Course Outline
Abstract Classes
- Principles of declaration and implementation for abstract classes
- Common challenges encountered when working with abstract classes
The Role of Classes, Abstract Classes, and Interfaces in Application Architecture
- Understanding levels of Java object-oriented abstraction
- An overview of the complete object model in Java
- Leveraging interfaces and abstract classes in application design to achieve greater flexibility and decouple subsystems from one another during implementation
- Utilizing abstract classes to extract shared functionality while maintaining the flexibility provided by interfaces
The Role of Static and Dynamic Elements in Application Architecture
- Understanding static Java classes and their dynamic characteristics
- Distinguishing between the functionalities of both entity types within Java, including typical use cases and best practices for designing solutions based on static and dynamic constructs
- Introduction to design patterns
- Introduction to the Factory design pattern
Operations with Primitive Types and Wrapper Classes
- Key facts and techniques for extending the use of primitive types within the Java object model
- Examining the role of wrapper classes for primitive types and their typical application scenarios
Special Java Objects: String, StringBuilder, and StringBuffer
Reviewing the fundamental properties of the String class and discussing how the Java Virtual Machine handles String objects.
Utilizing buffer classes and performing operations on character sequences.
Formatting, Parsing, and Regular Expressions
- Introduction to regular expressions in Java
- Exploring both basic techniques for handling regular expressions (using the String class) and advanced techniques utilizing dedicated classes for this purpose
- Tokenization, searching, and pattern matching for string data types
I/O Operations
- A detailed discussion of Java I/O mechanisms, including stream classes, the Writer and Reader classes, and Java stream wrapper and buffering techniques.
- Managing the opening, closing, and writing to files and sockets
Inner Classes - Detailed Overview
- Exploring the implementation and usage of inner classes in Java, as well as anonymous classes
Threads - Detailed Overview, Applications, and Challenges
- Discussing thread topics ranging from Java's thread abstraction mechanisms to thread synchronization and grouping. This includes presenting thread pools and analyzing 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, class instantiation, 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 pitfalls associated with these tasks
- Typical use cases for serialization, including examples involving RMI and CORBA
