The compiler can't read the String variable "s" in this code:

public class Solution {

public static void main(String[] args) {
    Scanner scan = new Scanner(System.in);
    int i = scan.nextInt();
    scan.nextLine();
    System.out.println("String: " + s);
    double d = scan.nextDouble();
    scan.nextLine();
    System.out.println("Double: " + d);
    String s = scan.nextLine();
    System.out.println("Int: " + i);

    // Write your code here.




}

}
