00 Day : Hello, World.

Ohayo!

I want to give myself an opportunity to practice mastery …so I set myself a small challenge to learn one programming concept &/or framework a day and C-O-D-E it.

I am using Java and Today’s concept is as follows

…save a line of input (using stdin) to a variable

…print 1st line “Hello, World.”

…print 2nd line <variable>

Code :

import java.io.*;
import java.util.*;
import java.text.*;
import java.math.*;
import java.util.regex.*;
public class Solution {
   public static void main(String[] args) {
      Scanner scan = new Scanner(System.in); // use the Scanner class to read from stdin
      String inputString = scan.nextLine(); // read a line of input and save it to a variable
      scan.close(); // close the scanner
 
      // Your first line of output goes here
      System.out.println(“Hello, World.”);

      // Write the second line of output
      System.out.println(inputString);
   }
}

Input :

Ohayo!

Output :

Hello, World.
Ohayo!
