Im trying to play an audio file in a program. I had it working but when i went to convert it into a class it wont work.

1. song song;
   
   void setup (){
     song = new song();
   }
   
   void draw(){
     song.play();
   }
   
   
   

1. import ddf.minim.*;
   //import processing.core.*;
   
   class song {
     Minim minim;
     AudioPlayer song;
   
     song() {
     }
   
     void play()
     {
       size(100, 100);
      
   song
   
       // this loads mysong.wav from the data folder
       song = minim.loadFile("12.wav");
       song.play();
     }
   
     void draw()
     {
       background(0);
     }
   
     void stop()
     {
       song.close();
       minim.stop();
   
       super.stop();
     }
   }
