 2         
 3         FileInputStream fi=new FileInputStream("e:/retire.png");  
 4         BufferedInputStream in=new BufferedInputStream(fi); 
 5         FileOutputStream fo=new FileOutputStream("d:/ss.png"); 
 6         BufferedOutputStream out=new BufferedOutputStream(fo); 
 7         byte[] buf=new byte[1024];  
 8         int len=in.read(buf);//读文件，将读到的内容放入到buf数组中，返回的是读到的长度  
 9         
10         while(len!=-1){
11             out.write(buf, 0, len);
12             len=in.read(buf);
13         } 
14         out.close();  
15         fo.close();  
16         in.close();  
17         fi.close();
