1. Aplikasi Program Komputer Grafik
Saya Menggunakan 14 Kelas Dalam membuat aplikasi ini :
1. Utama 8. Tank
2. Menu 9. Orang
3. Design 10. LaunchProgressBar
4. Arc 11. empaJam
5. Oval 12. GrafikGempa
6. Roundrect 13. ImageZoomer
7. Rect 14. ImageZoomerFrame

1. Program yang Pertama Kelas Utama
Source :
import javax.swing.JDesktopPane;
import java.awt.Graphics;
import java.awt.Graphics2D;
import java.awt.Image;
import javax.swing.ImageIcon;
import java.util.logging.Level;
import java.util.logging.Logger;
public class utama extends JDesktopPane {
protected void paintComponent(Graphics g) {
try {
Graphics2D graphics = (Graphics2D) g.create();
Image img = new ImageIcon(getClass().getResource("kayu2.jpg")).getImage();
graphics.drawImage(img, 0, 0, getWidth(), getHeight(), null);
graphics.dispose();
}catch ( Exception e ){
System.exit(0);
}
}
public static void main ( String [] args ) {
LaunchProgressBar pb = new LaunchProgressBar();
pb.setVisible(true);
for(int i=0;i<=100;i++)
try {
pb.getProgressBar().setValue(i);
Thread.sleep(100);
} catch (InterruptedException ex) {
Logger.getLogger(LaunchProgressBar.class.getName()).log(Level.SEVERE, null,ex); }
pb.dispose();
new menu(); } }

Proses :
- Saya Menggunakan import java.awt.* dan import javax.swing.* dalam kelas ini.
- Lalu saya menggunakan gambar kayu2.jpg sebagai background pertama program
ketika di jalankan
- Lalu saya menggunakan progress bar sebagai tambahan pada saat loading ke program
sebagai background pertama sebelum program berjalan sepenuhnya.
- Class ini hanya sebagai kelas induk atau kelas utama karena Ketika class ini di
jalankan maka langsung akan memangil kelas menu karena di method main nya
terdapat new menu().

Output :
Output ini adalah proses dari LaunchProgressBar yang membuat tampilan loading menjadi
lebih menarik
Ini tampilan dari Menu utama

Proses :
- Saya menggunakan beberapa component toolbar , JButton , JmenuBar , Jmenu
,JmenuItem ,Jmenu , dan DesktopPane dalam class ini .,
- Masing-masing component tersebuat adlaha sebagai berikut :
- Toolbar berfungsi untuk menampung button.
- Jbutton Berfungsi untuk memanggil class-class lain seperti arc , rect ,roundrect dll.
- Jmenubar, Jmenu dan JMenuItem berfungsi unutk menampilkan about yang berada
paling atas.
- DesktopPane berfungsi untuk menampilkan gambar kayu2.jpg yang tadi telah di buat
di class utama.

}

Proses :
- Saya menggambat grafik empat jam.
- Untuk Background saya menggunakan warna hitam yang di tandai dengan
setBackground(Color.black);
- Saya juga menggunakan 7 method dalam class ini yang mempunyai fungsi masing-
masing. Seperti method init yang berfungsi untuk mengatur size dan background , lalu
method start yang berfungsi untuk menjalankan jarum jam,lalu ada method stop yang
berhentikan jarum jam , lalu ada method run yang berfungsi mengambil jam detik dan
menit dari komputer kita , lalu ada drawHand , drawWedge, drawRoundedNum yang
masing” berfungsi untuk menggambarkan grafik 4 jam tersebut.

}

Proses :
- Dalam class program ini saya memasukkan beberapa komponent seperti Jlist , jButton
dan jTextField.
- Serta saya membuat array String untuk menampung nama gambar yang telah di
simpan.
- Pada program ini user di persilahkan untuk memilih gambar mana yang akan di
perbesar dengan kelipatan 10 atau nilai bisa di input sendiri oleh user sesuai
keinginan.
- Setelah itu gambar yang telah di pilih oleh user akan di tampilkan di frame baru.

Proses :
- Dalam class ini saya menggunakan 6 komponen seperti Jpanel , jbutton ,Jlabel
,ScrollPane,imagePanel dan cursor .
- Dalam class program ini adalah sambungan class dari imagezoom yang sebelumnya .
dimana dalam class ini hanya menampilkan gambar yang telah di pilih oleh user
dalam class imagezoom.

Proses :
- Saya Menggunakan import java.awt.* dan import javax.swing.* dalam kelas ini.
- Dalam class ini saya menggunkan 2 komponen yaitu Panel dan Label.
- Dimana panel ini berfungsi untuk menampung setiap komponen yang saya buat ,
sedangkan untuk masing text yang tampil saya menggunakan label.
