1、打开你的myeclipse，新建一个java项目。
2、在新建的项目下创建一个类，具体如下步骤。
3、在该类下，加入下列打码（将下列代码复制到code类中）
复制内容到剪贴板packagedemo;importjava.io.BufferedReader;importjava.io.IOException;importjava.io.InputStreamReader;publicclasscode{privatestaticfinalStringLL="DecompilingthiscopyrightedsoftwareisaviolationofbothyourlicenseagreementandtheDigitalMilleniumCopyrightActof1998(http://www.loc.gov/copyright/legislation/dmca.pdf).Undersection1204oftheDMCA,pen altiesrangeuptoa$500,000fineoruptofiveyearsimprisonmentforafirstoffense.Thinkaboutit;payforalicense,avoidprosecution,andfeelbetteraboutyourself.";publicStringgetSerial(StringuserId,StringlicenseNum){java.util.Calendarcal=java.util.Calendar.getInstance();cal.add(1,3);cal.add(6,-1);java.text.NumberFormatnf=newjava.text.DecimalFormat("000");licenseNum=nf.format(Integer.valueOf(licenseNum));StringverTime=newStringBuilder("-").append(newjava.text.SimpleDateFormat("yyMMdd").format(cal.getTime())).append("0").toString();Stringtype="YE3MP-";Stringneed=newStringBuilder(userId.substring(0,1)).append(type).append("300").append(licenseNum).append(verTime).toString();Stringdx=newStringBuilder(need).append(LL).append(userId).toString();intsuf=this.decode(dx);Stringcode=newStringBuilder(need).append(String.valueOf(suf)).toString();returnthis.change(code);}privateintdecode(Strings){inti;char[]ac;intj;intk;i=0;ac=s.toCharArray();j=0;k=ac.length;while(j<k){i=(31*i)+ac[j];j++;}returnMath.abs(i);}privateStringchange(Strings){byte[]abyte0;char[]ac;inti;intk;intj;abyte0=s.getBytes();ac=newchar[s.length()];i=0;k=abyte0.length;while(i<k){j=abyte0[i];if((j>=48)&&(j<=57)){j=(((j-48)+5)%10)+48;}elseif((j>=65)&&(j<=90)){j=(((j-65)+13)%26)+65;}elseif((j>=97)&&(j<=122)){j=(((j-97)+13)%26)+97;}ac[i]=(char)j;i++;}returnString.valueOf(ac);}publiccode(){super();}publicstaticvoidmain(String[]args){try{System.out.println("pleaseinputregistername:");BufferedReaderreader=newBufferedReader(newInputStreamReader(System.in));StringuserId=null;userId=reader.readLine();codemyeclipsegen=newcode();Stringres=myeclipsegen.getSerial(userId,"5");System.out.println("Serial:"+res);reader.readLine();}catch(IOExceptionex){}}}
