Hi Gaurav,

For this specific example the challenge wants you to use the console class which has been imported for you already; 

// I have setup a java.io.Console object for you named console

For this challenge you don't need the Scanner class, however for future reference if you're going to use Scanner like Console you have to import from the java.util package like so; 

import java.util.Scanner; 

public class jar{


  public static  void main(String [] args){

     Scanner sc = new Scanner(System.in);

    //If you would like to use the Scanner class in the future it would some this;
    System.out.print("Oh hey! Welcome to Java! Enter in your name here:  "); 
    String name = sc.nextLine(); 
    System.out.println("Hello " + name + " have a great day!"); 

  }
}

Back to the challenge, the challenge wants you to use the console.printf method and the %s String formatter so if you're able to try this; 

// I have setup a java.io.Console object for you named console
String firstName = "Gaurav";
console.printf("%s can code in Java!", firstName);
