Summary - Java I/O Streams

Overview of Java I/O Streams

What are I/O Streams?

I/O (Input/Output) streams enable Java programs to read from and write to various data sources like files and network connections. They standardize data handling, making it easier to interact with external sources.

Types of Streams:

Byte Streams: Handle raw binary data (InputStream, OutputStream).

Character Streams: Handle character data (Reader, Writer).

Key Classes:

InputStream/OutputStream: Work with byte data. Examples include FileInputStream, FileOutputStream.

Reader/Writer: Work with character data. Examples include FileReader, FileWriter.

Exploring Java InputStream

InputStream: Reads raw byte data. Common subclasses: FileInputStream, BufferedInputStream.

Exploring Java OutputStream

OutputStream: Writes byte data. Common subclasses: FileOutputStream, BufferedOutputStream.

Exploring Java Reader

Reader: Reads character data. Common subclasses: FileReader, BufferedReader.

Exploring Java Writer

Writer: Writes character data. Common subclasses: FileWriter, BufferedWriter.

Closeable Interface and Try-with-Resources

Closeable Interface: Ensures proper closing of resources like streams.

Try-with-Resources: Automatically closes resources declared within the try statement.

File Handling Essentials

File: Represents files or directories, providing methods to manipulate them.

Path and Files: Used to locate and manage files and directories effectively.
