Answer»

(i) float amt, discount = 0.0;

int n = Integer.parselnt(TextNoofpens.getText());

amt = n * 25;

If (jSpeicalCustomer.isSelected() = = True)

{

discount = amt + 0.05;

amt = amt - discount;

}

jTextDiscount.setText(discount.toString());

jAmount.setText(amt.toString());

(ii) jNoofpens.setText(" ");

jTextDiscount.setText(" ");

jAmount.setText(" ");

jSpecialCustomer.setSelected(False);

(iii) System.exit(0);
