Get the path of a file via file explorer

Question

First of all I'm sorry if this question has been asked before or if there is documentation about the topic but i didn't found anything. I want to make a windows app that open windows file explorer and you can browse for and then select a mp3 file, so you can play it (and replay it) in this program. I know how to open file explorer, this is my code :

import java.awt.Desktop; import java.io.File; import java.io.IOException; public class Main { public static void main(String[] args) throws IOException { Desktop desktop = Desktop.getDesktop(); File dirToOpen = null; try { dirToOpen = new File("c:\\"); desktop.open(dirToOpen); } catch (IllegalArgumentException iae) { System.out.println("File Not Found"); } } }

But i don't know how to select an mp3 file and then get the path of the file, so i can play it later.

I don't think you are approaching this right. You should use something like a FileDialog to choose a file:

FileDialog fd = new FileDialog(new JFrame()); fd.setVisible(true); File[] f = fd.getFiles(); if(f.length > 0){ System.out.println(fd.getFiles()[0].getAbsolutePath()); }

Since you are only getting 1 MP3 file, you only need the first index of the File array returned from the getFiles() method. Since it is a modal dialog, the rest of your application will wait until after you choose a file. If you want to get multiple files at once, just loop through this aforementioned Files array.

See the documentation here: https://docs.oracle.com/javase/7/docs/api/java/awt/FileDialog.html

@MikeBaranczak Thanks for the heads up. Got a little lazy there.
Yeah, i didn't knew about FileDialog. This is a good solution. Thanks a lot !
@A.Sharma I'd like to add that you have to set the multiple files through FileDialog.setMultipleMode(bool); however, this only applies for JDK7 and above. link
