这个是我自己写的代码，编译没有错误，也能运行，但是复制的文件少了数据，不知道什么原因，求大神们给看看哪里有错误

还有，为什么上面的代码都没有层次了，以前发帖还是有层次的？

正解，将 PrintWriter 改为 PrintStream
out.println(new String(buf,0,len)); 换为 out.write( buf, 0, le ...

恩，是的，我把这个忘记了，谢谢提醒:handshake

正解，将 PrintWriter 改为 PrintStream
out.println(new String(buf,0,len)); 换为 out.write( buf, 0, len ) ; 就行了。
