import java.util.Scanner;

public class Solution {

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

This is the code.
What changes should i make to the code inorder to accept a string with blank spaces as input and print it ?

What I have tried:

Input (stdin):
42
3.1415
Good Morning have a nice day!

My Output (stdout):
String:
Double: 3.1415
Int: 42

Expected Output:
String:Good Morning have a nice day!
Double: 3.1415
Int: 42

Ok. This is going to be a Question and Answer type. I found the answer for my question just now.

I have placed the nextLine method just after the nextInt/nextDouble method.

I forgot the fact that nextInt method wouldn't read the "/n" newline character that is given through stdin by user.

So before placing the nextLine method, a blank scan.nextLinemethod would read through the "/n" newline character.

Corrected code looks like this:

C#

scan.nextLine();
String s;
s = scan.nextLine();
