Here is the challenge solution:

// Task 1: Define a string variable named firstName that stores your name. 
// Set the value to your name.
String firstName = "mark";

// Task 2: Call the printf method on the console object and make it write out
// "<YOUR NAME> can code in Java!"
console.printf("mark can code in Java!\n");

// Task 3
// Now replace <YOUR NAME> in the console.printf expression with the firstName
// variable using the string formatter.
console.printf("%s can code in Java!\n", firstName);

Edit: fix comments

Hi,

You need to answer the challenge questions.

  1. Define a string variable named firstName that stores your name. Set the value to your name. 
// I have setup a java.io.Console object for you named console
String firstName = "Mayk";
  1. Call the printf method on the console object and make it write out ** "YOUR NAME can code in Java!"**
// I have setup a java.io.Console object for you named console
String firstName = "Mayk";
console.printf("Mayk can code in Java!");
  1. Now replace YOUR NAME in the console.printf expression with the firstName variable using the string formatter.
// I have setup a java.io.Console object for you named console
String firstName = "Mayk";
console.printf("%s can code in Java!", firstName);
