Question

In JAVA

#3 Write a program named nameChanger.java. This program will only have a driver class with a main. This program will have the user enter a series of names(first and last), which will then be stored in a String array. You will then change the values of each of the names in the array, so that they are stored lastname, firstname, and then output the revised array.

import java.util.Scanner;

public class nameChanger {

    public static void main(String[] args) {
        Scanner in = new Scanner(System.in);
        System.out.print("How many names: ");
        String[] names = new String[in.nextInt()];
        in.nextLine();
        for (int i = 0; i < names.length; i++) {
            System.out.print("Enter a name (first and last): ");
            names[i] = in.nextLine();
        }
        for (int i = 0; i < names.length; i++) {
            String[] words = names[i].split(" ");
            names[i] = words[1] + ", " + words[0];
        }
        for (int i = 0; i < names.length; i++) {
            System.out.println(names[i]);
        }
    }
}
