Hello, i need help on how to create a JLabel as a status bar that display count representing the number of each shape display
in addition i need to create a class called MyShape and make it a superclass

this my code for for al shapes :

package Lab8;

import java.awt.Color;
import java.awt.Graphics;
import java.util.Random;
import javax.swing.JPanel;

public class DrawPanel extends JPanel {

	// declare instance variables
	private Random randomNumbers = new Random ();
	private MyLine lines [];
	private MyRectangle rects [];
	static final long serialVersionUID = 0;

	// the constructor
	public DrawPanel () {
		// declare local variables
		final int NUMBER_COLORS = 256;	// (0-255 color values)
		final int WINDOW_WIDTH = 300, WINDOW_HEIGHT = 300;
		int x1, y1, x2, y2;
		Color color;
		boolean fill;
		
		
		// set background color
		setBackground (Color.WHITE);
		
		// allocate the arrays  (5 to 9 references)
		lines = new MyLine [5 + randomNumbers.nextInt (5)];
		rects = new MyRectangle [5 + randomNumbers.nextInt (5)];
		
		// create the MyLine objects
		for (int count = 0; count < lines.length; count++) {
			// generate random coordinates (0 to 299)
			x1 = randomNumbers.nextInt (WINDOW_WIDTH);
			y1 = randomNumbers.nextInt (WINDOW_HEIGHT);
			x2 = randomNumbers.nextInt (WINDOW_WIDTH);
			y2 = randomNumbers.nextInt (WINDOW_HEIGHT);
			
			// generate a random color
			color = new Color (randomNumbers.nextInt (NUMBER_COLORS),
										randomNumbers.nextInt (NUMBER_COLORS),
											randomNumbers.nextInt (NUMBER_COLORS));
			
			// construct a MyLine object
			lines [count] = new MyLine (x1, y1, x2, y2, color);
		}  // end for loop to create MyLine objects

		// create the MyRectangle objects
		for (int count = 0; count < rects.length; count++) {
			// generate random coordinates (0 to 299)
			x1 = randomNumbers.nextInt (WINDOW_WIDTH);
			y1 = randomNumbers.nextInt (WINDOW_HEIGHT);
			x2 = randomNumbers.nextInt (WINDOW_WIDTH);
			y2 = randomNumbers.nextInt (WINDOW_HEIGHT);
			
			// generate a random color
			color = new Color (randomNumbers.nextInt (NUMBER_COLORS),
										randomNumbers.nextInt (NUMBER_COLORS),
											randomNumbers.nextInt (NUMBER_COLORS));
			fill = randomNumbers.nextBoolean ();
			
			// construct a MyRectangle object
			rects [count] = new MyRectangle (x1, y1, x2, y2, color, fill);
		}  // end for loop to create MyRectangle objects

	}  // end drawPanel constructor
	
	
	// when time to paint the panel, draw the lines, rectangles, and ovals
	public void paintComponent (Graphics g) {
		// paint the parent first

}

thanks for that

my question is how do i connect the MyOval class with the rest of the classes so it would count the rectangles and lines ?

to what class as example i need refer to ?

part of my instruction are to create no argument constructor , and a constructor that takes the argument necessary to initialize its instance variables
and a to string method that return a string representation of my shape object

Thats the requirements
i didn't get your last explanation i didn't figure it out

do i need to write a new class? to modify the variables in the draw panel or do i need to write it in the draw panel itself

i am international student so sometimes the english is little hard to understand i am a visual learner if i see code i understand it immediately
