Java IO API

Java I/O is a set of classes that give access to external resources including file systems and the network.

This tutorial will guide you through the Java I/O API, presenting the basic notions you need to understand in order to start writing Java code that takes advantage of the API.

1. Understanding the Main Java IO Concepts

   Introducing the Java I/O API: files, paths, streams of characters and streams of bytes.

2. File System Basics

   Working with the file system: working with files and paths, working with directories, getting file metadata.

3. File Operations Basics

   Writing and reading files: getting to know the difference between text files and binary files.

4. Putting it All Together
