Mastering Java: Understanding Java I/O (Input/Output)

Master Java

Welcome back to our Java series! In the previous article, we explored the Java Collections Framework. Now, let’s dive into Java’s Input/Output (I/O) operations, which are essential for reading from and writing to data streams.

Java I/O is a fundamental aspect of Java programming. It enables you to interact with data in various forms, such as files, console input, and network connections.

1. Java I/O Streams

Java uses streams to perform input and output operations. A stream is a sequence of data. There are two types of streams:

• Byte Streams: Used to handle raw binary data.
• Character Streams: Used to handle character data.

Byte Streams:

• InputStream: Abstract class representing an input stream of bytes.
• OutputStream: Abstract class representing an output stream of bytes.

Character Streams:

• Reader: Abstract class representing a character stream.
• Writer: Abstract class representing a character output stream.

2. Reading and Writing Files
