What is the BufferedWriter in Java? | Java BufferedWriter Class Explained | Java IO | Java Tutorial

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

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

**Overview**:
The `BufferedWriter` class is used to write text to a character-output stream, buffering characters to provide efficient writing of characters, arrays, and strings. It is part of the Java IO API and offers improved performance by reducing the number of I/O operations.

**Key Features**:
- `BufferedWriter` provides buffering capabilities, allowing you to write characters, arrays, and strings to an output stream with improved efficiency.
- It simplifies the process of writing text data to output sources, such as files, network connections, or other character-based streams.

**Why Use BufferedWriter Class?**:
- `BufferedWriter` enhances performance by reducing disk access and improving data transmission efficiency.
- It supports character encoding, enabling you to write text data in different character sets and handle text output effectively.

**Java Code Examples**:
We'll demonstrate how to create and use `BufferedWriter` objects to write text data to output streams, such as files or `OutputStream` instances. You'll learn how to:
- Initialize `BufferedWriter` objects with different output sources.
- Use `BufferedWriter` methods like `write()`, `newLine()`, and `flush()` to write characters, arrays, and strings to the output stream.

By the end of this tutorial, you'll have a solid understanding of the `BufferedWriter` class and its role in Java I/O operations, empowering you to efficiently write text data to output streams in your Java programs.

Very particular, but I think the second line won't contain a terminating newline. I have worked in environments where files missing a terminating newline on the last line would be considered possibly corrupt. That may be less common these days.
