Display a bill containing all the input data as well as the weekly day care fee, which is $55 for dogs weighing less than 15 pounds, $75 for dogs from 15 to 30 pounds inclusive, $105 for dogs from 31 to 80 pounds inclusive, and $125 for dogs weighing more than 80 pounds.

JAVA program is as follows.

import java.util.Scanner;  

import java.util.*;

public class Program{  

public static void main(String args[]){

   Scanner sc = new Scanner(System.in);

   int id;

   String name, breed;

   int age;

   double weight;

   int weekly_day_care_fee_15 =55;

   int weekly_day_care_fee_30 =75;

   int weekly_day_care_fee_80 = 105;

   int weekly_day_care_fee_greater =125;

   int weekly_day_care_fee=0;

   System.out.print("Enter id of dog's owner: ");

   id = sc.nextInt();

   System.out.print("Enter name of the dog: ");

   name = sc.next();

   System.out.print("Enter breed of the dog: ");

   breed = sc.nextLine();

   System.out.print("Enter age of the dog: ");

   age = sc.nextInt();

   System.out.print("Enter weight of the dog: ");

   weight = sc.nextDouble();

   if(weight<15)

       weekly_day_care_fee = weekly_day_care_fee_15;

   if(weight>=15 && weight<30)

       weekly_day_care_fee = weekly_day_care_fee_30;

   if(weight>=30 && weight<80)

       weekly_day_care_fee = weekly_day_care_fee_80;

   if(weight>=80)

       weekly_day_care_fee = weekly_day_care_fee_greater;

   System.out.println("");

   System.out.println(" BILL FOR WEEKLY DAY CARE OF DOGS ");

   System.out.println("");

   System.out.println("ID of dog's owner \t \t \t \t \t: "+id);

   System.out.println("Enter name of the dog \t \t \t \t: "+name);

   System.out.println("Enter breed of the dog \t \t \t \t: "+breed);

   System.out.println("Enter age of the dog \t \t \t \t: "+age);

   System.out.println("Enter weight of the dog \t \t \t: "+weight);

   System.out.println("The weekly day care fee of the dog  : $"+weekly_day_care_fee);

}

3. Variables are declared and initialized for all values of day care fees.

4. Multiple if statements are used to determine the fees based on the weight.
