Day 0: Hello, World - HackerRank 30 days of code solution

Objective 

To complete this challenge, you must save a line of input from stdin to a variable, print Hello, World. on a single line, and finally print the value of your variable on a second line.

You've got this!

Note: The instructions are Java-based, but we support submissions in many popular languages. You can switch languages using the drop-down menu above your editor, and the  variable may be written differently depending on the best-practice conventions of your submission language.

Input Format

A single line of text denoting  (the variable whose contents must be printed).

Output Format

Print Hello, World. on the first line, and the contents of  on the second line.

Sample Input

Welcome to 30 Days of Code!

Sample Output

Hello, World. 
Welcome to 30 Days of Code!

Explanation

On the first line, we print the string literal Hello, World.. On the second line, we print the contents of the variable which, for this sample case, happens to be Welcome to 30 Days of Code!. If you do not print the variable's contents to stdout, you will not pass the hidden test case.

Solution :

public class Solution {
public static void main(String[] args) {
        // Create a Scanner object to read input from stdin.
Scanner scan = new Scanner(System.in); 

// Read a full line of input from stdin and save it to our variable, inputString.
String inputString = scan.nextLine(); 

// Close the scanner object, because we've finished reading 
        // all of the input from stdin needed for this challenge.
scan.close(); 
      
// Print a string literal saying "Hello, World." to stdout.
System.out.println("Hello, World.");
        System.out.println(inputString);
      
    // TODO: Write a line of code here that prints the contents of inputString to stdout.
}
}
