Java Program: Calculate the Parcel Charge based on the Weight Slabs

28. 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 ParcelCharge {
    public static void main(String[] args) {
        Scanner sc = new Scanner(System.in);
 
        int weight;
        double charge = 0;
 
        System.out.print("Enter the weight of the parcel (in Kg): ");
        weight = sc.nextInt();
 
        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("Total Parcel Charge = Rs. " + charge);
    }
}

Sample Run 
Enter the weight of the parcel (in Kg): 35
Total Parcel Charge = Rs. 775.0

Calculation

• First 10 kg → 10 × 30 = 300
• Next 20 kg → 20 × 20 = 400
• Remaining 5 kg → 5 × 15 = 75
• Total = Rs. 775

✅ Explanation

• The program takes the parcel weight as input using Scanner.
• It uses an if–else ladder to apply slab-wise charges:
• First slab charged fully before moving to the next.
• The final charge is displayed in rupees.
