Question 3

DTDC a courier company charges for the courier based on the weight of the parcel. Define a class with the following specifications:

class name: courier

Member variables:
name – name of the customer
weight – weight of the parcel in kilograms
address – address of the recipient
bill – amount to be paid
type – ‘D’ – domestic, ‘I’ international

Member methods:

void accept() – to accept the details using the methods of the Scanner class only.
void calculate() – to calculate the bill as per the following criteria:

Weight in Kgs

Rate per Kg

First 5 Kgs

Rs. 800

Next 5 Kgs

Rs. 700

Above 10 Kgs

Rs. 500

 

An additional amount of Rs. 1500 is charged if the type of the courier is I (International).
void print() – To print the details
void main() – to create an object of the class and invoke the methods.

 

Java 
import java.util.Scanner;
class courier{
    String name;
    double weight;
    String address;
    double bill;
    char type;
    public void accept(){
        Scanner in = new Scanner(System.in);
        System.out.print("Customer name: ");
        name = in.nextLine();
        System.out.print("Parcel weight in kg: ");
        weight = Double.parseDouble(in.nextLine());
        System.out.print("Address: ");
        address = in.nextLine();
        System.out.print("Parcel type: ");
        type = in.nextLine().charAt(0);
    }
    public void calculate(){
        if(weight <= 5)
            bill = weight * 800;
        else if(weight <= 10)
            bill = 4000 + (weight - 5) * 700;
        else
            bill = 7500 + (weight - 10) * 500;
        if(type == 'I' || type == 'i')
            bill += 1500;
    }
    public void print(){
        System.out.println("Customer name: " + name);
        System.out.println("Address: " + address);
        System.out.println("Parcel weight: " + weight);
        System.out.println("Parcel type: " + type);
        System.out.println("Bill = " + bill);
    }
    public static void main(String[] args){
        courier obj = new courier();
        obj.accept();
        obj.calculate();
        obj.print();
    }
}
