Music Player

Pada kali ini, saya mendapat tugas untuk membuat program music organizer dengan java. Berikut source code dan hasil output programnya.

Class Music Organizer

 import java.util.ArrayList;  
 /**  
  *   
  *  
  * @author (Ismail)  
  * @version (14102018)  
  */  
 public class Musicorganizer  
 {  
   private ArrayList<String> files;  
   private Musicplayer player;  
   //membuat sebuah music organizer  
   public Musicorganizer()  
   {  
     files = new ArrayList<>();  
     player = new Musicplayer();  
   }  
   //menambahkan file ke koleksi  
   public void addFile(String filename)  
   {  
     files.add(filename);  
   }  
   //memasukkan jumlah file ke koleksi  
   public int getNumberOfFiles()  
   {  
     return files.size();  
   }  
   //list file dari koleksi  
   public void listFile(int index)  
   {  
     if(index >= 0 && index < files.size()){  
       String filename = files.get(index);  
       System.out.println(filename);  
     }  
   }  
   //menghapus file di koleksi  
   public void removeFile(int index)  
   {  
     if(index >= 0 && index < files.size()){  
       files.remove(index);  
     }  
   }  
   //memainkan file musik di koleksi  
   public void startPlaying(int index)  
   {  
     String filename = files.get(index);  
     player.startPlaying(filename);  
   }  
   //menghentikan player musik  
   public void stopPlaying()  
   {  
     player.stopPlaying();  
   }  
 }  

Class Music Player

 /**  
  *   
  *  
  * @author (Ismail)  
  * @version (14102018)  
  */  
 public class Musicplayer  
 {  
   private String music;  
   public Musicplayer()  
   {  
     music = null;  
   }  
   public void startPlaying(String filename)  
   {  
     music = filename;  
     System.out.println(music+ " Is Now Playing");  
   }  
   public void stopPlaying()  
   {  
     System.out.println("The Music Stop Playing");  
   }  
 }  

Hasil Output program

1. Menambahkan lagu ke playlist

2. Mengecek list lagu

3. Memainkan dan menghentikan lagu
