How do I open the file selection box and only choose songs with the extension .mp3?

I am using Windowbuilder but the menu does not provide such option for quick creation.

    Take a look here: https://docs.oracle.com/javase/tutorial/uiswing/components/filechooser.html. Well, I believe this is the path of stones to your doubt.

    Despite a little poorly formulated the question, it is possible to answer yes within the context asked. For this I voted to leave open.

According to these two answers found in Soen:

Selecting the file types

You’ll need the method getDescription and accept, example:

JFileChooser fileChooser = new JFileChooser();

fileChooser.setFileFilter(new FileFilter()
{
   public String getDescription() {
       return "Audio Files (*.mp3)";
   }

   public boolean accept(File f) {
       if (f.isDirectory()) {
           return true;
       } else {
           String filename = f.getName().toLowerCase();
           return filename.endsWith(".mp3");
       }
   }
});

I have not tested the code yet, but it seems to work, please let me know if there is any problem.
