myeclipse注册码？激活码？Subscription Code

打开你的myeclipse，新建一个java项目。

在新建的项目下创建一个类，具体如下步骤。

在该类下，加入下列打码（将下列代码复制到code类中）package demo;import java.io.BufferedReader;  import java.io.IOException;  import java.io.InputStreamReader; public class code { 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 code() {     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();     code myeclipsegen = new code();      String res = myeclipsegen.getSerial(userId, '5');      System.out.println('Serial:' + res);      reader.readLine();     } catch (IOException ex) {     }   }   }

然后运行该类。具体如下

运行后控制，输入登录账户然后回城就能生产注册码。

在myeclipse栏目下找到subscription information选项

将生成的注册码复制到对应位置，完成激活（一定时间内）。
