Hi Ary,

try this:

// I have setup a java.io.Console object for you named console
String firstName ="Ary";
console.printf("My name is %s ", firstName);

The expression %s helps you to put a String (that you stored inside the "firstName" variable) in your text. Afterward you can change "Ary" to whatever you want. But you don´t need to change your variable "firstName" inside the parenthesis of the printf statement.

To use this cool function you need a proper syntax. And it is:

console.prinf("Your text %s ", yourVariable);
// console is a name of the Console class that Craig have setup for us before
//the %s will be replaced with a String of your choice
//or you can use more of them
String firstName = "Ary";
String middleName = "de";
String lastName = "Oliveira";
console.printf("I am %s  %s  %s ", firstName, middleName, lastName);

Let me know if you need mor help
