Imitate a cash register transaction

swoo23 · #1 24-Sep-2008, 09:33

Hi I've been reading around the forums and I've decided to join. I'm a new student in computing and I was wondering if someone could help me out.

Create a Java application project called Exercise1b that imitates a cash register transaction. You should enter the price of the item at the keyboard, calculate the gst (5%) on that price, calculate the total amount due, get the amount tendered from the keyboard, calculate the change due and print out all the results with two decimal places. The output should look like the following (note that user input is in bold type):

Use the following code to input the price and the amount tendered:

JAVA Code:

System.out.print("Please enter the item price>");
Float itemPrice = Keyboard.in.readFloat();

System.out.print("Please enter the amount tendered>");
Float amtTendered = Keyboard.in.readFloat();

Please enter the item price>4.98

Price: 4.98

GST: 0.25

Total: 5.23

Please enter the amount tendered>6.25

Tender: 6.25

Change due: 1.02

How would I write that out?

Senior members might not reply to this thread if you:

used "Please help", "C problem" or something equally vague as the title for your thread.
included example code in your message and not use the syntax highlighting [cpp], [java] etc. tags.
did not describe the problem accurately or include the error message (if any).

The guidelines for posting can be found here.

We encourage you to post again once you've done that.

# You must use Float objects and float primitive data types to complete this exercise.
# See Floats and floats for more details
# Convert Float from readFloat() to float value to do any math operation, for example:

JAVA Code:

 Float itemPrice = Keyboard.in.readFloat();
 float fItemPrice;
 fItemPrice = itemPrice.floatValue();

# You can convert the float value, fItemPrice into a float value with two decimal places using the expression:

JAVA Code:

    Math.round(fItemPrice*100f)/100f

Those are the guidelines that I am supposed to follow.

The thing is, I'm really new at this and I was wondering how I would start this code? I'm not sure how I would calculate the GST and the others.

I also use eclipse to write these codes if that helps.
