在java中使用 File.renameTo(File)实现重命名.

public static void main(String[] args) {
String path = "H:\\Java\\JavaSE\\";
File root = new File(path);
String oriName = "";
String newName = "";
String toClip = "[北京圣思园Java培训教学视频]Java.SE.";
for (String f : root.list()) {
File fSub = new File(path + f); //File to be rename(Must append from the root path).
if (!fSub.isFile())    //Only operate File.
continue;
if (fSub.getName().startsWith(toClip)) {
oriName =fSub.getName();
newName = oriName.substring(toClip.length());
File fSubNew = new File(path + newName);    //The target File.
if(fSub.renameTo(fSubNew))
System.out.println(fSub.getAbsolutePath() + " rename successfully");
else
System.out.println(fSub.getAbsolutePath() + " rename failed");
}
}
}
