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("what is your name?  ");
        //thisIsAnExampleOfCamelCasing
        console.printf("Hello, my name is %s\n", firstName);
        console.printf("%s is learning how to write Java\n", firstName);
  }

Hello,

Do you have Java installed on your machine? If not, this could explain why your receiving that message.

Why are you trying to write Java in an HTML file?

Hi!

Does your file end in .html or .java? If it ends in .html, right click it, click rename, and replace the .html with .java, this will make it a java file instead of a html file

Yes.. check your java file make sure it's "Introductions.java", and when you compile it:

$ javac Introductions.java $ java Introductions

Just like the tuts said.

Good luck.
