如何在java中扫描不同目录中的文件？ [英] How to scan a file in a different directory in java?

问题描述

例如：java文件位于C ：\Files\JavaFiles\test.java但是，我要扫描的文件位于C：\Data\DataPacket99\data.txt

注意：我已经尝试将另一个java文件放在C：\Data目录中，并使用test.java文件作为一个类，但它不起作用。它仍然尝试从C：\Files\JavaFiles目录扫描。

解决方案

通过使用绝对路径的一个亲戚。

 文件文件=新文件（C：\\\\DataPacket99\\\ \\data.txt）; 
  

然后，您可以使用InputStream或类似的方式编写访问该文件对象的代码。

How do you scan a file with java that isn't in the directory the java file is in?

For example: The java file is located at "C:\Files\JavaFiles\test.java" However, the file I want to scan is located at "C:\Data\DataPacket99\data.txt"

Note: I've already tried putting another java file in the "C:\Data" directory and using the test.java file as a class, but it doesn't work. It still tries to scan from the "C:\Files\JavaFiles" Directory.

解决方案

By using an absolute path instead of a relative.

File file = new File("C:\\Data\\DataPacket99\\data.txt");

Then you can write code that accesses that file object, using a InputStream or similar.
