Starter code for PhotoLineups.java

import java.util.Scanner;
import java.util.ArrayList;

public class PhotoLineups {

// TODO: Write method to create and output all permutations of the list of names.
public static void printAllPermutations(ArrayList<String> permList, ArrayList<String> nameList) {

}

public static void main(String[] args) {
Scanner scnr = new Scanner(System.in);

}
}

7.11 LAB: All permutations of names
Write a program that lists all ways people can line up for a photo (all permutations of a list of Strings). The program will read a list of one
word names into ArrayList nameList (until -1), and use a recursive method to create and output all possible orderings of those names
separated by a comma, one ordering per line.
When the input is:
Julia Lucas Mia -1
then the output is (must match the below ordering):
Julia, Lucas, Mia
Julia, Mia, Lucas
Lucas, Julia, Mia
Lucas, Mia, Julia
Mia, Julia, Lucas
Mia, Lucas, Julia
