MyEclipse 7.5注册码

    MyEclipse是收费的，在开源软件大行其道的今天，总让人感到多少有些不便，我这些天也是一直在用MyEclipse 7.5，是三十天试用的，今天到期了，所以想办法找到注册码。
    很简单，新建一个工程，然后导入下面的java文件：
    MyecliseGen.java

 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) { 
     } 
  } 
  }
运行此文件，在控制台出现：
please input register name: 
随便一个名字，然后回车，即可出现注册码，然后在MyEclipse下，在菜单中选择 Myeclipse->Subscription Information 然后 输入Subscriber和Subscription code即可。
