Cost Estimator Program

Project Objectives:

• Write a program that produces a road trip cost estimator with a GUI interface.
• Using miles for distance, dollars per gallon for gasoline cost, and miles per gallon for gas mileage.

Steps taken:

1. Created a grid pane and set its properties
2. Set alignment of nods within pane
3. Set Horizontal & vertical gaps between nodes
4. Place nodes in the pane
• 0,0 Distance Label node – 1,0 Distance (input) textField node – 2,0 Miles/kilometers Cost ComboBox node
• 0,1 Gasoline Cost Label – 1,1 Gasoline Cost (input) textField node – 2,1 Dollars per gallon/dollars per liter ComboBox node
• 0,2 gas mileage Label node – 1,2 gas mileage (input) textField node – 2,2 miles per gallon/ kilometers per liter ComboBox node
• 0,3 Number of Days Label node – 1,3 Number of Days (input) textField node
• 0,4 Hotel Cost Label node – 1,4 Hotel Cost (input) textField node
• 0,5 Food Cost Label node – 1,5 Food Cost (input) textField node
• 0,6 Attractions Label node -1,6 Attractions (input) textField node
• 0,7 Button node ”Calculate” – 1,7 setOnAction to output totalCost
• 0,8 Total Trip Cost Label node – 0,8 Total Trip Cost(output) textField node does not take in input
5. Create scene and place it in the stage ( Title: Trip Cost Estimator)
6. Method calculateTotalCost()
• Convert numerical strings into Doubles and return string that describes each key code (getText())
• Distance, gasCost, gasMileage, hotelCost, foodCost, days, attractions, totalGasolineCost, totalTripCost.
7. Include mesument conversions for :
• kilometers
• dollars/liter
• kilometers/liter
8. Add calculations to get total trip cost
• gasoline cost = 𝑑𝑖𝑠𝑡𝑎𝑛𝑐𝑒 𝑔𝑎𝑠 𝑚𝑖𝑙𝑎𝑔𝑒 – gasoline cost total trip cost = gasoline cost + (hotel cost + food cost) number of days + attractions
