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 comprehensive object model in Java
- Program models oriented toward interfaces and abstract classes to ensure greater application flexibility and independence among subsystems
- Utilizing abstract classes to extract common functionality, extended by the flexibility provided by interfaces
The Role of Dynamic and Static Objects in the Application Model
- Static Java classes and the dynamic properties of these classes
- Distinguishing the functionality of static versus dynamic entities within Java, including typical use cases and best practices for designing solutions
- 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 fundamental properties of the String class and an analysis of how String objects are managed by the virtual machine.
The utilization of buffer classes and operations on 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 based on dedicated classes
- Tokenization, searching, and pattern matching for string types
I/O Operations
- In-depth discussion of Java I/O mechanisms, including the Stream, Writer, and Reader classes, as well as wrapper 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 Challenges
- Comprehensive exploration of topics ranging from the thread abstraction mechanism in Java to thread synchronization and grouping, addressing common issues such as deadlocks
Java Reflection – Introduction and Application
- Introduction to the Java reflection mechanism
- Discussion of reflection implementation in Java, including loading and executing class methods, instantiating classes, and inspecting class structures
Java Serialization
- Introduction to Java object serialization
- Concepts of serialization, techniques for serializing objects, handling dependent objects, and strategies to avoid common pitfalls
- Typical applications of serialization, including examples with RMI and CORBA
Requirements
Prior knowledge of the concepts covered in the Java Fundamentals course is required.
