How to Use Scanner to Receive Command Line Input

Scanner is a simple and easy-to-use utility provided by Java.

import java.util.Scanner;

public class ScannerDemo
   public static void main(String args[])
      Scanner scanner = new Scanner(System.in); //Initializing the Scanner with the Standard input
      System.out.println("Please enter a number: ");
      int intValue = scanner.nextInt(); // Likely to throw java.util.InputMismatchException when incorrect inputs are provided. 
                                // There are similar methods to support other data types
      System.out.println("The number entered is " + intValue);
