They want you to make use of the variable you created, instead of literally writing your name again. And with the printf method theres a nice way of doing this:

console.printf("Hello, my name is %s", firstName);

In the code above %s will be replaced with the value stored in firstName. The s stands for String.

Without using the printf method. printing the same thing out would be:

console.print("Hello, my name is " +  firstName);

This achieves the same result, but its better to get used to printf as this will be much more useful in the future when you need to print formatted strings.
