Question
Objective: Find out the “true” MPG (Miles Per Gallon) of a vehicle, given a group of conditions which the user provides values for. 5 are given, 1 you create on your own. Requirements:
Prompt the user for the car’s MPG first. i.e. Please Enter MPG: 26
Then prompt the user to enter a value for six factors which will affect the MPG of the vehicle, prompting for single value inputs after showing menus (i.e. a series of println() statements showing the options/valid values to enter)
After collecting all of the inputs, provide a detailed report of the inputs, their meaning, how much they affect MPG, as well as the the beginning and final MPG.
The following criteria will be used for the six inputs.
City or Highway Driving: Use a boolean type variable for input
City Subtracts 2 from MPG
Highway Adds 5 to MPG
Rainy or Sunny: Use a String type variable for input
“Rainy” Subtracts 1 from MPG
“Sunny” No Change to MPG
Elevation: Use a char type variable for input
‘S’ for Steep, Steep Subtracts from 5MPG
‘H’ for Hilly, Hilly Subtracts 3 from MPG
‘F’ for Flat, No Change to MPG
Weight in Vehicle (cargo or passenger): Use double type for input
Each 100lbs subtracts 0.5 MPG
Speed Preference: Use an int type variable for input
1 for under speed limit, Add 2 to MPG
2 for at speed limit, No Change to MPG
3 for 5% above speed limit, Subtract 1 from MPG
4 for 10% above speed limit, Subtract 3 from MPG
5 for over 20% above speed limit, Subtract 5 from MPG
Suggestion: Use a switch() statement for Speed Preference
Add one additional factor which you will prompt the user for, that affects MPG such as
tire pressure/condition,
hybrid vs. gas powered,
engine condition,
towing load,
2WD/4WD,
