What is Reader class in Java? | Java IO | Java Tutorial

Welcome to our Java tutorial on the `Reader` class in Java I/O!

In this video, you'll learn all about the `Reader` class in Java and how it can be used for reading character-based input streams efficiently.

**Overview**:
The `Reader` class is an abstract class in Java that serves as the superclass for all classes representing character input streams. It is part of the Java IO API and provides methods for reading characters from various input sources, such as files, network connections, or other character-based streams.

**Key Features**:
- `Reader` provides a common set of methods for reading characters, handling input streams, and managing character-based input operations.
- Subclasses of `Reader`, such as `BufferedReader`, `FileReader`, and `InputStreamReader`, implement specific functionalities for reading characters efficiently from different sources.

**Why Use Reader Class?**:
- `Reader` simplifies the process of reading character-based input streams by providing a uniform interface and common methods for reading characters.
- It supports internationalization and character encoding, allowing you to read characters from input sources in different character sets and handle text data effectively.

**Java Code Examples**:
We'll demonstrate how to create and use `Reader` objects, as well as its subclasses, to read character-based input streams from files and other sources. You'll learn how to:
- Initialize `Reader` objects with different input sources, such as files or `InputStream` instances.
- Use `Reader` methods like `read()`, `skip()`, and `close()` to read characters from the input stream and manage input operations.

By the end of this tutorial, you'll have a solid understanding of the `Reader` class and its role in Java I/O operations, empowering you to efficiently read character-based input streams in your Java programs.

I don't understand the thumbs-down, really. Of course, we mention at the beginning that for character data, Reader and Writer are preferred over subclasses of InputStream and OutputStream for character data, then all the examples for InputStream and OutputStream use character data for illustration anyway. However, that is what I see in MOST tutorials around, probably because it is easy for human viewers to look at a text file and understand what they are seeing...
