JAVA Help
Create a do-while loop / with switch case statements that operate the program.
You will have multi-level menu operation using do-while implementation.
Present the user with a menu and options. Based upon the options selected by the user the program should operate correctly. You will need nested menu’s of some sort.
Create a computer program that will calculate the range for 3 different vehicles.
The program should create a “programmer created” class, where 3 int class/instance variables are created passengers, fuel capacity, mpg.
Set-up the program so the user can manually input the values for passengers, fuel capacity, mpg for the 3 created vehicles.
Use programming conventions void set() methods to set values, return get() methods to return values.
Think about where in the program in object creation will take place.
range = fuel capacity * miles per gallon.
Each Vehicle type should have unique values for number of passengers, fuel capacity, and miles per gallon.
Attach Snipping photos as the program operates, including menu prompts, outputs etc.
Please create White Boarding or Pseudo Code for you program design.
Sample Output: // Create similar output for 3 Vehicle Types
On next page-
Change input values now that we are creating the same program multiple times.
