Java Programs - Parcel Charge Calculation (Slab System)

Mayur Transport Company charges for parcels as per the following tariff:

Write a program in Java to calculate the charge for a parcel, taking the weight of the parcel as an input.

import java.util.Scanner;
 
public class ParcelChargeCalculator {
    public static void main(String[] args) {
 
        Scanner sc = new Scanner(System.in);
 
        System.out.print("Enter parcel weight (in kg): ");
        double weight = sc.nextDouble();
 
        double charge = 0;
 
        if (weight <= 10) {
            charge = weight * 30;
        }
        else if (weight <= 30) {
            charge = (10 * 30) + ((weight - 10) * 20);
        }
        else {
            charge = (10 * 30) + (20 * 20) + ((weight - 30) * 15);
        }
 
        System.out.println("\nTotal Parcel Charge = Rs. " + charge);
 
        sc.close();
    }
}

Output 1 : 
  SAMPLE INPUT : 
Enter parcel weight (in kg): 8

 SAMPLE OUTPUT : 
Total Parcel Charge = Rs. 240.0

Output 2 : 
  SAMPLE INPUT : 
Enter parcel weight (in kg): 25

 SAMPLE OUTPUT : 
Total Parcel Charge = Rs. 700.0

Output 3 : 
  SAMPLE INPUT : 
Enter parcel weight (in kg): 40

 SAMPLE OUTPUT : 
Total Parcel Charge = Rs. 1150.0

Explanation

1. Input

• The user enters the parcel weight in kilograms.

2. Slab-wise Calculation

• Up to 10 kg

                        Charge = Weight × 30

• 11 to 30 kg

                        Charge = (10 × 30) + (Remaining × 20)

• Above 30 kg

                        Charge = (10 × 30) + (20 × 20) + (Remaining × 15)

3. Output

• Displays the total parcel charge.
