Learning Java from 0 to Senior 8/100: File Handling in Java

File Handling in Java — Managing Data with Precision

Introduction to File Handling

In any application, data persistence is crucial. Java provides robust support for file I/O operations allowing the reading from and writing to files seamlessly. This capability is fundamental for storing data like application logs, user data, configurations, and more.

Core Concepts in File Handling

1. File Class: The java.io.File class is an abstract representation of file and directory pathnames. It provides methods for creating, reading, and modifying files and directories.
2. FileInputStream and FileOutputStream: These classes are used for reading from and writing to files, respectively.
3. BufferedReader and BufferedWriter: These provide buffering to your read and write operations, improving I/O performance.
4. FileReader and FileWriter: These are convenience classes for reading and writing text files.
