printf statements generally look like

console.printf("%s some string %d", someVariable, someOtherVariable);

where the values of the variables passed to the function at the end are inserted into the string in place of the format specifiers.

you have one specifier, so you need a corresponding variable with it. the variable you want to print is firstName. the output string needs to look like "Ahmed can code in Java!"

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