使用字节流复制文件

 1 public static void main(String[] args) throws IOException {
 2         FileInputStream fis = new FileInputStream("c:\\1.jpg");
 3         FileOutputStream fos = new FileOutputStream("d:\\1.jpg");
 4         int len = 0;
 5         byte[] bytes = new byte[1024];
 6         while ((len = fis.read(bytes)) != -1) {
 7             fos.write(Arrays.copyOf(bytes,len));
 8         }
 9         fos.close();
10         fis.close();
11     }
