Godfrey;

Let's walk through this entire challenge as your particular question comes up quite frequently.

Task 1

Define a string variable named firstName that stores your name. Set the value to your name.

It sounds like you have gotten through this task, but here is the code:

// Course: Java Basics
// Module: Getting Started with Java
// Challenge: Strings, Variables, and Formatting
// Task: 1 of 3

String firstName = "Godfrey";

Task 2

Call the print function on the console object and make it print out "<YOUR NAME> can code in Java!"

Again, it sounds like you got this far as well.

// Course: Java Basics
// Module: Getting Started with Java
// Challenge: Strings, Variables, and Formatting
// Task: 2 of 3

String firstName = "Godfrey";

console.printf("Godfrey can code in Java!");

Task 3

Now replace your name with the firstName variable using the string formatter.

This is where folks seem to be having an issue. In the video he covers the Java string formatter %s in better detail but think of it as a substitution of sorts. When you put the %s in the string Java says "Okay, I'll substitute that with whatever variable the programmer tells me to." In our case we want it to be the firstName string variable. Again, the video shows the syntax of how to do that, but after we close our printf quote we put a comma and then type our variable name. So we would do printf("%s can code in Java!", firstName). That would turn our challenge code into:

// Course: Java Basics
// Module: Getting Started with Java
// Challenge: Strings, Variables, and Formatting
// Task: 3 of 3

String firstName = "Godfrey";

console.printf("%s can code in Java!", firstName);

So now, in this example, when the code runs Java will insert whatever value has been assigned to firstName (Godfrey in this case) in place of the string formatter %s.

I hope that makes some sense.

If you are using an IDE this code will work :)

package com.company;
import java.io.Console;
import java.util.Scanner;

public class Main {
    // Main method
    public static void main(String[] args) {
        Console console = System.console(); // Console object.
        // Welcome to the Introductions program! Your code goes below here.
        Scanner firstNameInput = new Scanner(System.in); // Create a scanner object for input.
        System.out.println("What is your first name?"); // Ask user to enter first name.
        String firstName = firstNameInput.nextLine(); // Receive the user input.
        System.out.println("I'm " + firstName + " and I'm hot"); // Output what is received.
        System.out.println(firstName + " is learning Java."); // Output what is received.
    }
}
