How to Use Scanner to Read Names from Keyboard in Java | Java IO | Java Tutorial
Welcome to our Java tutorial on reading names from the keyboard using the `Scanner` class in Java!
In this video, you'll learn how to use the `Scanner` class to interactively read and process names or strings entered by the user from the keyboard in a Java program.
**Overview**:
The `Scanner` class in Java provides powerful input-parsing capabilities, allowing you to capture and manipulate user-entered data efficiently. By associating a `Scanner` object with the standard input (`System.in`), you can prompt users to enter names or strings interactively.
**Key Concepts**:
We'll demonstrate how to create a `Scanner` object for reading input from the keyboard (`System.in`).
Use `Scanner` methods such as `nextLine()` to read entire lines of text (including names) entered by the user.
Handle input validation and error checking to ensure robust string input handling.
**Java Code Examples**:
Through practical code examples, you'll learn how to:
Initialize a `Scanner` object with the standard input stream (`System.in`).
Prompt users to enter names or strings and capture them using `Scanner` methods.
Implement basic input validation techniques to handle unexpected input gracefully.
**Why Use Scanner for Keyboard Input?**:
`Scanner` simplifies the process of capturing and processing user input, making it easy to handle textual data (such as names) 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 names or strings from the keyboard in your Java programs, empowering you to create interactive applications that process user input effectively.
