Course Outline
Abstract Classes
- Principles of declaration and implementation of 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 complete object model in Java
- An application-oriented program model that utilizes interfaces, abstract classes, and concrete classes to provide greater flexibility and independence among subsystems
- Using abstract classes to extract common functionality, extended by the flexibility offered through interfaces
The Role of Dynamic and Static Objects in the Application Model
- Static Java classes and their dynamic properties
- Distinguishing the functionalities of static and dynamic entities in Java, including typical uses and best practices in solution design
- Introduction to design patterns
- Introduction to the factory design pattern
Operations with Simple Types and Wrapper Classes
- Essential facts and techniques for extending the use of simple types within the Java object model
- The role of wrapper classes for simple types and their typical applications
Special Java Objects: String, StringBuilder, and StringBuffer
Review of the basic properties of the String class and an analysis of how the virtual machine handles String objects
The use of buffer classes for manipulating character sequences
Formatting, Parsing, and Regular Expressions
- Introduction to regular expressions in Java
- Basic techniques for handling regular expressions (using the String class) and advanced techniques using dedicated classes
- Tokenization, search, and pattern matching for string types
I/O Operations
- A detailed discussion of Java I/O mechanisms, including streams, Writer and Reader classes, wrappers, and buffered streams
- Opening, closing, and writing to files and sockets
Inner Classes - Detailed Discussion
- Implementation and usage of inner classes in Java, including anonymous classes
Threads - Detailed Discussion, Applications, and Problems
- Thread abstraction mechanisms in Java, synchronization, and thread groups, with a focus on common issues such as deadlocks
Java Reflection - Introduction and Application
- Introduction to the Java reflection mechanism
- Implementation of reflection in Java, including loading and executing methods, instantiating classes, and inspecting class structures
Java Serialization
- Introduction to Java object serialization
- Understanding serialization, methods for serializing objects, handling interdependent objects, and avoiding common pitfalls
