Your job is to reformat each record as follows:

last_name, first_name, email Killby, Norry 

Starter Code:

package contactlistupdater;

import java.io.FileNotFoundException;

import java.io.IOException;

import java.nio.file.Paths;

import java.util.Formatter;

import java.util.Scanner;

import sun.reflect.generics.reflectiveObjects.NotImplementedException;

public class ContactListUpdater {

private static final String INPUT_FILENAME = "contacts.txt";

private static final String OUTPUT_FILENAME = "updated-contacts.txt";

/**

* Transforms a String containing a contact entry to a new format

*/

public static String processContactEntry(String input) {

// TODO your code here...

return input;

}

public static void main(String[] args) {

// Open input/output files and process line by line

try (Formatter output = new Formatter(OUTPUT_FILENAME)) {

try (Scanner input = new Scanner(Paths.get(INPUT_FILENAME))) {

// Process each line

while (input.hasNextLine()) {

output.format("%s%n",

processContactEntry(input.nextLine()));

}

System.err.println("Unable to open input file: " +
