robber斑竹，帮我解决一下这个问题好吗？

能否给一个可以解“quoted-printable”格式的Java程序？

你的mail server支持双字节吗？
是否是他的问题？

因该支持！Mail Server是Imail，因该是解码的问题。
我用下面的C代码可以解码，但是转化成Java代码有问题！
你能帮我转化一下吗？
#include <stdio.h>
void main(int argc, char * argv[])
{
FILE * fp; char ch, ch1, ch2;  char hz;
fp = fopen("data.txt", "rt");
for (;;)
{
   ch = getc(fp); if (ch == EOF) break;
   if (ch == '=')
   {
      ch1 = getc(fp); if (ch1 == '\n') continue;
      ch2 = getc(fp);
      if (ch1>=65)
               ch1-=55;
             else ch1-=48;
             if (ch2>=65)
               ch2-=55;
             else ch2-=48;

             hz=(ch1<<4);
             hz|=ch2;
     putchar(hz);
    }
    else putchar(ch);
}
fclose(fp);
}

好像对Subject等等都可以，可是内容不行。

根据你的环境我在imail6.04+jdk1.3上调试成功！

to robber(海盗)　:
  谢谢你的热心帮助，但是还是不行，可能是你在测试的时候发的邮件使用Imai客户端发的，
如果你用Foxmail3.1发封邮件再收的话，则显示的是一些数字。因为Imail发送邮件时没有对
邮件体进行编码，而Foxmail则对其采用了”quoted-printable“格式的编码，上面你的程序
对其进行了解码，但是没有成功。上面那段C程序完全可以对“quoted-printable”进行解码，
我测试过，但是你的解码程序输出的是一些字母和数字，如下：
  这是第 1 封邮件

谢谢 robber(海盗) 我已经作出来啦！

谢谢你啦！不知道为什么CSDN总是给不了分，今天总于
可以给分了，所以拖的这么迟！希望以后能多多指教！
