In Java, create a program that reads a file containing records for people. Then sort the list of people in ascending order (last name, first name) and then write the output to a new file.
** Here's the majority of the code for main method ** (Add in the necessary code and create the person class) import java.io.FileNotFoundException; import java.util.ArrayList; import java.util.Comparator; import java.util.Scanner; import java.io.File; import java.util.ArrayList; public class Main { public static ArrayList getFromFile(String filename) { // open the file //for each line //serialize into a person object //store into array list // return array list return(new ArrayList()); } public static void writeToFile(String filename, ArrayList persons) { // open file //for each person in persons // serialize to specified format //close file } public static void main(String[] args) { // String filename = "" ArrayList persons = getFromFile("10-01.person .csv"); persons.sort(new Comparator() { @Override public int compare(Person person1, Person person2) { //todo int comparison = person1.getLastName() .compareToIgnoreCase(person2.getLastName)()); if (comparison ==0){ comparison = person1.getFirstName() .compareToIgnoreCase(person2.getFirstName()); } // if (person1 > person2); return(1); // if (person1 writeToFile("10-01.person .csv", persons); ** Here's part of the contents of the 10-01.person.csv file ** (Create your own text file and implement it into the code)

To get started, you will need to create a Person class. The Plass will have three fields or attributes associated with it. ld-Contains the unique id for the person. Eg. a student id, a social security number, etc. LastName Contains the person's surname FirstName Contains the person's given name You will need to write the necessary constructors, getters and setters for the Person class fields. The constructors, getters and setter methods have NOT been explicitly specified but are still required. What you include or don't include is up to you. In addition, you will need to write the following methods (at a minimum): .getName0 Returns the name as a String value in "
, first> format. So for example my name would be output as "Heeres, George" without the quotes. equals)- Takes an instance of Person as a parameter and compares the lds of the Person objects for equality. We ONLY want to compare the id values. In most modern database systems, when we do equality checks, we are only checking the id values to determine equality. (eg. social security number, etc.) toString0 Returns the id and name in for following format. "[id> last>, first>" For example, if my id had been 11122565, the output would be: 11122565] Heeres, George Note: You probably want to leverage the getName) method to avoid writing duplicate code A file (10.01-person.ccontaining people has been provided for you. The file is in the standard CSV (comma separated values) format. The following is a small example from the file: id,first_name,last_name 0000080001,Lucienne, Harpur 0000080882, Karolina, Echallier 0000080803,Zaccaria, Grinstead 0000080004,Alyss, Lockey 0000080005, Gus, Brownsea 0000080006, Braden,McTerry 0000000007, Remington,Bilbee 0000080008, Elka, Robottom 0000880809, Modesta,Watterson You will notice that the first line of the file contains the column headers for the file. When reading the file, you will need to ignore this first line For each line read from the file, you will need to serialize the data into a Person object. Hint: Look at the String.split method. You will likely want to store this information as it's being read into an ArrayList of some sort. After the contents of the file have been sorted, you will need to sort the records in Last name followed by First name format. Assuming you have used an ArrayList of Person objects, you can use the .sort(0) method of the ArrayList class which requires an anonymous delegate. You will need to implement the compare) method of the Comparator interface. The compare method returns A negative integer if the first argument (person1) is less than the second argument (person2) A zero if the first argument (person1) is equal to the second argument (person2) A positive integer if the first argument (person1) greater than the second argument (person2) An example is provided below. You will need to implement the logic for the compare) method. Optionally, you can write your own sorting algorithm. A number of them have been provided in the book. ArrayList people - ...; people.sort(new Comparator) @0verride public int compare(Person person1, Person person2) //todo // f (person1 // f (person! // f (personi return 0 > person2); return(1); ,", You will need to write a header value to the file.
