How to delete a temporary folder created in Java?

In Java, you can use the following method to delete a temporary folder:

import java.io.File;

public class DeleteTemporaryFolder {
    public static void main(String[] args) {
        // 创建临时文件夹
        File tempFolder = new File("path/to/temp/folder");

        // 删除临时文件夹
        deleteFolder(tempFolder);
    }

    public static void deleteFolder(File folder) {
        if (folder.exists()) {
            File[] files = folder.listFiles();
            if (files != null) {
                for (File file : files) {
                    if (file.isDirectory()) {
                        // 递归删除子文件夹
                        deleteFolder(file);
                    } else {
                        // 删除文件
                        file.delete();
                    }
                }
            }
            // 删除文件夹
            folder.delete();
        }
    }
}

The code will recursively delete all files and folders in the temporary folder and its subfolders, and finally delete the root folder itself. Please replace “path/to/temp/folder” in the code with the actual path to the temporary folder.
