Write a java program that will read a sequence of names (first name followed by last name, separated by at least one space) from a text file and will 1) remove all duplicate names and 2) write the names (last name followed by a comma, followed by one space, followed by first name) in ascending order to a text file.

For example, if the input file contains:

Colette Sapienza

Gretta Beumer

Emmanuel Mossman

Colette Sapienza

Shawanda Hutt

Adriana Montilla

Marica Stanfill

Neva Shover

Tijuana Means

Adriana Montilla

Gerri Koenig

Kirsten Beres

The output file must contain:

Beres, Kirsten

Beumer, Gretta

Hutt, Shawanda

Koenig, Gerri

Means, Tijuana

Montilla, Adriana

Mossman, Emmanuel

Sapienza, Colette

Shover, Neva

Stanfill, Marica

Your program must contain and use the following methods:

public static int find

(ArrayList<String> names, int i)

Let s be names.get(i);

Looks for s beginning from position i+1. If s is found at a position j (j > i), return j. Otherwise return -1.

public static void

removeDuplicates(ArrayList<String> names)

Removes duplicates from ArrayList names

public static void

sort(ArrayList<String> names)

Sorts ArrayList names

You cannot use ArrayList’s sort method.

The main method must:

1. Prompt the user for the name of the input file with a meaningful message.

2. Prompt the user for the name of the output file with a meaningful message.
