UTS PBO

Pada hari ini, saya membuat program sistem parkir elektronik dengan java. berikut hasil dan source codenya.

Class Main

 import java.util.Scanner;  
 /**  
  * Write a description of class Main here.

 public class Main  
 {  
   public static void main(String args[])  
   {  
     Scanner scan = new Scanner(System.in);  
     int menu, harga;  
     harga = 2000;  
     SistemParkir tiket = new SistemParkir(harga);  
     System.out.println("Silahkan pilih tombol yang di inginkan \n");  
     System.out.println("Pos Masuk Parkir");  
     System.out.println("1. Parkir");  
     System.out.println("2. Bantuan\n");  
     System.out.println("Pos Keluar Parkir");  
     System.out.println("3. Scan Barcode Keluar");  
     System.out.println("4. Print Bukti Parkir");  
     int tipe=1;  
     while(tipe == 1)  
     {  
       menu = scan.nextInt();  
       switch(menu)  
       {  
         case 1:  
         System.out.println("Masukkan Waktu Parkir (contoh : 1700) : ");  
         int awal = scan.nextInt();  
         tiket.masukparkir(awal);  
         tiket.Tiketparkir();  
         break;  
         case 2:  
         System.out.println("Harap menunggu operator");  
         break;  
         case 3:  
         System.out.println("Masukkan Waktu Keluar Parkir (contoh 1800) : ");  
         int akhir = scan.nextInt();  
         tiket.keluarparkir(akhir);  
         tiket.Scanbarcode();  
         break;  
         case 4:  
         tiket.buktiparkir();  
         tipe=0;  
         break;  
       }  
     }  
   }  
 }  

Class SistemParkir

 /**

 public class SistemParkir  
 {  
   private int tiket;  
   private int masuk;  
   private int biaya;  
   private int keluar;  
   public SistemParkir(int harga)  
   {  
     masuk = 0;  
     biaya = harga;  
   }  
   public void Tiketparkir()  
   {  
     System.out.println("##############");  
     System.out.println("Selamat Datang");  
     System.out.println("Waktu Parkir : "+masuk);  
     System.out.println("############");  
   }  
   public int masukparkir(int awal)

     return masuk=awal;  
   }  
   public void keluarparkir(int akhir)  
   {  
     keluar = akhir;  
     akhir -= masuk;
     akhir = akhir/1000;  
     biaya += akhir*1000;  
   }  
   public void Scanbarcode()  
   {  
     System.out.println("Biaya Parkir : Rp "+biaya);

     System.out.println("Rp. "+biaya);  
     System.out.println("#############");

 }  

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

Auction
