Unexpected line printing when using Scanner

Question

I am using practice it for java, and have a question about the following exercise:

Write a complete program called "TheNameGame," where the user inputs a first and last name and a song in the following format is printed about their first, then last, name. Use a method to avoid redundancy.

What is your name? Fifty Cent
Fifty Fifty, bo-Bifty
Banana-fana fo-Fifty
Fee-fi-mo-Mifty
FIFTY!
Cent Cent, bo-Bent
Banana-fana fo-Fent
Fee-fi-mo-Ment
CENT!

This is the code I wrote for the answer:

public class TheNameGame {
    public static void main(String[] args) {
        Scanner scan = new Scanner(System.in);
        String first = scan.next();
        String last = scan.next();
        String newFirst = first.substring(1);
        String newLast = last.substring(1);

        System.out.println("What is your name? " + first + " " + last);
        playGame(first, newFirst);
        playGame(last, newLast);
    }
}

public static void playGame(String name, String nn) {
    System.out.println(name + " " + name + ", " + "bo-B" + nn);
    System.out.println("Banana-fana fo-F" + nn);
    System.out.println("Fee-fi-mo-M" + nn);
    System.out.println(name.toUpperCase() + "!");
}

And this is the output:

Fifty Cent
What is your name? Fifty Cent
Fifty Fifty, bo-Bifty
Banana-fana fo-Fifty
Fee-fi-mo-Mifty
FIFTY!
Cent Cent, bo-Bent
Banana-fana fo-Fent
Fee-fi-mo-Ment
CENT!

My question is; where is the first line (Fifty Cent) coming from? Thank you in advance.

Answer 1

I see that you are trying to ask the question, and then get the input. You only have to make a couple of minor changes in your main method. Your main method should look like this:

public static void main(String[] args) {
    Scanner scan = new Scanner(System.in);
    System.out.print("What is your name? "); //asks question first,
    String first = scan.next();              //THEN accepts first
    String last = scan.next();               //and last name
    String newFirst = first.substring(1);
    String newLast = last.substring(1);

    playGame(first, newFirst);
    playGame(last, newLast);
}

This will give the output:

What is your name? Fifty Cent
Fifty Fifty, bo-Bifty
Banana-fana fo-Fifty
Fee-fi-mo-Mifty
FIFTY!
Cent Cent, bo-Bent
Banana-fana fo-Fent
Fee-fi-mo-Ment
CENT!

It first asks the question, then accepts the first and last name of the user. Your issue was simply that your code was out of order.

Answer 2

My question is; where is the first line (Fifty Cent) coming from?

When you enter :

Fifty Cent

String first = scan.next(); will read Fifty and String last = scan.next(); read Cent

for that when you print :

System.out.println("What is your name? " + first + " " + last);

It will print :

What is your name? Fifty Cent

Answer 3

My question is; where is the first line (Fifty Cent) coming from?

It is not coming from anywhere. You input it, when you do

String first = scan.next();
String last = scan.next();

and Fifty Cents stays there on the screen. Remember , values you input continue to stay on the screen .
