Raslan,

The problem here is "readline" without the upper case L is not considered as a method for the compiler.

Please change: String firstName = console.readline("what is your name? ");

To: String firstName = console.readLine("what is your name? ");

It will work.

I already tested the code as:

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? "); console.printf("hello, my name is %s\n", firstName); console.printf("%s is learning how to java\n", firstName); } }

And it worked.

Hope this will help you, Amir
