关于myeclipse5.1下载地址和注册码机的源代码

下载myeclipse5.1的话需要去myeclipse的官方网站,共有100多M之大, 点击这里进入下载 (进入官方网站后点download area,注册一个用户进行下载,如果你的确下不了，也可留言给我，我发给你。)，下在完成后接下来就是注册了。

如果你之前是用过myeclise3.2之类的话就无需再注册，新安装完成后就原来的注册仍然有效。如果你是新安装的话就需注册了， 你可以使用以前的myeclise3.2的注册机来注册，算法并没有改变，如果你要找3.x的注册机的话，用不着了。下面我贴出注册机的java源代码,直接运行此class就能生成注册码并可成功注册。

注册机源代码如下：
 

public class Main {
    private static final String L = "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 static void main(String[] args) {
        String userId = "xianyun";
         // MyEclipse4.1 GA
         // 其中491(4.9.1)/400(4.0)/401(4.1)/501(5.1.0)，()内为版本号，9912310代表注册码过期时间2099/12/31
         String need = userId.substring(0, 1) + "YE3MP-401-00-9912310";
         // MyEclipse4.0.0 GA
         // String need = userId.substring(0,1) + "YE3MP-400-01-9912310";
         // MyEclipse4.9.1
         // String need = userId.substring(0,1) + "YE3MP-491-01-9912310";
         // MyEclipse5.1.0 GA
         // String need = userId.substring(0,1) + "YE3MP-501-00-9912310";
         String dx = need + L + userId;
         int suf = decode(dx);
         // System.out.println("SUF:"+suf);
         String code = need + suf;
         System .out.println(change(code));
    }

    static int decode(String s) {
        int i = 0;
        char ac[] = s.toCharArray();
        int j = 0;
        for (int k = ac.length; j < k; j++) {
            i = 31 * i + ac[j];
        }
        return Math.abs(i);
        }

    static String change(String s) {
        byte abyte0[] = s.getBytes();
        char ac[] = new char[s.length()];
        int i = 0;
        for (int k = abyte0.length; i < k; i++) {
            int 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;
        }
        return String.valueOf(ac);
     }
}
