Java -如何在Java中删除文件夹中的文件？

import java.io.File;

public class DeleteFiles {
    public static void main(String[] args) {
        String folderPath = "path/to/folder";
        deleteFilesInFolder(folderPath);
    }

    public static void deleteFilesInFolder(String folderPath) {
        File folder = new File(folderPath);
        if (folder.exists()) {
            File[] files = folder.listFiles();
            if (files != null) {
                for (File file : files) {
                    if (file.isDirectory()) {
                        deleteFilesInFolder(file.getAbsolutePath());
                    } else {
                        file.delete();
                    }
                }
            }
            folder.delete();
        }
    }
}
