Thread: Java reverse order using pointers

This is what I have to do:
Write a program that takes a string of someone's name and prints it out last name first. Your program must use pointers, not array subscripts. You may use the available string manipulation functions if you find an opportunity.
Example:
"George Washington"
"Washington, George"

I am not sure how to reverse the name, I have been looking in my textbook and online and cannot figure it out. This is what I have put together so far, it does not run. At the end it says unnecessary return value. I have a feeling if my code did run it would be completely wrong. I really appreciate any help given.

import java.util.*;
import java.util.Scanner;
public class Test {
    public static void main ( String [] args )
{
    Scanner sc = new Scanner(System.in);
 
    System.out.print("Enter name: ");
    String name = sc.nextLine();
 
    String lastname = "";
	    String firstname = "";
	    for(int i = 0; i < name.length(); i++)
	    {
	        if(name.charAt(i) == ' ')

You're in the main method, which has a void return type. Just replace the return by a System.out.println(....).
