    Without scan.nextLine() not read from your next line.

    if your input is:

    42
3.1415 Welcome to HackerRank's Java tutorials!

    the output is:

    String:  Welcome to HackerRank's Java tutorials!
Double: 3.1415
Int: 42

    So this time the output is correct but the input is not.

    Check the box " Test against custom input" and play yourself.

    Also next code works

    import java.util.Scanner;

public class Solution {

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