不使用myeclipse注册机得到myeclipse注册码的方法(myeclipse序列号)

代码如下:

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). Under section 1204 of the DMCA, penalties range up to a $500,000 fine or up to five years imprisonment for a first offense. Think about it; pay for a license, avoid prosecution, and feel better about yourself.";   
public String getSerial(String userId, String licenseNum) {   
   java.util.Calendar cal = java.util.Calendar.getInstance();   
   cal.add(1, 3);   
   cal.add(6, -1);   
   java.text.NumberFormat nf = new java.text.DecimalFormat("000");   
   licenseNum = nf.format(Integer.valueOf(licenseNum));   
   String verTime = new StringBuilder("-").append(new java.text.SimpleDateFormat("yyMMdd").format(cal.getTime())) .append("0").toString();   
   String type = "YE3MP-";   
   String need = new StringBuilder(userId.substring(0, 1)).append(type).append("300").append(licenseNum).append(verTime).toString();   
   String dx = new StringBuilder(need).append(LL).append(userId).toString();   
   int suf = this.decode(dx);   
   String code = new StringBuilder(need).append(String.valueOf(suf)).toString();   
   return this.change(code);   
}   
private int decode(String s) {   
   int i;   
   char[] ac;   
   int j;   
   int k;   
   i = 0;   
   ac = s.toCharArray();   
   j = 0;   
   k = ac.length;   
   while (j < k) {   
    i = (31 * i) + ac[j];   
    j++;   
   }   
   return Math.abs(i);   
}   
private String change(String s) {   
   byte[] abyte0;   
   char[] ac;   
   int i;   
   int k;   
   int j;   
   abyte0 = s.getBytes();   
   ac = new char[s.length()];   
   i = 0;   
   k = abyte0.length;   
   while (i < k) {   
    j = abyte0[i];   
    if ((j >= 48) && (j <= 57)) {   
     j = (((j - 48) + 5) % 10) + 48;   
    } else if ((j >= 65) && (j <= 90)) {   
     j = (((j - 65) + 13) % 26) + 65;   
    } else if ((j >= 97) && (j <= 122)) {   
     j = (((j - 97) + 13) % 26) + 97;   
    }   
    ac[i] = (char) j;   
    i++;   
   }   
   return String.valueOf(ac);   
}   
public MyEclipseGen() {   
   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();   
    MyEclipseGen myeclipsegen = new MyEclipseGen();   
    String res = myeclipsegen.getSerial(userId, "5");   
    System.out.println("Serial:" + res);   
    reader.readLine();   
   } catch (IOException ex) {   
   }   
}   
}

新建Java项目，复制该代码新建类MyEclipseGen，运行该代码，在控制台中会出现：

代码如下:

please input register name:

×××××（输入你的name,随便什么）

即生成序列号： ××××× ××××× ×××××...

进入myeclipse,在菜单中选择 Myeclipse->Subscription Information 然后 输入Subscriber和Subscription code即可。
