HomeJavajavaTutorialIntroduction to the method of batch modifying file suffixes in Java

本篇文章给大家带来的内容是关于java批量修改文件后缀的方法介绍,有一定的参考价值,有需要的朋友可以参考一下,希望对你有所帮助。

突然需要改一堆文件的后缀名,所以想编程解决,话不多说直接上代码

java

import java.io.File;
import java.util.Scanner;

public class FileEdit {

    public static void renameFiles(String path, String oldExt, String newExt) {
        File file = new File(path);
        if (!file.exists()) {
            System.err.println("文件路径不存在!");
            return;
        }
        File[] files = file.listFiles();
        if (files.length <p style="white-space: normal;">其他方法</p><p>在网上查了下,发现还有cmd命令可以解决,比如将txt后置改为7z,那么在你需要修改的目录运行cmd然后输入命令ren *.txt *.rar,就可以将所有txt结尾的文件进行修改;此外可以将本命令保存为bat脚本文件,双击进行运行。</p>本篇文章到这里就已经全部结束了,更多其他精彩内容可以关注PHP中文网的<a href="http://www.php.cn/course/list/36.html" target="_blank">Java教程视频</a>栏目!<p></p>
