Course Outline
Abstract Classes
- Principles of declaration and implementation of abstract classes
- Common issues encountered when working with abstract classes
The Role of Classes, Abstract Classes, and Interfaces in Application Modeling
- Understanding Java object-oriented abstraction levels
- Overview of the complete object model in Java
- Programmatic approaches for interfaces and abstract classes to enhance application flexibility and decouple sub-systems
- Utilizing abstract classes to extract common functionality while leveraging the flexibility provided by interfaces
The Role of Static and Dynamic Objects in Application Modeling
- Static Java classes and their dynamic characteristics
- Distinguishing functionality between both entity types in Java, along with typical use cases and best practices for designing solutions based on static and dynamic entities
- Introduction to design patterns
- Introduction to the Factory design pattern
Operations with Primitive Types and Wrapper Classes
- Key facts and techniques to extend 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: String, StringBuilder, and StringBuffer
Review of the fundamental properties of the String class and how the virtual machine handles String objects
Utilizing buffer classes and performing operations on string sequences
Formatting, Parsing, and Regular Expressions
- Introduction to regular expressions in Java
- Discussion of basic techniques for handling regular expressions (using the String class) as well as advanced techniques involving dedicated classes for this purpose
- Tokenization, search, and pattern matching for string types
I/O Operations
- In-depth discussion of Java I/O mechanisms, including streaming classes, Writer and Reader classes, and the use of wrapper and buffering streams
- Opening, closing, and writing to files and sockets
Inner Classes: Detailed Discussion
- Explores the implementation and usage of inner classes in Java, including so-called anonymous classes
Topics: Detailed Discussion, Applications, and Issues
- Discussion on threading topics, ranging from the thread abstraction mechanism in Java to thread synchronization and grouping. The session also addresses common threading issues, such as deadlocks.
Java Reflection: Introduction and Application
- Introduction to the Java reflection mechanism
- Lecture topics include implementing reflection in Java, loading and executing class methods, instantiating classes, and inspecting class structures
Java Serialization
- Introduction to Java object serialization
- Understanding what serialization is, how to serialize objects, handling dependent objects, and avoiding common issues associated with these operations
- Typical use cases for serialization, such as in RMI and CORBA
Requirements
Participants should possess knowledge of the topics covered in the Java Fundamentals course.
