Hello on setting up variable

I just need to find out why my code isnt't working right.

Name.java 
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 = "Roberto";
      console.printf("hello, my name is /n", firstname);
  }
}

Roberto, you did way too much work. They didn't want a program!

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

Note, Java is case-sensitive, so firstname and firstName are different. "%s" is a format specifier, and will be replaced by the value of the firstName variable when the String is printed.

You had the wrong symbol: the \n is a new line character and the %s is basically a placeholder for a variable. It should look like this:

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 = "Roberto";
      console.printf("hello, my name is %s", firstName);
  }
}
