文件重命名

最近有个需求，需要对文件夹下某一格式的文件进行全部重命名，用到了java的File类，代码实现相当简单，留着以后再用

package com;

import java.io.File;
import java.io.FilenameFilter;

public class Rename {
    private String fold=null;
    private File []files=null;
    private String fileType=null;
    
    public void findFile(String fold,final String type){
        this.setFold(fold);
        this.setFileType(type);
        File dir=new File(fold);
        files=dir.listFiles(new FilenameFilter() {
            
            @Override
            public boolean accept(File dir, String filename) {
                // TODO Auto-generated method stub
                return filename.endsWith("."+type);
            }
        });
    }
    public void renameFiles(String fold, String type){
        this.findFile(fold, type);
        int count=1;
        for (File file:this.files){
            file.renameTo(new File(fold + "\\"+ "1_"+count+"."+type));//命名格式为1_xx.wav
             count++;
        }
    }

    public String getFold() {
        return fold;
    }

    public void setFold(String fold) {
        this.fold = fold;
    }

    
    public String getFileType() {
        return fileType;
    }

    public void setFileType(String fileType) {
        this.fileType = fileType;
    }
    
    public static void main(String []args){
        String fold="E:\\data";
        String type="wav";
        
        Rename rn=new Rename();
        rn.renameFiles(fold, type);
    }

}
