I provided 90 % of the program code for you in java.

I need the program modified to print out the full name at the end of the program.

while loops validate user input properly

Calculate costs for all three plans and save them in three variables which can be used for cost comparison. So if i bought plan a, display the amount of money you would save if bought plan b and c etc.

loop to display the 96 characters starting from the space character ' '. Display 16 characters on each line with one space between characters

import java.util.Scanner;

// define our class

public class BCS345hw1 {

public static void main(String[] args) {

// declare all variables

char phonePlan String fullName;

double minutesUsed;

double totalCharges = 0;

// create keyboard for the Scanner class

Scanner keyboard = new Scanner(System.in);

// menu that will display to the user about the type of phone plan to choose from

System.out.println(" Mobile Phone Service Plan");

System.out.println("----------------------------------------------------------");

System.out.println("Plan A: $39.99 per month. 450 free minutes. Additional usage costs $0.45 per minute.");

System.out.println(" Plan B: $59.99 per month. 900 free minutes. Additional usage costs $0.40 per minute.");

System.out.println(" Plan C: $69.99 per month. Unlimited minutes. ");

// prompts the user to enter their full name

System.out.print(" Please enter your full name: ");

fullName = keyboard.next().charAt(0);

// while loop that checks for user data validation

while (fullName == ' ') {

// if first name is null you will get this error message

System.out.println(" Thats not possible, try again: ");

fullName = keyboard.input.next();

}

// prompt the user to enter the package purchased

System.out.print("Which mobile service plan was purchased? (A,B, or C)? : ");

phonePlan = keyboard.next().charAt(0);

// while loop that test for data input validation

while (phonePlan != 'A' && phonePlan != 'a'

&& phonePlan != 'B' && phonePlan != 'b'

&& phonePlan != 'C' && phonePlan != 'c') {

// error message if your input doesnt match the cases for the phone plan

System.out.println(" You have entered the wrong phone plan "

+ "The package should be A or B or C only.");

phonePlan = keyboard.next().charAt(0);

}

// prompts the user to enter the amount of minutes used from last month

System.out.print("How many minutes did you use last month? :");

minutesUsed = keyboard.nextInt();

//while loop that checks user input if its negative

while (minutesUsed

//error message if minutes is negative

System.out.print("Error, minutes cant be negative :");

minutesUsed = keyboard.nextInt();

}

switch (phonePlan) {

case 'A':

case 'a':

// if package A was bought

if (minutesUsed

totalCharges = 39.99;

} else {

totalCharges = 39.99 + (0.45 * (minutesUsed - 450));

}

break;

case 'b': // if package B was bought

if (minutesUsed

totalCharges = 59.99;

} else {

totalCharges = 59.99 + (0.40 * (minutesUsed - 900));

}

case 'c':

// if package C was bought

totalCharges = 69.99;

break;

default: //if an invalid package is selected

System.out.println(" You have entered wrong option for package "

+ "The package should be A or B or C only.");

} // end switch

System.out.println(" Monthly Statement for " + fullName);

System.out.printf("Plan " + phonePlan + " Minutes used: " + "%.2f", minutesUsed);

System.out.println(" The charges are:" + " $" +totalCharges);

}

}

Monthly Statement for Alice Brown Plan - Minutes used: 555.00. The charges are $87. 24. By switching to Plan B you would save $27. 25. By switching to Plan C you would save $17.25. Task2: 0 1 2 3 4 5 6 7 8 9 ::-> ? ABCDEFGHIJKLMNO PQRSTUVTXYZ ". abcdefghijklmno DGI Stuvy: (1)
