Contoh Program Perpustakaan Sederhana Java Netbeans

Tugas Mandiri

2. Buat Program Perpustakaan Mahasiswa
User memasukan data (namaMhs, nim, jumlahbukupinjam, judulbBuku, jenis, biayapinjam)
Program menampilkan :

• (namaMhs, nim, jumlahbukupinjam, judulbBuku, jenis,
biayapinjam
• Total biaya ⇨ dihitung dari penjumlahan biayapinjam per masing
buku
• Jenis ⇨ jenis buku (1. Buku Komputer, 2. Buku Non Komputer)
• biayapinjam ⇨ • ketentuan jika jenis buku komputer, biaya pinjam =  5.000/buku
                           • ketentuan jika jenis buku non komputer, biaya pinjam = 3.000 /buku
