Input/Output Streams in Java

This lecture covers the concept of input/output streams in Java, focusing on the classes and methods used for handling byte streams. Starting with an overview of the hierarchy of stream classes, the instructor explains how to write bytes to an output stream, read bytes from an input stream, and close the stream. The lecture also includes practical examples of writing and reading bytes to and from files, demonstrating the use of classes like OutputStream, FileInputStream, and FileOutputStream.
