Java Byte Streams Explained: FileInputStream & Binary Files | Java Mastery Series

#Java #ByteStreams #FileInputStream Master Java Byte Streams! In this tutorial, we explore the raw foundation of Java I/O: reading and writing pure 8-bit binary data byte-by-byte. We start with a clear introduction to Byte Streams and look at the foundation classes: FileInputStream and FileOutputStream. Because reading raw bytes from a hard drive one-by-one is notoriously slow, we immediately look at how to fix that performance bottleneck using BufferedInputStream and BufferedOutputStream. Next, we unlock the ability to save Java primitive data types directly into a file (like int, double, or boolean) using DataInputStream and DataOutputStream. Finally, we put all this theory to the test with a real-world scenario: writing the logic to read and parse custom Binary File Formats (like image headers or compiled data).
