Task #3 Print out to the screen using the printf method on console, "First name: " and the user's first name.

I'm not sure if I understand how to complete task 3. I'd appreciate some help. Thanks.

IO.java 
// I have imported java.io.Console for you.  It is a variable called console.
String firstName = console.readLine("What is your name?"  );
String lastName = console.readLine("What is your last name?"  );
console.printf("%s Craig", firstName);

If I understand correctly the question states you should print " "First name: " and the user's first name." right now though, you are printing "[user's first name and] Craig" so that is why you are getting that error.

Try

console.printf("First name: %s", firstName);

@gloria Thanks for your help. I'm a little confused because I don't understand why we're printing "First Name" to the console.

Would that essentially look like the line below? (Assuming the user entered "Gloria" as their name.

Gloria: What is your name?

The final bit of code looked like this.

// I have imported java.io.Console for you.  It is a variable called console.
String firstName = console.readLine("What is your name?"  );
String lastName = console.readLine("What is your last name?"  );
console.printf("First name: %s", firstName);
console.printf(“Last name: %s”, lastName);

No... it will print...

"what is your name?"

I'll enter : "Gloria" and it will store it in the variable firstName. :)
