Scanner Class in Java:
==> Scanner is a class in java.util package used for obtaining the input of the primitive types like int, double,and strings.
==> Using the Scanner class in Java is the easiest way to read input in a Java program, though not very efficient if you want an input method for scenarios where time is a constraint like in competitive programming.
Example program:
package javaprogram; import java.util.Scanner; // Import Scanner class public class ScannerClass { public static void main(String[] args) { Scanner scanner = new Scanner(System.in); // Taking String input System.out.print("Enter your name: "); String name = scanner.nextLine(); // Taking integer input System.out.print("Enter your age: "); int age = scanner.nextInt(); // Displaying input values System.out.println("Hello, " + name + "! You are " + age + " years old."); } } Output:
