Flip Bottom Half And Copy It To Produce Upper Half Of Shape

So my goal is to use the graphics class to draw this shape: [URL] ....

so far I've managed to draw the bottom half, but now I want to utilize the copyArea() method to flip the bottom half and copy it to produce the upper half of the shape: [URL] ....

and this is what I wrote to produce the bottom half:

import java.awt.Graphics;
/*

*/

public class MyFrame extends javax.swing.JFrame {

/**
* Creates new form MyFrame
*/
public MyFrame() {
initComponents();

[Code] .....
