I am doing the code exactly as Craig is describing, and it is giving me error messages and not showing me what I typed.

Hi there! I took a look at your code and ran it in workspaces. Unfortunately, it's not exactly like Craig's. There are a couple of lines that are causing errors and one line where I think the output is not what you intended. The first line is on line 8. And it is this:

Introductions.java:8: error: incompatible types: String cannot be converted to boolean           
  String firstName = console.readline("What is your name?  ");   

You wrote:

String firstName = console.readline("What is your name?  ");

But there is a capitalization error on readline. You meant to write:

String firstName = console.readLine("What is your name?  ");  // note the upper case "L" here

Once I save the file, compile, and run it again, I get a new error (a little scarier) this time on line 10:

Exception in thread "main" java.util.MissingFormatArgumentException: Format specifier '%s'       
        at java.util.Formatter.format(Formatter.java:2519)                                       
        at java.util.Formatter.format(Formatter.java:2455)                                       
        at java.io.Console.format(Console.java:170)                                              
        at java.io.Console.printf(Console.java:209)                                              
        at Introductions.main(Introductions.java:10)

I know that looks scary but here's what it's trying to tell us. You specified in your string the %s token to tell it to format the string using a variable name. But from Java's perspective, you never told it which variable to use. This is because you misplaced your ending quotation mark.

You wrote:

console.printf("Hello, my name is %s\n, firstName");

But you meant to write:

console.printf("Hello, my name is %s\n", firstName); // note that I moved the quotation mark before the comma

The last problem won't actually produce an error, but I believe the result is unintended. Regardless of what was typed in, the string "Sam is learning how to write java" and a new line character. But if I entered "Charlie", I'd likely want it to print out "Charlie is learning how to write java", right?

So where you wrote:

console.printf("Sam is learning how to write java\n", firstName);

I believe you meant to write:

console.printf("%s is learning how to write java\n", firstName);  // note that I replaced Sam with %s

I suggest you look at Craig's full code at 2:11 of this video.

Hang in there! You're doing great! These small details take a good deal of practice to spot. If you weren't detail-oriented before, you will be. But the first part of learning anything is knowing how to ask the question, which you did brilliantly! We got a ton of helpful information from you, so thank you for that.

Hope this helps!
