IO流的复制

 1 public static void main(String[] args) throws Exception {
 2         // 1：输入流
 3         FileInputStream fis = new FileInputStream("1.png");
 4         // 2：输出流
 5         FileOutputStream fos = new FileOutputStream("1copy.png");
 6         // 实现复制
 7         byte[] buf = new byte[1024];
 8         int count=0;
 9         while ((count=fis.read(buf)) != -1){
10             System.out.println(count);
11             fos.write(buf,0,count);
12         }
13 
14         // 关闭流
15         fis.close();
16         fos.close();
17         System.out.println("处理完毕");
18 
19     }
