java实现批量生成文件夹和批量修改文件名

1、上代码：

package com.yanhui.util;

import java.io.File;
import java.util.HashMap;
import java.util.Iterator;
import java.util.Map;
import java.util.Map.Entry;

@SuppressWarnings("rawtypes")
public class _fileUtil {
private Map map;
public _fileUtil(){
this.map=new HashMap();
    }
public Map getMap() {
return map;
    }

@SuppressWarnings("unchecked")
public _fileUtil addRegulation(String oldStr, String newStr){
this.map.put(oldStr, newStr);
return this;
    }

public static void multiFloder(String path, String[] files, String suffixName){
        String filename = "";
for(int i = 0; i<files.length;i++){
            filename = (i+1)+"-"+files[i];
            File f = new File(path+"\\"+filename+suffixName);
            f.mkdirs();
            System.out.println("创建文件夹成功！");
        }
    }

public static void multiRename(String path,_fileUtil replacementChain){
        File file = new File(path);
boolean isDirectory = file.isDirectory();
if(!isDirectory){
            System.out.println(path+"不是一个文件夹！");
return;
        }
        String[] files = file.list();
        File f = null;
        String filename = "";
        String oldFileName = "";

for(int i = 0; i<files.length;i++){
            oldFileName = files[i];
            filename = files[i];
            Map map = replacementChain.getMap();
            Iterator it = map.entrySet().iterator();
while(it.hasNext()){
                Map.Entry entry = (Entry) it.next();
                filename = filename.replace((String)entry.getKey(), (String)entry.getValue());
            }
            filename = (i+1)+"-"+filename;
            f = new File(path+"\\"+oldFileName);
            f.renameTo(new File(path+"\\"+filename));
            System.out.println("批量修改"+filename+"成功！");
        }
    }
}

2、生成指定的文件夹

String path = "F:\\test";
String[] files = {"a","b","c"};
String suffixName = "(艳辉网)";
        _fileUtil.multiFloder(path, files , suffixName );

4、批量改文件的名称
原图：

修改后：

代码实现：

_fileUtil replacementChain = new _fileUtil();
        replacementChain.addRegulation(".mp4", "(艳辉网分享福利的网站).mp4");
        _fileUtil.multiRename(false,"F:\\test\\1-a(艳辉网)", replacementChain);
