Java Java Basics Getting Started with Java Strings, Variables, and Formatting

How can I replace < MY NAME> in the console.printf expression with the firstName variable using the string formatter?

Maybe I didn't quite understand this question. Does this mean just changing your name in the quoted text at the Variable String firstName?

please help.

From a frustrated Beginner...

Hi there,

Try something like this ... 

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

Hope that helps.

Steve.

Hey Francis,

can you see the difference between challenge 2 and 3?

// I have setup a java.io.Console object for you named console

//Challenge Task 1 of 3
String firstName = "Francis";

//Challenge Task 2 of 3
console.printf(firstName + " can code in Java"); 

//change the code frome challenge 2 into code below

//Challenge Task 3 of 3 after replacing <YOUR NAME> 
console.printf("%s can code in Java ", firstName);
//replace your name with %s = String formatter and put firstName aftrer "",

I hope it helps

Let us know if you need help
