Sound Effects and .OGG usage?

I am currently working on a video game for my Java class, and I have hit a huge wall. I have no idea how to use audio in Java, and everything I have read online does not seem to work.

I really do not want to resort to using .mp3 files for my audio, but I guess learning how to use them may help me understand how to use .ogg files as well.
But now for the question:

Does anyone have a good method of playing sound effects and music that doesn't sound horrendous?

Hello Good Sir, I have a Java Class that does it all for you!

Here it is:

Code:

---

import java.io.*;
import java.net.URL;
import javax.sound.sampled.*;

public enum SoundEffects {
  EXPLODE("explode.wav"),
  HURT("hurt.wav"),
  PICKUP("pickup.wav"),
  POWERUP("powerup.wav"),
  BREAK("break.wav"),
  DISK_ONE("music/disk1.wav");

  public static enum Volume {
      MUTE, LOW, MEDIUM, HIGH
  }

  public static Volume volume = Volume.LOW;

  private Clip clip;
  private boolean isMusic = false;

  SoundEffects(String soundFileName) {
          if(soundFileName.toLowerCase().startsWith("disk")) {
                  isMusic = true;
          }else {
                  isMusic = false;
          }
      try {
        URL url = this.getClass().getClassLoader().getResource("sounds/" + soundFileName);
        AudioInputStream audioInputStream = AudioSystem.getAudioInputStream(url);
        clip = AudioSystem.getClip();
        clip.open(audioInputStream);
      } catch (UnsupportedAudioFileException e) {
        e.printStackTrace();
      } catch (IOException e) {
        e.printStackTrace();
      } catch (LineUnavailableException e) {
        e.printStackTrace();
      }
  }

  public void play() {
      if (volume != Volume.MUTE) {
        if (clip.isRunning())
            clip.stop();
        clip.setFramePosition(0);
        clip.start();
      }
  }

  static void init() {
      values();
  }
}

To use it, replace EXPLODE, HURT, etc with sound effects and the locations!
