Course Outline
Abstract Class
- Principles for 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
- Understanding Java object-oriented abstraction levels
- The complete object model in Java
- Programmatic approaches leveraging interfaces and abstract classes to enhance application flexibility and achieve loose coupling between subsystems
- Utilizing abstract classes to extract shared functionality, complementing the flexibility provided by interfaces
The Role of Static and Dynamic Objects in the Application Model
- Characteristics of Java static classes and the dynamic attributes associated with them
- Differentiating the functionality of both entity types in Java, including typical use cases and best practices for designing solutions based on static and dynamic elements
- Introduction to design patterns
- Introduction to the Factory design pattern
Operations with Primitive Types and Wrapper Classes
- Key facts and techniques for extending the utility of primitive types within the Java object model
- The role of wrapper classes for primitive types and their typical applications in software
Special Java Objects: String, StringBuilder, and StringBuffer
Reviewing the fundamental properties of the String class and discussing how the virtual machine handles String objects
Utilizing buffer classes and operations on character 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 utilizing dedicated classes
- Tokenization, search, and pattern matching for string types
I/O Operations
- A detailed examination of Java I/O mechanisms, including stream classes, Writer and Reader classes, and the wrapping and buffering of Java streams
- Opening, closing, and writing to files and sockets
Inner Classes - Detailed Discussion
- Methods for implementing and using inner classes in Java, including anonymous classes
Threading - Detailed Discussion, Applications, and Challenges
- Comprehensive discussion of threading mechanisms in Java, ranging from thread abstraction to synchronization and connecting threads in groups. The course also addresses common threading problems, 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 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 issues associated with serialization
- Typical use cases for serialization, including examples from RMI and CORBA
Requirements
Prerequisite knowledge from the Java Fundamentals course.
