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 Java object-oriented abstraction
- The comprehensive object model in Java
- Programmatic models leveraging interfaces and abstract classes to enhance flexibility and ensure independence among subsystems during implementation
- Utilizing abstract classes to extract shared functionality while extending the flexibility provided by interfaces
The Role of Static and Dynamic Objects in the Application Model
- Static Java classes and their dynamic characteristics
- Distinguishing between the functionalities 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
- Introduction to the Factory design pattern
Operations with Primitive Types and Wrapper Classes
- Key facts and techniques to expand the utility 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: The String Class, StringBuilder, and StringBuffer
A review of the fundamental properties of the String class and an examination of how the Java Virtual Machine handles String objects.
Utilisation of buffer classes and operations involving strings.
Formatting, Parsing, and Regular Expressions
- Introduction to regular expressions in Java
- Discussion of both basic techniques for handling regular expressions (using the String class) and advanced techniques utilizing dedicated classes for this purpose
- Tokenization, searching, and pattern matching for string types
I/O Operations
- A detailed discussion of Java I/O mechanisms, including streaming classes, Writer and Reader classes, and wrapper and buffering classes for Java streams
- Opening, closing, and writing to files and sockets
Inner Classes – Detailed Discussion
- An explanation of how to implement and utilize inner classes in Java, as well as anonymous classes
Topics – Detailed Discussion, Applications, and Problems
- Discussion of subject matter ranging from the thread abstraction mechanism in Java to thread synchronization and connecting threads within a group. This includes presenting and discussing common issues related to thread execution, such as deadlocks
Java Reflection – Introduction and Application
- Introduction to the Java reflection mechanism
- Topics covered include the implementation of reflection in Java, loading and executing class methods, instantiating classes, and inspecting class structures
Java Serialization
- Introduction to Java object serialization
- Explanation of what serialization is, how to serialize objects, handling objects that depend on one another, and strategies to avoid common problems associated with these issues
- Typical use cases, with examples of serialization in RMI and CORBA
Requirements
Participants must possess knowledge of the topics covered in the Java Fundamentals course.
