Course Outline
Abstract Classes
- Principles of declaring and implementing abstract classes
- Common issues encountered when working with abstract classes
The Role of Classes, Abstract Classes, and Interfaces in Application Models
- Levels of Java object-oriented abstraction
- The complete object model in Java
- Programmatic models leveraging interfaces and abstract classes to provide greater flexibility and independence between subsystems in their implementation
- Utilizing abstract classes to extract common functionality, extending the flexibility offered by interfaces
The Role of Static and Dynamic Elements in Application Models
- Static Java classes and the dynamic properties of these classes
- Distinguishing between the functionality of both types of entities within Java, their typical uses, and examples of best practices in designing solutions based on static and dynamic Java elements
- Introduction to design patterns
- Introduction to the Factory design pattern
Operations with Primitive Types and Wrapper Classes
- Essential facts and techniques to extend the use of primitive types within the Java object model
- The role of wrapper classes for primitive types and their typical applications in software development
Special Java Objects: The String, StringBuilder, and StringBuffer Classes
Review of the basic properties of the String class and the management of String objects 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) and advanced techniques based on dedicated classes for this purpose
- Tokenization, search, and pattern matching for string types
I/O Operations
- A detailed discussion of Java I/O mechanisms, including class streams, Writer and Reader classes, and Java stream wrapper and buffering classes
- Opening, closing, and writing to files and sockets
Inner Classes - Detailed Discussion
- How to implement and use inner classes in Java, as well as so-called anonymous classes
Threads - Detailed Discussion, Applications, and Challenges
- Discussion on thread topics, ranging from the thread abstraction mechanism in Java to thread synchronization and connecting threads in groups. It also covers thread pools and presents common problems related to thread execution, such as deadlocks
Java Reflection - Introduction and Application
- Introduction to the Java reflection mechanism
- Topics include the implementation of reflection in Java, loading and executing methods of classes, class instantiation, and examining class structures
Java Serialization
- Introduction to Java object serialization
- Understanding what serialization is, how to serialize an object, handling objects dependent on each other, and avoiding common problems associated with these issues
- Typical uses, exemplified by serialization and RMI CORBA
Requirements
