贴一个老子竹的小程序

批量更改目录及子目录下文件名.

package filename;

import java.io.File;

public class BathChgName {

	private int i=1;
	public static void main(String[] args) {
		new BathChgName().chgname("D:/陈冠希/新建文件夹/张柏芝","张柏芝");

	}
	public void chgname(String dirPath,String bname){
		File file=new File(dirPath);
		File[] list=file.listFiles();

		for(File f:list){
			if(f.isDirectory()){
				chgname(f.getPath(),bname);
			}else{
			String name=f.getParent()+"/"+bname+"_"+i+".jpg";
			f.renameTo(new File(name));
			}
			i++;
		}
	}

}
