Membuat Aplikasi Penilaian Mahasiswa Dengan Chart Menggunakan Netbeans.
Menampilkan chart perhitungan nilai mahasiswa dengan bentuk chart garis
Cara Kerja :
Dengan
meng inputkan nilai kehadiran, nilai tugas, nilai uts, nilai uas kemudian klik
hitung dan tampilkan, lalu akan muncul
nilai akhir dan chart sesuai dengan nilai yang di inputkan. Dimana nilai (nilai akhir) dihitung dari:
Kehadiran x 10% +
tugas x 20% + UTS x 30% + UAS x 40%
