Java 

import java.util.*;
class ATransport{
    String name;
    int w;
    int charge;
    public void accept(){
        Scanner sc = new Scanner(System.in);

        name = sc.nextLine();
        System.out.print("Weight of the parcel in kg: ");
        w = sc.nextInt();
    }
    public void calculate(){
        if(w <= 10)
            charge = w * 25;
        else if(w <= 30)
            charge = 250 + (w - 10) * 20;
        else
            charge = 450 + (w - 30) * 10;
        charge += (int)(5.0 / 100 * charge);
    }

   public void print(){
        System.out.println("Name\tWeight\tBill Amount");
        System.out.println(name + "\t" + w + "\t" + charge);
    }
    public static void main(String args[]){
        ATransport obj = new ATransport();
        obj.accept();
