• • Example: Create variables: monthlySales Prompt user for their monthly sales Wait for user and then save user input in variable monthlySales If monthlySales variable > 60000 ⚫ -Display message to user: You have earned a $1000 bonus Homework #4 - Based on Chapter 3 (Parts 1 and 2 lectures) Green Fields Landscaping Company sells evergreen trees which are priced by height. Customers have a choice of purchasing a tree and taking it home with them or purchasing a tree and having it delivered. Write a program that asks the user the number of trees purchased, the height of the trees, and if they want the trees delivered. Based on that information the program should then generate an invoice. Assume that ALL the trees purchased by a customer are the same height. Tree Pricing Information Under 3 Feet Tall 39.00 (tax included) 3 to 5 Feet Tall 69.50 (tax included) 6 to 8 Feet Tall 99.00 (tax included) Over 8 Feet Tall 199.50 (tax included) Additional Fee for Delivery If the number of trees purchased is less than five the delivery fee is 10.00 * the number of trees purchased If the number of trees purchased is five or more the delivery fee is 50.00 Your program should ask the user for the following information: -Number of Trees the customer would like to purchase -Tree height to the nearest foot (have them enter it as a whole number - so no fractional tree heights) -If the trees will be delivered -Ask if the trees will be delivered using the following prompt: Will the trees be delivered? Enter 1 for Yes, Enter O for No. -Do NOT use chars for input - your program will break due to some things I haven't shown you yet and you won't pass the Hypergrade test cases. Once your program has the user input it should calculate the tree cost, delivery cost and total cost and display an invoice for the user (see below). Your program will need the following variables (note that some of these are required and some of these are suggested variables (and you may need some additional variables besides these)), if you figured out a way to do the program using different variables that is OK): • a Scanner type variable named keyboard to read in user input (remember Scanner is REQUIRED, no Dialog Boxes for this one) • a DecimalFormat type variable named formatter to format output (DecimalFormat is REQUIRED, no System.out.printf) ⚫ an int type variable named forDelivery to hold the value 1 to indicate that Yes the trees will be delivered or to hold the value 0 to indicate that No the trees won't be • delivered (do NOT use a char as it will cause problems I haven't showed you how to fix yet). The user should be prompted to enter 1 or 0 to indicate their choice regarding delivery. an int type variable named numTrees to hold user input on the number of trees they want to purchase (the user cannot buy fractional trees) • a int type variable named treeHeight (remember for simplicity we said assume the user enters a whole number for the tree height) to hold user input on the height of the trees they want to purchase (remember all trees purchased are assumed to be the same height) • a double type variable named single Tree to hold the cost of one tree • a double type variable named treeCost to hold the total cost of the all trees purchased • (treeCost = num Trees * cost for one tree (single Tree variable above) at the treeHeight the customer is purchasing trees at HINT: You will need to use an if-else-if statement to determine the cost of one tree based on its height • a double type variable named deliveryCost to hold the delivery costs (if any) for the trees • HINT: Initialize the variable delivery Cost to zero in case there are no delivery costs HINT: You will need an if-else statement to determine delivery charges for the case when numTrees is less than 5 and the case when num Trees is greater than or equal to 5 • a double type variable named totalCharges to hold the total charges for the trees (totalCharges = treeCost + deliveryCost) Any other variables you need Your program should output an invoice in the following format (look at the output in the "view required solution" link for exact output): Green Fields Landscaping Evergreen Tree Invoice 4 Trees at 99.00 each: $396.00 Delivery Charge: TOTAL: $ 0.00 $ 396.00 Make sure and test your program for cases with delivery, cases without delivery and with cases different numbers of trees.
