Java Program: Menu Driven Program - Electric Taxi Fare Calculator

42. A new taxi service based on electric vehicles is offering services within a metro city. Following is the fare chart including the type of taxi used to commute and price per kilometer. Create a program to calculate total fare depending on the distance travelled in kilometers.

Type	Fare
Micro	10.05/Km
Macro	15.05/Km
Shared	7.05/Km

Java

import java.util.Scanner;
 
public class ElectricTaxiFare {
    public static void main(String[] args) {
 
        // Title
        System.out.println("ELECTRIC TAXI FARE CALCULATOR");
        System.out.println("-----------------------------");
 
        Scanner sc = new Scanner(System.in);
 
        double distance, farePerKm = 0, totalFare;
        int choice;
 
        System.out.println("Select Taxi Type:");
        System.out.println("1. Micro");
        System.out.println("2. Macro");
        System.out.println("3. Shared");
        System.out.print("Enter your choice: ");
        choice = sc.nextInt();
 
        System.out.print("Enter distance travelled (in km): ");
        distance = sc.nextDouble();
 
        switch (choice) {
            case 1:
                farePerKm = 10.05;
                break;
 
            case 2:
                farePerKm = 15.05;
                break;
 
            case 3:
                farePerKm = 7.05;
                break;
 
            default:
                System.out.println("Invalid taxi type selected!");
                sc.close();
                return;
        }
 
        totalFare = farePerKm * distance;
 
        System.out.println("Fare per Km   : Rs. " + farePerKm);
        System.out.println("Total Fare    : Rs. " + totalFare);
 
        sc.close();
    }
}

Output

Sample Output 

ELECTRIC TAXI FARE CALCULATOR
-----------------------------
Select Taxi Type:
1. Micro
2. Macro
3. Shared
Enter your choice: 2
Enter distance travelled (in km): 12
Fare per Km   : Rs. 15.05
Total Fare    : Rs. 180.6

📝 Explanation

User selects taxi type from the menu
User enters distance travelled
switch-case assigns the correct fare per km
Total fare is calculated using:

Total Fare = Distance × Fare per Km
