    The Scanner class in Java, found in the java.util package, is used to read input from various sources like the console, files, or strings. It supports reading different data types such as String, int, double, etc., making it a versatile tool for user input handling.

    Example: Reading multiple types of input

    import java.util.Scanner;

    public class Main {
    public static void main(String[] args) {
    Scanner sc = new Scanner(System.in); // Create Scanner object

    System.out.print("Enter your name: ");
    String name = sc.nextLine(); // Read String

    System.out.print("Enter your age: ");
    int age = sc.nextInt(); // Read int

    System.out.print("Enter your salary: ");
    double salary = sc.nextDouble(); // Read double

    System.out.println("Name: " + name);
    System.out.println("Age: " + age);
    System.out.println("Salary: " + salary);

    sc.close(); // Close scanner to avoid resource leaks
    }
    }
