Question

PLEASE DO THIS IN JAVA!Design (pseudocode) and implement (source code) a program (name it PhoneBill) that calculates the bill for a cellular telephone company. The company offers two types of service: regular service and premium service. The rates vary depending on the type of service. The rates are computed as follows: Regular service: $15.00 fee covering first 50 minutes. Charges for over 50 minutes are computed at the rate of $0.50 per minute. Premium service: $25.00 fee plus: a. For daytime calls (between 6:00AM to 6:00PM), the first 50 minutes are free; charges for over 50 minutes are computed at the rate of $0.20 per minute. b. For nighttime calls (between 6:00PM to 6:00AM), the first 100 minutes are free; charges for over 100 minutes are computed at the rate of 0.10 per minute. The program prompts the user to enter an account number, a service code (of type char), and the number of minutes the service was used. A service code r (or R) means regular service; while code p (or P) means premium service. If the service is premium (code p or P), the customer may be using the service during both the day and night. Therefore, the program must ask the user to input the number of minutes used during daytime and nighttime in separate prompts. Document your code and properly label the input prompts and the outputs as shown below. Sample run 1: Account Number: 12345 Service type: Regular Total minutes: 50 Amount due: $15.00 Sample run 2: Account Number: 32145 Service type: Premium Daytime minutes: 40 Nighttime minutes: 200 Amount due: $35.00 Sample run 3: Account Number: 78654 Service type: Premium Daytime minutes: 60 Nighttime minutes: 120 Amount due: $29.00

Answer:-

The below is the required source code for the given problem in JAVA

Code:-

import java.util.Scanner;

class PhoneBill{

public static void main(String[] args) {

Scanner in = new Scanner(System.in);

int account_number, total_due = 0;

char service_code;

System.out.print("Enter Account Number: ");

account_number = in.nextInt();

System.out.print("Enter Service code(R/P): ");

service_code = in.next().toUpperCase().charAt(0);

int minutes=0, daytime=0, nighttime=0;

if(service_code=='R'){

total_due = 15;

System.out.print("Number of minutes the service used: ");

minutes = in.nextInt();

if(minutes>50)

total_due += (minutes-50)*0.50;

}

else if(service_code=='P'){

total_due = 25;

System.out.print("Number of munutes used during the daytime: ");

daytime = in.nextInt();

System.out.print("Number of munutes used during the nighttime: ");

nighttime = in.nextInt();

if(daytime>50)

total_due += (daytime-50)*0.20;

if(nighttime>100)

total_due += (nighttime-100)*0.10;

}

else{

System.out.println("Invalid service code");

System.exit(0);

}

System.out.println("\n\nAccount Number:\t"+account_number);

System.out.println("Service type:\t"+(service_code=='R'?"Regular":"Premium"));

if(service_code=='R'){

System.out.println("Total minutes:\t"+minutes);

System.out.println("Amount due:\t$"+total_due);

}

else{

System.out.println("Total minutes during day time:\t"+daytime);

System.out.println("Total minutes during night time:\t"+nighttime);

System.out.println("Amount due:\t$"+total_due);

}

}

}

In the above code I done for first sample run for second sample run please change the values. If you find any difficulty with the code, please let know know I will try for any modification in the code. Hope this answer will helps you. If you have even any small doubt, please let me know by comments. I am there to help you. Please give Thumbs Up,Thank You!! All the best
