Belajar plot berjalan di java

Dalam tulisan kali ini saya akan memberikan contoh source code java yang bisa digunakan dalam membuat plotting berjalan seperti yang dimaksud pada situs http://www.chem.mtu.edu/~tbco/cm416/newpida.html
(pastikan di komputer anda terinstal java untuk melihat simulasi yang dimaksud)
Untuk mencoba secara sederhana bagaimana algoritma yang digunakan dalam program tersebut, anda dapat mencoba source code berikut:

	public class AppFrame extends JFrame {
	public AppFrame(Component c, String title){
	super(title);
	this.setPreferredSize(new Dimension(700, 500));
	this.setLayout(new BorderLayout());
	this.add(c);
	this.pack();
	this.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
	this.setVisible(true);
	this.setResizable(false);
	}
	}
