Below is a working Name class with the following behavior:

Constructor

A getFormal method that returns the first name followed by the last name (separated by a space)

A getOfficial method that returns the last name followed by a comma (and space), followed by the first name

toString and equals methods

A class (i.e., static) method named read that is passed a Scanner object and returns a Name object created f rom data (last and first names) read in from the scanner.

A main method that reads in Name objects, prints out the formal and official versions of the name and keeps count of how many names were processed.

import java.io.*; import java.util.*; class Name { public Name(String last, String first) { this.last = last; this.first = first; } public Name(String first) {this("", first);} public String getFormal() {return first + " " + last;} public String getOfficial() {return last + ", " + first;} public boolean equals(Name other) {return first.equals(other.first) && last .equals(other.last);} public String toString() {return first + " " + last;} public static Name read(Scanner scanner) { if (!scanner.hasNext()) return null; String last = scanner.next(); String first = scanner.next(); return new Name(last, first); } private String first, last; public static void main(String [] args) throws Exception { Scanner scanner = new Scanner(new File("names.text")); int count = 0; Name name = read(scanner); while(name != null) { System.out.println("formal: " + name.getFormal()); System.out.println("official: " + name.getOfficial()); System.out.println(); count++; name = read(scanner); } System.out.println("---"); System.out.println(count + " names processed."); } } 

Your job is to make the following changes:

Add a getInitials method that returnd a string consisting of the first and last initials, each followed by a period ('.').

Add the following logic to main:

Print out the Name object resd in using the toString method

Print out the Name's initials (using the getInitials method).

Add logic so that if two consecutive names match, and error message is printed.

The name of your class should be Name. Plase remove the public attribute from your class definition (CodeLab restriction).

For example, if the file names.text contains:

Edwards Steven Carter Joshua Carter Joshua Jackson Anthony Carter Barbara Evans Edward White Christopher White Christopher Taylor Michelle Baker Melissa Young Anthony Hall Michael 

the program should produce the following output:

name: Steven Edwards formal: Steven Edwards official: Edwards, Steven initials: S.E. name: Joshua Carter formal: Joshua Carter official: Carter, Joshua initials: J.C. Duplicate name "Joshua Carter" discovered name: Anthony Jackson formal: Anthony Jackson official: Jackson, Anthony initials: A.J. name: Barbara Carter formal: Barbara Carter official: Carter, Barbara initials: B.C. name: Edward Evans formal: Edward Evans official: Evans, Edward initials: E.E. name: Christopher White formal: Christopher White official: White, Christopher initials: C.W. Duplicate name "Christopher White" discovered name: Michelle Taylor formal: Michelle Taylor official: Taylor, Michelle initials: M.T. name: Melissa Baker formal: Melissa Baker official: Baker, Melissa initials: M.B. name: Anthony Young formal: Anthony Young official: Young, Anthony initials: A.Y. name: Michael Hall formal: Michael Hall official: Hall, Michael initials: M.H. --- 12 names processed.

My code:

import java.io.*;

import java.util.*;

class Name {

public Name(String last, String first) {

this.last = last;

this.first = first;

}

public Name(String first) {this("", first);}

public String getFormal() {return first + " " + last;}

public String getOfficial() {return last + ", " + first;}

public boolean equals(Name other) {return first.equals(other.first) && last .equals(other.last);}

public String toString() {return first + " " + last;}

public static Name read(Scanner scanner) {

if (!scanner.hasNext()) return null;

String last = scanner.next();

String first = scanner.next();

return new Name(last, first);

}

public String getInitials() {

return Character.toUpperCase(first.charAt(0)) + "." + Character.toUpperCase(last.charAt(0))+".";

}

private String first, last;

public static void main(String [] args) throws Exception {

Scanner scanner = new Scanner(new File("names.text"));

int count = 0;

Name name = read(scanner);

while(name != null) {

System.out.println("name: " + name);

System.out.println("formal: " + name.getFormal());

System.out.println("official: " + name.getOfficial());

System.out.println("initials: " + name.getInitials());

System.out.println();

count++;

name = read(scanner);

}

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

System.out.println(count + " names processed.");

}

}

I want need help with printing

Duplicate name "Christopher White" discovered when the same name is scanned.

Print the exact output in the question
