Course Outline
Abstract classes
- Principles for declaring and implementing abstract classes
- Common challenges 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 comprehensive object model in Java
- Designing programs using interfaces and abstract classes to enhance application flexibility and ensure independence among subsystems during implementation
- Leveraging abstract classes to extract common functionality, supplemented by the flexibility provided by interfaces
The role of dynamic and static objects in the application model
- Static Java classes and their dynamic characteristics
- Distinguishing between the functionality of static and dynamic entities in Java, including typical use cases and best practices for designing solutions based on these concepts
- Introduction to design patterns
- Overview of the factory design pattern
Operations with simple types and wrapper classes
- Key facts and techniques for extending the use of primitive types within the Java object model
- The role of wrapper classes for primitive types and their common applications
Special Objects in Java: the String, StringBuilder, and StringBuffer classes
Review of the fundamental properties of the String class and an analysis of how String objects are managed by the virtual machine
Utilizing buffer classes for efficient string manipulation
Formatting, parsing, and regular expressions
- Introduction to regular expressions in Java
- Exploration of basic techniques using the String class and advanced methods leveraging dedicated regex classes
- Tokenization, searching, and pattern matching for string data types
I/O operations
- In-depth examination of Java I/O mechanisms, including streaming, Writer and Reader classes, wrapper classes, and buffered streams
- Managing file and socket operations, including opening, closing, and writing
Inner classes - detailed discussion
- Implementation strategies and practical uses of inner classes, including anonymous classes in Java
Threads - detailed discussion, applications, and issues
- Comprehensive coverage of thread abstraction mechanisms in Java, thread synchronization, and grouping threads, with a focus on common concurrency issues such as deadlocks
Java Reflections - Introduction and application
- Overview of the Java reflection mechanism
- Detailed discussion on implementing reflection, loading and executing class methods, instantiating classes, and inspecting class structures
Java Serialization
- Introduction to object serialization in Java
- Understanding what serialization is, how to serialize objects, managing interdependent objects, and avoiding common serialization pitfalls
