Course Outline
Abstract Classes
- Principles of declaring and implementing abstract classes
- Common problems 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 complete object model in Java
- Program design oriented towards interfaces and abstract classes to enhance application flexibility and the independence of each subsystem from others during implementation
- The use of abstract classes to extract common functionality, extending the flexibility offered by interfaces
The Role of Static and Dynamic Elements in the Application Model
- Static Java classes and the dynamic properties of these classes
- Distinguishing the functionality of both types of entities within Java, including 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
- Key facts and techniques to extend the use of primitive types within the Java object model
- Discussion on the role of wrapper classes for primitive types and their typical applications in software
Special Java Objects: The String Class, StringBuilder, and StringBuffer
Review of the basic properties of the String class and a discussion on how the Java Virtual Machine handles String objects
The use of buffer classes and operations on character chains
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 stream classes, Writer and Reader classes, and classes for wrapping and buffering Java 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
Topics - Detailed Discussion, Applications, and Challenges
- Discussion on topics ranging from the abstraction mechanism of threads in Java to thread synchronization and connecting threads in a group. It also presents and discusses common thread pool problems, such as deadlocks
Java Reflection - Introduction and Applications
- Introduction to the Java reflection mechanism
- Topics include the implementation of reflection in Java, loading and running class methods, instantiating classes, and exploring class structures
Java Serialization
- Introduction to Java object serialization
- Understanding what serialization is, how to serialize an object, handling objects that depend on each other, and how to avoid common problems associated with these issues
- Typical uses with examples such as serialization and RMI CORBA
Requirements
Participants should have prior knowledge of the concepts discussed in the Java Fundamentals course.
