Langkah pertama
Buka aplikasi Netbeans > File>New project>Java>Java Aplication
Project Name isi gamepuzzle klik finish
Langkah kedua
di File package klik kanan>New>java class
hapus/delete semua syntak yang ada di java class kecuali package gamepuzzle
selanjutnya copykan syntak dibawah ini :
import javax.swing.JFrame;
class SlidePuzzle {
public static void main(String[] args) {
JFrame window = new JFrame("Slide Puzzle");
window.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
window.setContentPane(new SlidePuzzleGUI());
window.pack(); // finalize layout
window.show(); // make window visible
window.setResizable(false);
}
}
Langkah ke tiga
kembali lagi ke file package gamepuzzle klik kanan>new>JPanel Form
isi class name dengan nama SlidePuzzleGUI
selanjtnya hapus/delete semua syntaksnya dan copykan syntak di bawah ini :
