Scanner class is a predefined class in java which is present in java.util package. It means we have to import this package to use Scanner class in Program. Here we will learn how to use Scanner class and different methods of Scanner class.
Here I would like to start directly with an example which would so helpful to you to understand Scanner class.
// Import the Scanner class
import java.util.Scanner;
class ScannerExample {
public static void main(String[] args) {
// Creating object of Scanner class
Scanner obj = new Scanner(System.in);
System.out.println("Enter First Number");
int num1= obj.nextInt(); // Reading user input
System.out.println("Enter Second Number");
int num2= obj.nextInt(); // Reading user input
System.out.println("Sum is: " + (num1+num2));
}
}
