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


  String firstName = "Phuc";

    console.printf("%s can code in java!" firstName);

the question was: " Now replace <YOUR NAME> in the console.printf expression with the firstName variable using the string formatter."

Your answer is almost correct. Your console.printf should pass the value of the firstName variable into the string by replacing the %s placeholder. There is one small syntax error causing you to not pass. You must put a comma between the string and the variable you are passing to it.

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