The printf method

What does the question mean when it says call the printf method. I think I'm misunderstand the question though knowing the answer?

Name.java 
// I have setup a java.io.Console object for you named console
  String yourName = "Stevano";
  String firstName = "Pamela";
//thisIsAnExampleOfCamelCasing
  console.printf("Hello, my name is %s\n", yourName);
  console.printf("%s is learning how to write java\n", yourName);

When you call a method, you use the dot notation. So in the above code, you're calling printf("hello...) on console whenever you type out: 

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

Think of the dot as a phone call to console, saying you want console to use it's printf method with the associated argument in brackets.
