As you can image,if I gonna learn the courses course-to-course.I gonna find it difficult and boring to find each them,and the sort type is not what we want. So I have to rename the file as simple as possible.

Here is just  a segment code that demonstates how to use the  File.renameTo(File).

 1 public static void main(String[] args) {

 2         String path = "H:\\Java\\JavaSE\\";

 3         File root = new File(path);

 4         String oriName = "";

 5         String newName = "";

 6         String toClip = "[北京圣思园Java培训教学视频]Java.SE.";

 7         for (String f : root.list()) {

 8             File fSub = new File(path + f); //File to be rename(Must append from the root path).

 9             if (!fSub.isFile())    //Only operate File.

10                 continue;

11             if (fSub.getName().startsWith(toClip)) {

12                 oriName =fSub.getName();

13                 newName = oriName.substring(toClip.length());

14                 File fSubNew = new File(path + newName);    //The target File.

15                 if(fSub.renameTo(fSubNew))

16                     System.out.println(fSub.getAbsolutePath() + " rename successfully");

17                 else 

18                     System.out.println(fSub.getAbsolutePath() + " rename failed");

19             }

20         }

21     }
