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 Java object-oriented abstraction
- The comprehensive object model in Java
- Object-oriented programming models designed for interfaces and abstract classes, providing greater flexibility and independence between subsystems in their implementation
- Utilisation of abstract classes to extract common functionality, extending the flexibility offered by interfaces
The Role of Static and Dynamic Objects in the Application Model
- Static Java classes and their dynamic properties
- Distinguishing the functionality of both entity types within Java, including typical uses and examples of good practice in designing solutions based on static and dynamic Java entities
- Introduction to design patterns
- Introduction to the Factory design pattern
Operations with Primitive Types and Wrapper Classes
- Essential 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 typical applications of these types in applications
Special Java Objects: The String Class, StringBuilder, and StringBuffer
Recapping the fundamental properties of the String class and discussing how String objects are handled by the virtual machine
The use of buffer classes and operations on character sequences
Formatting, Parsing, and Regular Expressions
- Introduction to regular expressions in Java
- Discussion of both basic techniques for handling regular expressions (using the String class) as well as advanced techniques based on dedicated classes for this purpose
- Tokenisation, 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, wrapper classes, and buffered streams
- Opening, closing, and writing to files and sockets
Inner Classes – Detailed Discussion
- Discusses how to implement and use inner classes in Java, as well as anonymous classes
Threads – Detailed Discussion, Applications, and Issues
- Discussion on thread topics ranging from the abstraction mechanism of threads in Java to thread synchronization and connecting threads in groups, aiming to present and discuss common problems related to thread operation, such as deadlocks
Java Reflection – Introduction and Applications
- Introduction to the Java reflection mechanism
- Topics covered include the implementation of reflection in Java, loading and running class methods, instantiating classes, and examining the structure of classes
Java Serialization
- Introduction to Java object serialization
- What is serialization, how to serialize an object, handling objects that depend on each other, and how to avoid common issues associated with these concepts
- Typical uses illustrated with examples of serialization and RMI CORBA
