Introduction

File handling is a crucial aspect of many Java applications, whether you’re developing simple command-line tools or complex enterprise systems. Java 8 offers a variety of methods to read and write files, each suited to different use cases. From traditional approaches using FileInputStream and FileReader to modern techniques leveraging lambda expressions and the java.nio.file package, Java 8 provides developers with powerful tools for efficient file processing.

In this short tutorial, we’ll explore multiple methods to read and write files in Java 8. You’ll learn how to read text files using BufferedReader, take advantage of the Files class introduced in Java 7, and simplify your code with lambda expressions. On the writing side, we’ll cover the use of FileOutputStream, FileWriter, and PrintWriter to help you choose the right approach for your needs. By the end of this tutorial, you’ll have a solid understanding of file handling in Java 8 and be equipped to handle files efficiently in your applications.
