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 :

int x1, y1, x2, y2;

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);

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
