This is my Java/NetBeans assignment. I am going to try to work it out on my own, but if my code doesn't work, I'd like to have the correct code to reference:
- Only use the default file for your code - do not create a new class!
- Add a constant value for the tax rate - 8%
- In the 'main' method file add the following:
- Using the JOptionPane Class, ask the user for the cost on an item.
- Use this answer for the rest of the program
- Do not create three JOptionPanes, only one for user input and one for output.
- Convert the users answer to a double number.
- Create one string that has results from all three methods (method requirements are below)
- Create one JOptionPane to display the results. For example - if the user enters 35.25, the output could look like this:
- Create three overloaded methods each with the name ComputeBill that will do the following:
- First overloaded method - Calculate the cost including tax
- Pass the cost of the item
- Calculate the taxes on the item based on the tax rate.
- Return thecost including tax
- Second overloaded method - Calculate the cost including tax for 4 items
- Pass the cost of the item and the number of that item sold
- You do not have to ask the user for this number, just pass 4 for the quantity.
- Calculate the taxes on the items based on the tax rate.
- Return thecost including tax for 4 items
- Third overloaded method - Calculate the cost including tax for 4 items with a $20 coupon
- Pass the cost of the item, the number of that item sold, and the the coupon value.
- You do not have to ask the user for this number, just pass 20.00 for the coupon value.
- The coupon amount is removed from the cost BEFORE you calculate the tax.
- Calculate the taxes on the items based on the tax rate.
- Return thecost including tax for 4 items with a $20 coupon.
