Course Outline
Abstract classes
- Principles for declaring and implementing abstract classes
- Common issues encountered when working with abstract classes
The role of classes, abstract classes, and interfaces in the application model
- Levels of object-oriented abstraction in Java
- The complete object model in Java
- Programmatic approach to interfaces and abstract classes, providing greater flexibility and decoupling between subsystems in their implementation
- Utilizing abstract classes to extract common functionality while extending the flexibility offered by interfaces
The role of static and dynamic objects in the application model
- Static Java classes and their dynamic characteristics
- Distinguishing functionality between static and dynamic entities in Java, including typical use cases and best practices in designing solutions based on static and dynamic constructs
- Introduction to design patterns
- Introduction to the Factory design pattern
Operations with primitive types and wrapper classes
- Key facts and techniques for extending the use of primitive types within the Java object model.
- Discussion on the role of wrapper classes for primitive types and their typical application scenarios
Special Java Objects: String, StringBuilder, and StringBuffer
Review of the String class's basic properties and an analysis of how the JVM handles String objects
Usage of buffer classes and operations on character chains
Formatting, Parsing, and Regular Expressions
- Introduction to regular expressions in Java
- Discussion of both basic techniques for handling regular expressions (via the String class) and advanced techniques using dedicated classes
- Tokenization, searching, and pattern matching for string types
I/O Operations
- A detailed examination of Java I/O mechanisms, including streaming classes, Writer and Reader classes, and stream wrapping and buffering techniques.
- Opening, closing, and writing to files and sockets
Inner Classes: Detailed Discussion
- Exploration of how to implement and use inner classes in Java, including anonymous classes
Topics: Detailed Discussion, Applications, and Problems
- Discussion on topics ranging from the abstraction mechanism of threads in Java to thread synchronization and grouping. The course also addresses common thread-related problems, such as deadlocks
Java Reflection: Introduction and Application
- Introduction to the Java reflection mechanism
- Topics include implementing reflection in Java, loading and executing class methods, instantiating classes, and inspecting class structures
Java Serialization
- Introduction to Java object serialization
- Understanding serialization, how to serialize objects, handling interdependent objects, and avoiding common pitfalls associated with these issues
- Typical use cases, including examples of serialization with RMI and CORBA
Requirements
Knowledge of the topics covered in the Java Fundamentals course.
