YouTube Excerpt: Scanner Class in Java | Java Tutorials | Not A Coder @NotACoder1999 In Java programming, the Scanner class is a utility class that provides a simple way to read input data from various sources, including the keyboard and files. It is part of the java.util package and is commonly used for reading user input from the console. To use the Scanner class in Java, you must first import it into your program using the following statement: java import java.util.Scanner; Once you have imported the Scanner class, you can create a new Scanner object and use its methods to read input data. The following example demonstrates how to read a string and an integer from the console using the Scanner class: java import java.util.Scanner; public class ScannerExample { public static void main(String[] args) { Scanner scanner = new Scanner(System.in); // create new Scanner object System.out.print("Enter your name: "); String name = scanner.nextLine(); // read a string System.out.print("Enter your age: "); int age = scanner.nextInt(); // read an integer System.out.println("Hello, " + name + "! You are " + age + " years old."); } } In this example, we first create a new Scanner object scanner by passing the System.in parameter to the constructor, which specifies that we want to read input from the keyboard. We then use the nextLine() method to read a line of text entered by the user and store it in the name variable. Similarly, we use the nextInt() method to read an integer entered by the user and store it in the age variable. Finally, we print out a message that includes the user's name and age using string concatenation. Note that we use the println() method instead of print() to print the message on a new line. In addition to reading input from the console, the Scanner class can also be used to read input from files or other input sources. To do this, you simply need to pass the appropriate input source as a parameter to the Scanner constructor.
