Tugas Pertemuan 5 Java Netbeans

Membuat program Kalkulator Sederhana dengan menggunakan Jframe!

Code:
Tombol Tambah

satu =Integer.valueOf(field1.getText());
dua =Integer.valueOf(field2.getText());
hasil=(satu+dua);
field1.setText(String.valueOf(hasil));
txthasil.setText(String.valueOf(hasil));
field2.setText(null);
field2.requestFocus();


Tombol Kurang

satu =Integer.valueOf(field1.getText());
dua =Integer.valueOf(field2.getText());
hasil=(satu-dua);
field1.setText(String.valueOf(hasil));
txthasil.setText(String.valueOf(hasil));
field2.setText(null);
field2.requestFocus();


Tombol kali

satu =Integer.valueOf(field1.getText());
dua =Integer.valueOf(field2.getText());
hasil=(satu*dua);
field1.setText(String.valueOf(hasil));
txthasil.setText(String.valueOf(hasil));
field2.setText(null);
field2.requestFocus();


Tombol Bagi

satu =Integer.valueOf(field1.getText());
dua =Integer.valueOf(field2.getText());
hasil=(satu/dua);
field1.setText(String.valueOf(hasil));
txthasil.setText(String.valueOf(hasil));
field2.setText(null);
field2.requestFocus();

Hasil :
