static void main(String[] args) {
try { System.out.println("please input register name:");
BufferedReader reader = new BufferedReader(new InputStreamReader( System.in));
String userId = null;
userId = reader.readLine();
zhuce myeclipsegen = new zhuce();
String res = myeclipsegen.getSerial(userId, "5");
System.out.println("Serial:" + res);
reader.readLine();
}
catch (IOException ex) {
}
}
} 

运行 java工程的 zhuce.java类
