Introduction 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 <= 0) { System.err.println("当前路径文件不存在!"); return; } for (File f : files) { if (f.isDirectory()) { renameFiles(f.getPath(), oldExt, newExt); } else { String name = f.getName(); if (name.endsWith("." + oldExt)) { name = name.substring(0, name.lastIndexOf(".") + 1); name += newExt; f.renameTo(new File(f.getParent() + "\\" + name)); } } } } public static void main(String[] args) { Scanner sc = new Scanner(System.in); System.out.println("请输入要修改文件后缀名的文件夹:"); String path = sc.nextLine(); System.out.println("请输入修改前的后缀名:"); String oldExt = sc.nextLine(); System.out.println("请输入修改后的后缀名:"); String newExt = sc.nextLine(); renameFiles(path, oldExt, newExt); System.out.println("操作完成"); } }
其他方法
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。

Java 8 introduces the Stream API, providing a powerful and expressive way to process data collections. However, a common question when using Stream is: How to break or return from a forEach operation? Traditional loops allow for early interruption or return, but Stream's forEach method does not directly support this method. This article will explain the reasons and explore alternative methods for implementing premature termination in Stream processing systems. Further reading: Java Stream API improvements Understand Stream forEach The forEach method is a terminal operation that performs one operation on each element in the Stream. Its design intention is

Capsules are three-dimensional geometric figures, composed of a cylinder and a hemisphere at both ends. The volume of the capsule can be calculated by adding the volume of the cylinder and the volume of the hemisphere at both ends. This tutorial will discuss how to calculate the volume of a given capsule in Java using different methods. Capsule volume formula The formula for capsule volume is as follows: Capsule volume = Cylindrical volume Volume Two hemisphere volume in, r: The radius of the hemisphere. h: The height of the cylinder (excluding the hemisphere). Example 1 enter Radius = 5 units Height = 10 units Output Volume = 1570.8 cubic units explain Calculate volume using formula: Volume = π × r2 × h (4
