Path not existsPath existsCreateFolderCreateFile 总结 通过本文的介绍,我们了解了如何利用Java代码实现自动创建Java文件并同时创建文件夹的功能。这种方法可以帮助我们提高开发效率,省去手动创建文件夹的步骤。希望本文对于您理解这一功能有所帮助,谢谢阅读!
2.1. Files.createDirectory创建文件夹 如果被创建文件夹的父文件夹不存在,则抛出NoSuchFileException. 如果被创建的文件夹已经存在,则抛出FileAlreadyExistsException. 如果因为磁盘IO出现异常,则抛出IOException. 代码语言:javascript 代码运行次数:0 运行 AI代码解释 Path path = Paths.get("D:\data222\test"); Path...
Files.createFile(Path path):创建文件。 Files.delete(Path path):删除文件或目录(如果为空)。 代码语言:javascript 代码运行次数:0 运行 AI代码解释 Path newFile=Paths.get("/home/user/newfile.txt");Files.createFile(newFile);Files.delete(newFile); ...
Returns the pathname string of this abstract pathname's parent, or null if this pathname does not name a parent directory. FilegetParentFile() Returns the abstract pathname of this abstract pathname's parent, or null if this pathname does not name a parent directory. StringgetPath() Converts...
