Program Penghitungan Indeks Prestasi Semester Mahasiswa (IP Semester)
Program Perhitungan IP Semester ini adalah program menghitung nilai mahasiswa dari beberapa mata kuliah yang diambil, dimulai dari meng input nama mahasiswa, NPM, Fakultas, Tahun Akademik dan Tanggal Pembuatan.
Dilanjutkan dengan menginput data mata kuliah, jumlah SKS dan nilai huruf yang diperoleh (mis: A, B, C, D, E) kemudian proses selanjutnya adalah meng klik tombol input untuk menampilkan mata kuliah, SKS dan nilai huruf pada tabel nilai.
Berikut ini adalah code yang diimbuhkan dalam tombol Input:
private void Input1ActionPerformed(java.awt.event.ActionEvent evt) {
// TODO add your handling code here:
//Menambahkan baris baru dengan inputan dari field
DefaultTableModel model= (DefaultTableModel)tabelNilai.getModel();
model.addRow(new Object[]{mataKuliahField.getText(),sksField.getText(),nilaiHurufField.getText()});
//Merubah nilai huruf menjadi nilai angka
int nilaiAngka;
if (nilaiHurufField.getText().equals("A")){
nilaiAngka= 4;
}
else if (nilaiHurufField.getText().equals("B")){
nilaiAngka= 3;
}
else if (nilaiHurufField.getText().equals("C")){
nilaiAngka= 2;
}
else if (nilaiHurufField.getText().equals("D")){
nilaiAngka= 1;
}
else nilaiAngka=0;
//Menghitung jumlah nilai dan nilai SKS lalu dikalkulasikan menjadi nilai IP
jumlahNilai= (nilaiAngka * Integer.parseInt(sksField.getText())) + jumlahNilai;
jumlahSKS= (Integer.parseInt(sksField.getText())) + jumlahSKS;
ip= jumlahNilai/jumlahSKS;
//Menset ipField dengan nilai dari ip
ipField.setText(String.valueOf(ip));
mataKuliahField.setText("");
sksField.setText("");
nilaiHurufField.setText("");
Untuk field mataKuliahField dan field-field lainnya sesuaikan dengan nama variabel yang berikan pada field itu. Selain itu jangan lupa untuk menambahkan variabel jumlahNilai, jumlahSKS, dan ip pada class tersebut dengan inisialisasi nilai nol dan beritipe double.
Untuk code program lengkapnya sebagai berikut :
