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
- Grading levels of Java object-oriented abstraction.
- Comprehensive object modeling in Java.
- Application design patterns that leverage interfaces and abstract classes to enhance flexibility and decouple subsystems from one another.
- Utilizing abstract classes to extract common functionality while extending the flexibility provided by interfaces.
The Role of Static and Dynamic Objects in Application Models
- Static Java classes and the dynamic properties associated with these classes.
- Understanding the functional distinctions between static and dynamic entities in Java, their typical use cases, and best practices for designing solutions based on both.
- 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 their typical application scenarios.
Special Java Objects: String, StringBuilder, and StringBuffer
Review of the fundamental properties of the String class and an analysis of how the Java Virtual Machine handles String objects.
Utilization of buffer classes and operations on string 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 utilizing dedicated classes for this purpose.
- Tokenization, search methods, 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 stream wrapper and buffering classes.
- Opening, closing, and writing to files and sockets.
Inner Classes: A Detailed Discussion
- Exploration of how to implement and utilize inner classes in Java, including so-called anonymous classes.
Topics: Detailed Discussion, Applications, and Challenges
- Discussion of topics ranging from the abstraction mechanisms of threads in Java to thread synchronization and connecting threads within a group. The course also addresses common thread-related issues, such as deadlocks.
Java Reflection: Introduction and Applications
- Introduction to the Java reflection mechanism.
- Topics include the implementation of reflection in Java, loading and invoking class methods, instantiating classes, and inspecting class structures.
Java Serialization
- Introduction to Java object serialization.
- Understanding what serialization is, how to serialize objects, handling interdependent objects, and avoiding common problems associated with this process.
- Typical use cases for serialization, including examples with RMI and CORBA.
Requirements
Participants must have knowledge of the concepts covered in the Java Fundamentals course.
