Pada Postingan blog kali ini saya akan memposting tentang membuat aplikasi sederhana mengunakan Java Netbeans dengan Report Wizard aplikasi yang di buat adalah aplikasi penjualan laptop,dimana aplikasi ini di gunakan untuk mempermudah para penjual laptop, dimana aplikasi ini dibuat untuk mempermudah para pembeli laptop mendapatkan laptop favorit dengan mudah dan membantu penjual laptop ditempat itu sendiri.
oke, untuk permulaan saya akan menampilkan flowchart terlebih dahulu,
Berikut contoh flowchart:
Berikut adalah penjelasan aplikasi sederhana yang saya buat dengan menggunakan Netbeans saya membuat aplikasi penjualan laptop dengan membuat from login terlebih dahulu
Untuk membuat sistem design login saya membutuhkan:
- 2 JLabel
- 2 JTextfiled
- 1 JPasswordfiled
- 2 Jbutton
Dan untuk mempercantik tampilan dengan menambahkan background saya menggunakan Jpanel , lalu saya pilih gambar yang sudah saya siapkan dan sesuai dengan aplikasi yang akan dibuat , atur letak gambar sebaik mungkin sehingga menjadi seperti gambar dibawah ini:
Berikut adalah source code yang saya gunakan untuk form login :
contoh :
BTN LOGIN
String a = txtpassword.getText();
if (a.equals("Lansmaulana")||a.equals("12345")){
JOptionPane.showMessageDialog(null, "Sukses","Informasi", JOptionPane.INFORMATION_MESSAGE);
dispose();
datapenjualanlaptop1 Frm=new datapenjualanlaptop1();
Frm.setLocationRelativeTo(Frm);
Frm.setVisible(true);
}else {
JOptionPane.showMessageDialog(null,"Username dan Password Salah","Informasi",JOptionPane.WARNING_MESSAGE);
}
}
setelah itu kita akan memasuki password yang salah apakah aplikasi akan menditek itu salah contoh seperti gambar dibawah :
Dan sekarang kita bisa mencoba memasuki password yang benar contoh gambar berikut:
Setelah kita sukses memasukkan kata sandi dengan benar akan muncul aplikasi untuk penginputan seperti gambar dibawah:
Untuk membuat desain saya membutuhkan:
- 4 Jtexfiled
- 2 Panel
- 6 Jlabel
- 5 Button
Ditempatkan dan diatur sedemikian rupa hingga menjadi seperti gambar diatas.
Kita bisa langsung menginput data laptop yang kita jual dengan memasukkan ke colum colum yang sudah tersedia ,seperti gambar dibawah :
Setelah itu ada pilihan hitung, dimana dalam hitung itu akan menghitung harga satuan akan dikalikan dengan jumlah barang yang kita beli dan akan muncul total bayar yang harus kita bayar.
Contoh codingan seperti gambar dibawah :
gambar
Untuk bisa seperti itu berikut source codenya :
BTN HITUNG
int a = Integer.parseInt(txtsatuan.getText());
int b = Integer.parseInt(txtjumlah.getText());
int hasilnya = a * b;
txttotal.setText(" " + hasilnya);
Tombol button hapus untuk menghapus semua text saat kita malas menghapus manual, maka kita hanya harus menekan tombol hapus, maka semua text akan hilang seperti tampilan awal.
seperti gambar dibawah ini:
Untuk button simpan digunakan untuk proses penyimpanan ke database , semua pesanan akan tersimpan di database sesuai dengan apa yang dipesan , jangan lupa untuk mengkoneksikannya ke database terlebih dahulu, sudah terkoneksi ke database di lokalhost sudah tersimpan seperti gambar dibawah ini:
Selanjutnya adalah button cetak, button cetak untuk menampilkan report wizard seperti gambar dibawah ini:
Untuk bisa menampilkan seperti gambar diatas, maka kita perlu membuat reportnya terlebih dahulu
dibawah ini saya akan menjelaskan cara pembuatannya.
Pertma kita buat projek baru di netbeans, dan menbuat file report wizard
seperti gambar dibawahini:
lalu akan muncul tampilan seperti gambar di bawah ini:
pilih layout kemudian klik next
lalu akan muncul gambar seperti di bawah ini:
isi semua sesuai dengan data anda, seperti yang terlihat pada gambar di atas lalu klik next,
lalu akan muncul seperti gambar di bawah ini:
pilih sesuai data anda di Mysql lalu klik ok
akan muncul seperti gambar di bawah ini:
Selanjutnya klik next :
klik tombol >> makan akan terjadi seperti gambar di atas
Lalu klik next :
Isi sesusai keinginan anda tetapi saya menyarankan isi satu group 1 saja selanjutnya klik next :
Jika sudah seperti gambar di atas maka anda telah berhasil membuat report wizard ,dan klik finis :
Dan jika ingin mengedit, kita aktifkan tombol designernya, dan untuk menambahkan tulisan atau
semacamnya, anda hanya perlu mengklik lalu menggesernya ini sudah bisa diaplikasikan di netbaens anda.
dan ini adalah semua source kodenya
