Can't play sound in my java game

Question

package com.first.serious.main.controls;

import java.io.BufferedInputStream;

import java.io.InputStream;

import javax.sound.sampled.*;


public class AudioPlayer {

private Clip clip;


public AudioPlayer(String path){
    try{

        AudioInputStream AIS = AudioSystem.getAudioInputStream(getClass().getResourceAsStream(path));
        InputStream bufferedIn = new BufferedInputStream(AIS);
        AudioInputStream audiostream = AudioSystem.getAudioInputStream(bufferedIn);

        /* AudioFormat baseFormat = AIS.getFormat();
        AudioFormat decodeFormat = new AudioFormat(AudioFormat.Encoding.PCM_SIGNED,
                                                    baseFormat.getSampleRate(),
                                                    16,baseFormat.getChannels(),
                                                    baseFormat.getChannels()*2,
                                                    baseFormat.getSampleRate(),false);

        AudioInputStream DAIS = AudioSystem.getAudioInputStream(decodeFormat,AIS);*/

        clip = AudioSystem.getClip();
        clip.open(audiostream);


    }catch(Exception e){
        e.printStackTrace();
    }
}

public void play(){
    if(clip == null) return;
    stop();
    clip.setFramePosition(0);
    clip.start();
}


public void stop(){
    if(clip.isRunning()) clip.stop();
}

public void close(){
    stop();
    clip.close();
}
}

Honestly, I just copied the code because I am a complete beginner in game developing. Already had two sets of code, the commented lines are from the first.

I used it in this class for mouseinputs

package com.first.serious.main.controls;

import com.first.serious.main.Shooter;
import java.awt.event.MouseEvent;
import java.awt.event.MouseListener;

public class MouseInput implements MouseListener{

   private Shooter game;
   private AudioPlayer deadsound;


   public MouseInput(Shooter game){
       this.game = game;
      deadsound = new AudioPlayer("/res/sounds/deadsound2.mp3");
   }
@Override
public void mouseClicked(MouseEvent me) {

}

@Override
public void mousePressed(MouseEvent me) {
    int mx = me.getX();
    int my = me.getY();
    //System.out.println(mx + " "  + my);
    if(game.state.equals("menu")){
        if(mx > 60 && mx < 330 && my > 200 && my < 280){
            deadsound.play();
            game.state = "game";
        }else
         if(mx > 60 && mx < 330 && my > 460 && my < 540){
            System.exit(0);
        }else
          if(mx > 60 && mx < 330 && my > 330 && my < 410){
              game.state = "help";
          }
    }
    if(game.state.equals("Dead")){
       // System.out.println("dead");
        if(mx > 60 && mx < 330 && my > 260 && my < 340){
            game.Score = 0;
            game.state = "game";
        }else
        if(mx > 60 && mx < 330 && my > 390 && my < 470){
            System.exit(0);
        }
    }

    if(game.state.equals("Upgrade")){
        if(mx > 60 && mx < 330 && my > 200 && my < 280){
            game.upgradectr = 0;
            game.player.XX += 0.5f;
            game.state2++;
            game.state = "game";
        }else
        if(mx > 60 && mx < 330 && my > 330 && my < 410){
            game.upgradectr = 0;
            game.getControl().Vy -= 1f;
            game.state2++;
            game.state = "game";
        }else
        if(mx > 60 && mx < 330 && my > 460 && my < 540){
             if(game.state2==05||game.state2==10||game.state2==20){
                game.upgradectr = 0;
                game.player.a += 2;
                game.state2++;
                game.state = "game";
            }else{   
                game.upgradectr = 0;
                System.out.println(game.upgradectr);
                game.getControl().reload -= 2;
                game.state2++;
                System.out.println(game.state2);
                game.state = "game";
             }
        }

    }else
    if(game.state.equals("help")){
        if(mx > 60 && mx < 330 && my > 460 && my < 540){
            game.state = "menu";
        }
    }
}

@Override
public void mouseReleased(MouseEvent me) {
}

@Override
public void mouseEntered(MouseEvent me) {
}

@Override
public void mouseExited(MouseEvent me) {
}

}

and then get these errors

java.lang.NullPointerException

I don't absolutely know what is the exact problem. I have the following jar libraries: mp3spi1.9.5.jar, jl1.0.1.jar and, tritonus_share.jar. Please help. Thank you.

directories

Please see the directories link for reference. thanks!. Realized the problem now, but haven't fully understood. I'm sorry guys, but my problem now is, how can I access the files from the sound folder while my java file is in the controls folder. I tried putting the file inside where the java file is and it worked. But I want my files to be organized as much as I could. Please Help thank you.
