Java kode 

 JFrame window = new JFrame(Title);
         
         getTitle = Title;
         
         if (MAX == true) {
             window.setExtendedState(window.MAXIMIZED_BOTH);
         } 
         
         if (MAX == false) {
             window.setSize(size_1, size_2);
         }
         
         if (borderless == true) {
             window.setUndecorated(true);
             
         }
 
         if (borderless = false) {
             
         }
         
         p = new JPanel();
         p.add(new ZinXan_AQUA());
         
         window.add(p, BorderLayout.CENTER);
         window.setLocationRelativeTo(null); 
         window.setVisible(vis);

Java kode 

 package GUI;
 
 import java.awt.*;
 import javax.swing.*;
 
 public class ZinXan_AQUA extends JPanel {
     private static final long serialVersionUID = 1L;
 
     public void paintComponent(Graphics g) {
         super.paintComponent(g);
 
         Graphics2D g2d = (Graphics2D) g;
         g2d.drawString("Java 2D", 50, 50);
         
         
     
     }
