Nama : Maheswara Danendra Satriananda

NRP : 5025201060

Kelas : PPB - F

Pada tugas 4 ini saya membuat aplikasi sederhana Roll Dice . Aplikasi berupa implementasi dari sebuah dice roller yang dapat menampilkan gambar dice dengan 6 kemungkinan sisi. Penyesuaian dan pembuatan dari aplikasi ini mengikuti video tutorial yang telah disampikan pada kelas. Berikut adalah source code yang saya miliki
