Java 'file.delete()' 不删除指定的文件 [英] Java 'file.delete()' Is not Deleting Specified File

问题描述

这是目前我必须删除的文件，但它不起作用.我认为这可能是权限问题或其他问题，但事实并非如此.我正在测试的文件是空的并且存在，所以不知道为什么不删除它.

This is currently what I have to delete the file but it's not working. I thought it may be permission problems or something but it wasn't. The file that I am testing with is empty and exists, so not sure why it doesn't delete it.

UserInput.prompt("Enter name of file to delete");
String name = UserInput.readString();
File file = new File("\Files\" + name + ".txt");
file.delete();

非常感谢任何帮助！

我现在有:

File file = new File(catName + ".txt");
String path = file.getCanonicalPath();
File filePath = new File(path);
filePath.delete();

尝试在运行时找到正确的路径，以便在将程序转移到另一台计算机时仍能找到该文件.

To try and find the correct path at run time so that if the program is transferred to a different computer it will still find the file.

推荐答案

一定要找出你当前的工作目录，并写下你的文件路径.

Be sure to find out your current working directory, and write your filepath relative to it.

此代码:

File here = new File(".");
System.out.println(here.getAbsolutePath());

... 将打印出该目录.

... will print out that directory.

此外，与您的问题无关，请尝试使用 File.separator 来保持与操作系统无关.反斜杠仅适用于 Windows.

Also, unrelated to your question, try to use File.separator to remain OS-independent. Backslashes work only on Windows.
