Scanner is a class in Java that is used to read input in a Java program. To understand what a class in Java (or any other programming language), read the following link.

https://www.geeksforgeeks.org/classes-objects-java/


Let's say you are writing a Java program for adding two numbers. You would write the program in such a way that first it prompts the user two input two numbers, reads what the user has typed on the screen and then prints out the result of adding the two numbers.


An example program is as follows:

import java.util.Scanner; 
public class AddTwoNumbers 
{ 
    public static void main(String[] args)
    {
         // instantiate a scanner object that will be used 
         // to read input from the command line
         Scanner sc = new Scanner(System.in);

         int number1 = sc.nextInt();
         int number2 = sc.nextInt();
         int sum = number1 + number2;

         System.out.println("Sum: "+sum);
    }
}
