Contoh program GUI

Assalamu'alaikum Warahmatullahi Wabarakatuh

Selamat datang kembali teman-teman, semoga kalian sehat selalu dan jangan lupa bersyukur dalam kondisi apapun.

Kembali lagi di blog ilyasakti, kali ini kita akan membuat program tentang Graphical User Interface (GUI) pada Java. Nah untuk pembahasan GUI, bisa cek di blog yang sebelumnya ya..

Daripada kelamaan, yuk kita cekicus.....

Program 1

Seperti biasa kalian buka aplikasi JCreator atau Netbeans kalian, setelah itu create file dengan nama Perpus.. Nah kalo sudah, kalian bisa sruput program dibawah ini hehe :D.

import javax.swing.*;

public class Perpus extends JFrame{
//sisipkan deklarasi objek disini
JLabel lblKodeBk = new JLabel("Kode Buku :");
JLabel lblNamaPm = new JLabel("Nama Peminjam :");
JLabel lblLamaPm = new JLabel("Lama Pinjaman :");
JLabel lblJudulBk = new JLabel("Judul Buku :");

JTextField txtKodeBk = new JTextField();
JTextField txtNamaPm = new JTextField();
JTextField txtLamaPm = new JTextField();
JTextField txtJudulBk = new JTextField();

JButton cmdTambah = new JButton("Tambah");
JButton cmdUbah = new JButton("Ubah");
JButton cmdHapus = new JButton("Hapus");
JButton cmdBersih = new JButton("Bersih");

//konstruktor MatKul
public Perpus(){
setTitle(".:: Form Peminjaman Buku Perpustakaan ::.");
setSize(450,230);
setLocationRelativeTo(this);

//atur layout form agar dapat menampilkan objek di dalam
getContentPane().setLayout(null);

//atur letak objek di layar monitor(x,y,width,height)
lblKodeBk.setBounds(10,20,100,25);
lblNamaPm.setBounds(10,50,100,25);
lblLamaPm.setBounds(10,80,100,25);
lblJudulBk.setBounds(10,110,100,25);

txtKodeBk.setBounds(120,20,100,25);
txtNamaPm.setBounds(120,50,300,25);
txtLamaPm.setBounds(120,80,100,25);
txtJudulBk.setBounds(120,120,100,25);

cmdTambah.setBounds(10,150,80,25);
cmdUbah.setBounds(110,150,80,25);
cmdHapus.setBounds(210,150,80,25);
cmdBersih.setBounds(310,150,80,25);

//menambahkan objek ke form
getContentPane().add(lblKodeBk);
getContentPane().add(lblNamaPm);
getContentPane().add(lblLamaPm);
getContentPane().add(lblJudulBk);

getContentPane().add(txtKodeBk);
getContentPane().add(txtNamaPm);
getContentPane().add(txtLamaPm);
getContentPane().add(txtJudulBk);

getContentPane().add(cmdTambah);
getContentPane().add(cmdUbah);
getContentPane().add(cmdHapus);
getContentPane().add(cmdBersih);

//membersihkan tampilan form
bersih();
show();
}
void bersih(){
//mengosongkan teks
txtKodeBk.setText("");
txtNamaPm.setText("");
txtLamaPm.setText("");
txtJudulBk.setText("");

//membuat teks bisa diedit
txtNamaPm.setEditable(true);
txtLamaPm.setEditable(true);
txtJudulBk.setEditable(true);

//menaktifkan tombol
cmdTambah.setEnabled(true);
cmdUbah.setEnabled(true);
cmdHapus.setEnabled(true);
cmdBersih.setEnabled(true);

//menempatkan kursor pada teks kode
txtKodeBk.requestFocus();
}
//method main
public static void main (String[] args) {
new Perpus();
}
}

Hasil output program

Kurang lebihnya seperti itu. Lanjooootttt........

Program 2

Pada program ke 2 ini rada beda sama contoh diatas ya. Jangan lupa create file kayak diatas ya tapi ini dengan nama file FormBioskop. Programnya?nih dibawah ya..

Output program

Program 3

Pada program ke 3 ini rada ribet karena kita pakai netbeans untuk desainnya lalu ngoding isinya. Create project untuk membuatnya.

Nah kalian pilih Java Application ya untuk membuatnya. Setelah itu akan tampil seperti dibawah, silahkan isi nama project kalian dan class nya ya. Baru setelah semua fix klik finish.

Kira-kira nanti tampilannya akan seperti ini, setelah itu kalian klik kanan pada nama project kalian terus pilih new lalu JFrame Form.

Lalu kalian isi tampilan seperti ini, setelah itu klik finish untuk konfirmasi.

Nah setelah selesai finish, nih tampilannya dan tools untuk kalian mendesain program Java yang kalian inginkan.

Desain awal seperti ini ya.

Berikut program ketika dijalankan via JCreator
