Answer 1

import java.util.*;
class DTDC
{
 String name, address;
 double weight, bill;
 char type;
 public void accept()
 {
  Scanner sc=new Scanner(System.in);
  System.out.print("Enter the name of the customer:");
  name=sc.nextLine();
  System.out.print("Enter the weight of parcel in kilograms:");
  weight=sc.nextDouble();
  Sytem.out.print("Enter the address of the recipient:");
  address=sc.nextLine();
  System.out.print("Enter the type: D for domestic and I for international:");
  type=(char)sc.next().charAt(0);
 }
 public void calculate()
 {
 if(weight>0)
 {
 if(weight<=5)
   bill=800*weight;
  else if(weight<=10)
   bill=5*800+700*(weight-5);
  else
   bill=5*800+5*700+500*(weight-10);
 if(type=='I')
   bill+=1500;
  }
  else
   System.out.println("Invalid weight given");
 }
 public void print()
 {
   System.out.println("Name of the customer:"+name);
   System.out.println("Weight of the parcel:"+weight+"kilograms");
   System.out.println("Address of the recipient:"+address);
   System.out.println("Type of the parcel:"+type);
   System.out.println("Amount to be paid:"+bill);
 }
 public static void main(String arg[])
 {
   DTDC obj=new DTDC();
   obj.accept();
   obj.calculate();
   obj.print();
 }
}
