how to take user input in Java : Scanner class

In this tutorial, we guided you through How to take input in Java by importing the Scanner class
-------
Java is a popular, high-level programming language, It is an object-oriented language, which means that it is based on the concept of objects, which have properties and methods, and is designed to be platform-independent, so that code written in Java can run on any device that has a Java Virtual Machine (JVM) installed.
-------
Java is widely used for developing a wide range of applications, such as:
Desktop applications, Web applications, Mobile applications, Embedded systems, home devices, industrial control systems, and Enterprise applications, Java is also used for developing server-side technologies such as Servlets, JavaServer Pages (JSP), and JavaServer Faces (JSF).
----------
Java is known for its "write once, run anywhere" (WORA) philosophy

Brief Guide: How to take user input in Java?
Step 1 -In Java, the Scanner class can be used to read input from the user. To use the Scanner class, you need to first import it by adding the following line at the top of your code:
import java.util.Scanner;
Step 2- Then you can create a new Scanner object and use its methods to read input from the user. For example, to read an Integer from the user, you can use the nextInt() method:
Scanner reader = new Scanner(System.in);
System.out.print("Enter a Number: ");
int variable = reader.nextInt();
** You can also use methods like nextLine() or nextDouble() to read String input, and nextBoolean() to read a boolean value.

Step 3- Once you are done using the scanner, it is a good practice to close the scanner object,
scanner.close();
Step 4- It's important to note that when you close the Scanner object, the underlying InputStream object, in this case System.in, is also closed, so you cannot read any more input from it.
