How to get rid of the file type when using getName()?

Only doing this because I am lazy. I just wrote a program to list all my music into an excel file.

   import java.io.*;
   import org.apache.commons.io.FileUtils;

      public class NewClass {

        public static void main( String args[] ) 
        {
           File folder = new File("C:/Users/Public/Music/OldMusic");
           File[] listOfFiles = folder.listFiles();

            for (int i = 0; i < listOfFiles.length; i++) {
             try{
                 FileUtils.writeStringToFile(new File("test.xls"), listOfFiles[i].getName(), true);
                 BufferedWriter output;
                 output = new BufferedWriter(new FileWriter("test.xls", true));
                 output.newLine();
                 output.close();
             }
             catch (IOException e){
             }
          }
      }
     }

The code works fine, but at the end of every song there is .mp3 (i.e.: Metallica - Nothing Else Matters.mp3).

Is there a way just to have the Name of the song without the .mp3 at the end of it?

Since you're already using FileUtils, note that you get methods for handling extensions.

See FileUtils.removeExtension.

Look through the code and you'll see that these methods for handling filename extensions - also getExtension, isExtension - all just use lastIndexOf, so they'll only handle the simple cases, but this should be sufficient for your purposes.

Use:

String fname = listOfFiles[i].getName();
fname.substring(0, fname.lastIndexOf("."))

Instead of passing..

listOfFiles[i].getName()
