利用Java实现指定文件夹下的照片以自定义格式移动

 1 public class FileRename {
 2     public static void main(String[] args) throws Exception {
 3         Integer n = Integer.valueOf(args[0]);
 4         String src = args[1];
 5         String dest = args[2];
 6         for (int i = 1; i <= n; i++){
 7             String name2 =" ("+i+")"+".png";
 8             String newName = src +name2;
 9             System.out.println("success:"+newName);
10             File afile=new File(newName);
11             FileInputStream fis = new FileInputStream(afile);
12             FileOutputStream fos = new FileOutputStream(new File(dest+i+".png"));
13             byte[] read = new byte[1024];
14             int len = 0;
15             while((len = fis.read(read))!= -1){
16                 fos.write(read,0,len);
17             }
18             fis.close();
