Kode ini membuat sistem reservasi tiket pesawat yang mendukung tiga kelas penerbangan (Ekonomi, Bisnis, First Class), menghitung tarif berdasarkan kebijakan diskon atau tambahan biaya, dan menampilkan detail tiket yang dimasukkan oleh pengguna.
Superclass Ticket:
- Kelas abstrak yang berfungsi sebagai template dasar untuk semua jenis tiket.
- Memiliki atribut
passengerName(nama penumpang) danbaseFare(tarif dasar). - Metode abstrak
calculateFare()harus diimplementasikan oleh subclass. displayTicketDetails()menampilkan detail tiket.
Subclass EconomyTicket, BusinessTicket, FirstClassTicket:
- Masing-masing subclass mewarisi dari
Ticketdan mengoverride metodecalculateFare():EconomyTicket: Memberikan diskon 10% dari tarif dasar.BusinessTicket: Menambahkan biaya 25% ke tarif dasar.FirstClassTicket: Menambahkan biaya 50% ke tarif dasar.
- Setiap subclass menampilkan informasi tambahan seperti diskon atau biaya tambahan.
Kelas AirlineReservationSystem (Main Class):
- Menggunakan
Scanneruntuk membaca input dari pengguna: nama penumpang, tarif dasar, dan pilihan kelas. - Berdasarkan pilihan pengguna, program membuat objek dari kelas tiket yang sesuai.
- Menampilkan detail tiket menggunakan metode
displayTicketDetails(). - Menutup
Scanneruntuk menghindari kebocoran sumber daya.
