Tugas Pertemuan 12 Pemrograman Berbasis Objek (PBO) A 2024

Nama : Amadeo Yesa

NRP : 5025231160

Kelas : A

Tahun : 2024

Pada pertemuan 12, diberikan studi kasus sebuah sistem reservasi tiket pesawat yang mendukung tiga jenis kelas penerbangan:

• Ekonomi
• Bisnis
• First Class

Setiap kelas penerbangan memiliki perhitungan tarif yang berbeda-beda. Selain itu, setiap kelas juga memiliki kebijakan khusus, seperti fasilitas tambahan, batas bagasi, atau layanan yang disediakan.
