I dont get any output, i wanted to get a name from the user then print thanks + name.

My code:

import java.io.Console;

public class Introductions {

public static void main(String[] args) {
    Console console = System.console();
    // Welcome to the Introductions program!  Your code goes below here
    String firstName = console.readLine("Tell me your name. \n);
                                        console.printf("Thank you %s! \n");

} }

Hi Kevin, the printf method takes two arguments. You have forgotten to supply the second argument, which tells printf to use the value of the variable firstname where the string placeholder (%s) is. Try this:

console.printf("Thank you %s! \n", firstName);

Without firstName supplied to printf, it doesn't have anything to use where the %s placeholder is.
