Customer Data: Area Codes

• Assume you work for a company that tracks customer information, including name, gender and phone numbers
• Your company has a file called customers.txt which contains the following information:

• Half of the 16 customers in this file have a phone number with an 831 area code.
• Half have a phone numbers have a 408 area code.

• Write a program that reads in all of the customer information using a loop, and stores the names of the customers in two different string arrays - each array of length 8.
• One array should store the customers with a 408 area code and one array should store the customers with an 831 area code.

• When the customers are stored in each array, they should be stored as Mr., Ms. or Mx. depending on the gender below their name in the file.
• In other words, whenever the customers.txt file contains an M below the customer name, you should place the word Mr. before the name.
• Whenever the customers.txt file contains an F below the customer name, you should place the word Ms. before the name.
• Finally, whenever the file contains an O below the customer name, you should place the word Mx. before the name.

• You must also capitalize each name by calling the capitalizeName method.
• I recommend calling capitalizeName before storing the name inside the array.

• Finally, you will be required to write the two arrays to a file.
• Each array should be written to a different file.
• The 408 area code array should be written to a file called SJCustomers.txt
• The 831 area code array should be written to a file called SCCustomers.txt
• You must write the arrays to the file by calling the printArray method.
• Note that you will need to call printArray twice - once for each array.
• Important: Your solution must only use concepts and methods covered in this class to receive credit.

Method requirements

• capitalizeName Method:

  • The method is named capitalizeName

  • It take in an array of Strings

  • It capitalizes all of the letters in each String of the array

  • This method must use a for loop. It cannot call any outside methods that we have not discussed in this class.

  • It returns nothing.

• printArray Method:
  • The method is named printArray
  • It throws IOException
  • It takes in two parameters:
    • the first parameter is an array of Strings,
    • the second parameter is a String for the name of a text file in which to write out the data
  • The method must open the file whose name is passed in as a parameter
  • It declares a PrintWriter and uses it to write to the specified file
  • It uses a for loop to print out the contents of the array in the file, with each element on its own line
  • It then closes the PrintWriter.
  • It returns nothing.
• On the final, you will be required to write a the complete method, including its signature, and a Javadoc comment for each method
• The method signature is provided below but will not be provided on the final.

• Copy and paste the starter code below into a new class called AreaCodes.java

/*

import java.io.*;
import java.util.Scanner;

public class AreaCodes {
  
   public static void main(String[] args) throws IOException {
       String name, gender, phone;

        //Declare your two arrays here - one per area code
      

        //Declare File and Scanner

        //Below variables to keep track of array index in loop

       int i = 0;
       int j = 0;
       while(??????) {

            //read in name and gender

          

            //if statements related to gender

          

            //read in phone

          

            //if statements for phone

          
       }

        //call capitalizeNames method twice

      

        //call printArray method twice

        //close Scanner

      
   }

    

          //write Javadoc comment here

   public static void capitalizeNames(String[] names) {

        return;

   }

    

          //write Javadoc comment here

   public static void printArray(String[] names, String fileName){//throw IOException

       return;

   }
}

• Below is the output that your program should give inside of the SJCustomers.txt file

MS. JIMING WU
MS. LEANNA PEREZ
MR. MOHAMMED ABBAS
MS. KUMARI CHAKRABARTI
MR. SHAKIL SMITH
MR. PEDRO MARTINEZ
MX. ALLY GU
MR. ALVIN NGO

• It should also give the below is the output in a second file called SCCustomers.txt file

MR. JAMES BROWN
MR. XING LI
MX. STACEY CAHILL
MS. JUNG AHRIN
MS. TAMARA WHITE
MR. ABIR FADEL

MR. BRAD FEINMAN

Answer 1

Following is the complete code for the above problem:

/*
* @author
* CIS 36A
*/
import java.io.*;
import java.util.Scanner;

public class AreaCodes {
  
public static void main(String[] args) throws IOException {
String name, gender, phone;

//Declare your two arrays here - one per area code
String[] names_408 = new String[8];
String[] names_831 = new String[8];

//Declare File and Scanner
File f = new File("customers.txt");
Scanner scan = new Scanner(f);
//Below variables to keep track of array index in loop

int i = 0;
int j = 0;
while(scan.hasNextLine()) {

//read in name and gender
      name = scan.nextLine();
      gender = scan.nextLine();
      String prefix = null;

//if statements related to gender
      if(gender.equals("M") || gender.equals("m")) {
          name = "mr. " + name;   
      }else if(gender.equals("F") || gender.equals("f")) {
          name = "ms. " + name;   
      }else {
          name = "mx. " + name;   
      }
  

//read in phone
      phone = scan.nextLine();
  

//if statements for phone
      if(phone.startsWith("408")) {
          names_408[i++] = name;
      }else {
          names_831[j++] = name;
      }
  
}

//call capitalizeNames method twice
capitalizeNames(names_831);
capitalizeNames(names_408);

//call printArray method twice
printArray(names_408, "SJCustomers.txt");
printArray(names_831, "SCCustomers.txt");
//close Scanner
scan.close();
  
}

  

//write Javadoc comment here

public static void capitalizeNames(String[] names) {
   for(int i = 0;i<names.length;i++) {
       names[i] = names[i].toUpperCase();
   }
return;
}

  

//write Javadoc comment here

public static void printArray(String[] names, String fileName) throws IOException{//throw IOException
   FileWriter fw = new FileWriter(new File(fileName));
   for(int i = 0;i<names.length;i++) {
       String line = names[i] + "\n";
       fw.write(line);
//System.out.println(line);
   }
   fw.close();
return;
}
}

After running the following program with the given file, the output file are as follows:
