How to Use Scanner to Read Numbers from Keyboard in Java | Java IO | Java Tutorial

Welcome to our Java tutorial on reading numbers from the keyboard using the `Scanner` class in Java!

In this video, you'll learn how to use the `Scanner` class to interactively read numeric input from the keyboard in Java, enabling you to create programs that accept and process user-entered numbers.

**Overview**:

**Key Concepts**:
- Use `Scanner` methods such as `nextInt()` and `nextDouble()` to read integers and floating-point numbers entered by the user.
- Handle exceptions and input validation to ensure robust numeric input handling.

**Java Code Examples**:
Through practical code examples, you'll learn how to:
- Prompt users to enter numeric values and capture them using `Scanner` methods.
- Implement error handling and validation techniques to handle unexpected input gracefully.

**Why Use Scanner for Keyboard Input?**:
- `Scanner` simplifies the process of reading and parsing user input, making it easy to handle different types of data (such as numbers) entered via the keyboard.
- It provides a user-friendly way to interact with Java programs, enabling dynamic input and response mechanisms.

By the end of this tutorial, you'll have a solid understanding of how to leverage the `Scanner` class to read numbers from the keyboard in your Java programs, empowering you to create interactive applications that process user input effectively.
