CMP 175 Java Unit 6.2 & 6.3 | I/O Class Hierarchy and File Stream Manipulation Explained

In this video, we cover CMP 175 (Object Oriented Programming - Java), Topic 6.2 & 6.3: I/O class hierarchy and file manipulation using streams. Understand Java I/O class hierarchy with InputStream, OutputStream, Reader, and Writer families Learn file handling with FileInputStream and FileOutputStream for byte-based operations Work with DataInputStream and DataOutputStream to read and write primitive data types safely Explore ObjectInputStream and ObjectOutputStream for object serialization and deserialization Compare when to use byte streams vs higher-level wrapped streams for practical programs Build a clear foundation for implementing real Java file processing tasks in labs and projects This topic is important for upcoming OOP concepts, especially practical application development and persistent data handling.
