sorry wrong explanation..actually i can click the checkbox n radiobutton but when i want to calculate it..means i click the receipt button...terminal error occur...

i try to put the bg image at my gui..but still i don't know where the coding should put it..someone can help me?

thanks you guys for the info about the background..i manage to make it..but still there problem with my gui..no error after compile..but my receipt,clear n reset button got problem ....i really stuck and don't know how to fix it...

fix is

// DONUT text field
	private JTextField tfChocOreo = new JTextField("0");
	private JTextField tfPeanut = new JTextField("0");
	private JTextField tfStrawberry = new JTextField("0");
	private JTextField tfVanilla = new JTextField("0");
	private JTextField tfBlueberry = new JTextField("0");

	// ADDITIONAL FOOD Text Field
	private JTextField tfCorn = new JTextField("0");
	private JTextField tfSoup = new JTextField("0");
	private JTextField tfSandwich = new JTextField("0");

	// DRINK text field
	private JTextField tfPepsi = new JTextField("0");
	private JTextField tfMountain = new JTextField("0");
	private JTextField tfFn = new JTextField("0");

and

// get the quantity DONUT
		int p1 = (tfChocOreo.getText().trim().equals("")) ? 0 : Integer
				.parseInt(tfChocOreo.getText());
		int p10 = (tfPeanut.getText().trim().equals("")) ? 0 : Integer
				.parseInt(tfPeanut.getText());
		int p11 = (tfStrawberry.getText().trim().equals("")) ? 0 : Integer
				.parseInt(tfStrawberry.getText());
		int p12 = (tfVanilla.getText().trim().equals("")) ? 0 : Integer
				.parseInt(tfVanilla.getText());
		int p13 = (tfBlueberry.getText().trim().equals("")) ? 0 : Integer
				.parseInt(tfBlueberry.getText());

		// Get the quantity for ADDITIONAL FOOD
		int p2 = (tfCorn.getText().trim().equals("")) ? 0 : Integer
				.parseInt(tfCorn.getText());
		int p21 = (tfSoup.getText().trim().equals("")) ? 0 : Integer
				.parseInt(tfSoup.getText());
		int p22 = (tfSandwich.getText().trim().equals("")) ? 0 : Integer
				.parseInt(tfSandwich.getText());

		// get the quantity for DRINK
		int p3 = (tfPepsi.getText().trim().equals("")) ? 0 : Integer
				.parseInt(tfPepsi.getText());
		int p31 = (tfMountain.getText().trim().equals("")) ? 0 : Integer
				.parseInt(tfMountain.getText());
		int p32 = (tfFn.getText().trim().equals("")) ? 0 : Integer
				.parseInt(tfFn.getText());

hope this helps

thx 4 your helps..but still the receipt,clear,n reset button cannot function..i really don't know what the problem..maybe because of the import??i will try to fix it..

the problem lies here

txtReceipt.append("MEMBERSHIP DISCOUNT 10%" + "\t\t" + " - RM"
						+ df.format(discount) + "\n");
				txtReceipt.append("TOTAL PAYMENT" + "\t\t\t" + " RM"
						+ df.format(rbRegular) + "\n");
				txtReceipt.append("\n");
				txtReceipt.append("\t THAN

the rbRegular is a radio button and has no double or integer value in it....

fix that yourself and let us know...

i've tried it..but the terminal error still occur..i think i'm going crazy..hahaha..but thanks a lot for your helps..
is it package that i use is correct?
