Using a text editor, create a file that contains a list of at least 15 six-digit account numbers. Read in each account number and display whether it is valid. An account number is valid only if the last digit is equal to the remainder when the sum of the first five digits is divided by 10. For example, the number 223355 is valid because the sum of the first five digits is 15, the remainder when 15 is divided by 10 is 5, and the last digit is 5. Write only valid account numbers to an output file, each on its own line. Save the application as ValidateCheckDigits. java.

Explanation:

The following code is written in Java. It reads every input and checks to see if it is valid. If it is it writes it to the output file.

import java.io.File;

import java.io.FileNotFoundException;

import java.io.FileWriter;

import java.io.IOException;

import java.util.Scanner;

class {

           public static void main(String[] args) {

               try {

                   File myObj = new File("C:/Users/Gabriel2/AppData/Roaming/JetBrains/IdeaIC2020.2/scratches/input.txt");

                   Scanner myReader = new Scanner(myObj);

                   FileWriter myWriter = new FileWriter("C:/Users/Gabriel2/AppData/Roaming/JetBrains/IdeaIC2020.2/scratches/output.txt");

                   while (myReader.hasNextLine()) {

                       String data = myReader.nextLine();

                       int sum = 0;

                       for (int x = 0; x < 5; x++ ) {

                           sum += data.charAt(x);

                       }

                       int remainder = (sum % 10);

                       System.out.println(remainder);

                       System.out.println(data.charAt(5));

                       if (remainder == Integer.parseInt(String.valueOf(data.charAt(5)))) {

                           System.out.println("entered");

                           try {

                               myWriter.write(data + "\n");

                               System.out.println("Successfully wrote to the file.");

                           } catch (IOException e) {

                               System.out.println("An error occurred.");

                               e.printStackTrace();

                           }

                       }

                       sum = 0;

                   }

                   myWriter.close();

                   myReader.close();

               } catch (FileNotFoundException e) {

                   System.out.println("An error occurred.");

                   e.printStackTrace();

               } catch (IOException e) {

                   e.printStackTrace();

               }

           }

       }

given the lack of choices, i'm gonna wing it and say that pushing your car off a cliff might not be the best idea. your car might sustain damage from the fall and will probably result in the car being too damaged to jump start.

if that's not good enough, avoid filling the car with bees. bees might get agitated when trapped or during the moving process, and might result in death or painful stings that will make jump starting your car very difficult. but in the event that you do choose to fill your car with bees, remember to wear protective gear!
