Call the print f method

Hey! I'm currently taking the Java Basics course and one of the exercises asks the following: //Call the printf method on the console object and make it write out "<YOUR NAME> can code in Java!" The error I'm getting is: Bummer: There is a compiler error. Please click on preview to view your syntax errors! // I have setup a java.io.Console object for you named console //Console console = System.console(); import java.util.*; String firstName = "Mada"; console.printf("%s, firstName can code in JAVA!");

Any ideas what it's expecting me to do? I tried without the Console console... and without importing the java.util.*

Hi, the way you wrote the printf method, firstName is part of the string. What you should do is use firstName outside of the quotation marks. For example

String name = "Mada"; console.printf("Hello, my name is %s", name);

You got it wrong. The way you use it is like this: ā€œ%placeholder can code in JAVA!ā€, variableName I placed placeholder because after the ā€œ%ā€ sign you can use s for String, d for digit and f for floating number. Hope I helped
