Get the filePath from Filename using Java

问题

Is there a easy way to get the filePath provided I know the Filename?

回答1:

You can use the Path api:

Path p = Paths.get(yourFileNameUri);
Path folder = p.getParent();

回答2:

Look at the methods in the java.io.File class:

File file = new File("yourfileName");
String path = file.getAbsolutePath();

回答3:

I'm not sure I understand you completely, but if you wish to get the absolute file path provided that you know the relative file name, you can always do this:

System.out.println("File path: " + new File("Your file name").getAbsolutePath());

The File class has several more methods you might find useful.

Correct solution with "File" class to get the directory - the "path" of the file:

String path = new File("C:\\Temp\\your directory\\yourfile.txt").getParent();

which will return:

path = "C:\\Temp\\your directory"
