 Ets kali ini membuat tiket parkir elektronik atau manless. Saya menggunakan 2 class yaitu

1. Class Main
2. Class Ticket
.
Untuk source code class main =

 /**  
  * Source code class main  
  *  
  * @author (Chaniyah Zulfa Mukhlishah)  
  * @version (15/10/2018)  
  */  
  import java.util.Scanner;   
  public class main   
  {   
   public static void main(String args[])   
   {   
    Scanner scan = new Scanner(System.in);   
    int vehicle,saldo,lama_parkir;   
    String plat;   
    System.out.println("Welcome to parking area");   
    System.out.println("-------------------------------");   
    System.out.println("Pilih Kendaraan: ");   
    System.out.println("1. Motor");   
    System.out.println("2. Mobil");  
    System.out.print("Kendaraan yang diparkir: ");   
    vehicle = scan.nextInt();  
    Ticket tick= new Ticket(vehicle);  
    System.out.print("Masukkan nomor plat anda : ");   
    plat = scan.next();   
    tick.masukkan_plat(plat);  
    System.out.print("Masukkan lama waktu parkir (dalam jam): ");   
    lama_parkir = scan.nextInt();   
    tick.masukkan_durasi(lama_parkir);  
    System.out.print("Masukkan saldo anda: Rp ");   
    saldo = scan.nextInt();   
    tick.masukkan_saldo(saldo);  
    System.out.println("--------------------------------------");  
    if(vehicle == 1)  
   {   
    System.out.println("Kendaraan yang anda parkir adalah Motor");  
    System.out.println("Tarif : Rp 3000/jam. Tarif yang anda bayar: Rp " + lama_parkir*3000);   
   }  
    else if(vehicle == 2)  
   {  
    System.out.println("Kendaraan yang anda parkir adalah Mobil");  
    System.out.println("Tarif : Rp 5000/jam. Tarif yang anda bayar: Rp " + lama_parkir*5000);   
   }   
    System.out.println("Ketik '0' untuk mencetak karcis");   
    int perintah = scan.nextInt();  
    if(perintah== 0)  
     {tick.printTicket();}   
   }     
  }   

.
Untuk source code class ticket :

   {   
    vehicle = jenis;    
   }   
   public void masukkan_saldo(int uang)

   public void printTicket() //1=motor, 2=mobil   
   {   
    if(vehicle == 1)   
    {   
     if (saldo > 0)   
     {   
      if (saldo >= hargamotor*lama_parkir)   
      {   
       System.out.println('\u000C');   
       System.out.println("KARTU PEMBAYARAN PARKIR");   
       System.out.println("===============================");   
       System.out.println("Durasi parkir: " + lama_parkir + " jam");   
       System.out.println("Kendaraan: Motor");   
       System.out.println("Plat nomor: " + plat);    
       System.out.println("Tarif: Rp " + hargamotor*lama_parkir);   
       int kembalian_mot = saldo - hargamotor*lama_parkir;   
       System.out.println("Kembalian saldo anda: Rp " + kembalian_mot);   
      }  
      else   
      {   
       System.out.println("Saldo anda tidak mencukupi, isi saldo terlebih dahulu, atau jangan parkir sini ya");   
      }   
     }   
    }   
    else if(vehicle == 2)   
    {   
     if (saldo > 0)   
     {   
      if (saldo >= hargamobil*lama_parkir)   
      {   
       System.out.println('\u000C');   
       System.out.println("KARTU PEMBAYARAN PARKIR");   
       System.out.println("===============================");   
       System.out.println("Durasi parkir: " + lama_parkir + " jam");   
       System.out.println("Kendaraan: Mobil");   
       System.out.println("Plat nomor: " + plat);    
       System.out.println("Tarif: Rp " + hargamobil*lama_parkir);   
       int kembalian_mob = saldo - hargamobil*lama_parkir;   
       System.out.println("Kembalian saldo anda: Rp " + kembalian_mob);   
      }  
      else

      }   
     }

Music Organizer dan Pelelangan

Nama = Chaniyah Zulfa Mukhlishah

NRP   = 05111740000115

Kelas  = PBO-B

Tugas rumah kali ini adalah membuat Music Organizer untuk mengatur dan memutar lagu, dan satu lagi adalah membuat proses pelelangan.

1. MUSIC ORGANIZER
Pada tugas ini, membutuhkan 2 class, yaitu = Class Music Organizer dan Class Music Player.

--------------------------------------------------------------------------------------------------------------------------

Saat kita menge-Run pada Class Music Organizer, tampilan awal adalah =

--------------------------------------------------------------------------------------------------------------------------

karena belum dibuat playlist, lalu kita membuatnya dengan memilih fungsi 'TambahFile' pada class Music Organizer, dan kita bisa menambahkan lagu/musik yang kita inginkan dengan penambahan awal adalah index ke nol

----(index ke 0)----

----(index ke 1)----

----(index ke 2)----

--------------------------------------------------------------------------------------------------------------------------

Untuk memanggil list yang tersimpan, gunakan fungsi 'listFile' pada class Music Organizer , lalu inputkan index lagu/music

--------------------------------------------------------------------------------------------------------------------------

Untuk menjalankan lagu, gunakan fungsi 'startPlaying' pada class Music Organizer, pilih lagu dengan inputkan nomor/index lagu

--------------------------------------------------------------------------------------------------------------------------

Untuk memberhentikan lagu, gunakan fungsi 'stopPlaying' pada class Music Organizer

--------------------------------------------------------------------------------------------------------------------------

     files = new ArrayList<>();  
     player = new MusicPlayer();  
   }

   {  
     files.add(filename);

   {  
     System.out.println(" Music berhenti diputar ");  
   }  
 }  

--------------------------------------------------------------------------------------------------------------------------

2. PELELANGAN

Pada tugas ini, membutuhkan 4 class, yaitu =

  - Lot = Barang yang di perjual belikan

  - Bit = Tawaran

  - Person = SI Penawar

--------------------------------------------------------------------------------------------------------------------------

Input nama barang yang akan dilelang (diperjual belikan) , gunakan fungsi 'enterLot' pada Class Auction

, maka setelah di list akan keluar =

--------------------------------------------------------------------------------------------------------------------------

Masukkan nama penawar pada Class Person

--------------------------------------------------------------------------------------------------------------------------

Lalu, masukkan tawaran dari penawar(oran1 dan orang2) menggunakan fungsi 'makeABid' pada Class Auction

(Number 1 menunjukkan penawaran untuk jenis barang ke 1 yaitu Laptop)

--------------------------------------------------------------------------------------------------------------------------

Pelelangan sukses dan dari 2 penawar akan diambil yang menawar paling mahal, yaitu Chan dengan tawaran = 500366 pada laptop

--------------------------------------------------------------------------------------------------------------------------

Setelah proses selesai, maka pelelnagan ditutup menggunakan fungsi 'close' pada Class Auction, dan akan ditunjukkan hasil akhir dari lelangan.
