Course Outline
Abstract Class
- Principles of declaration and implementation for abstract classes
- Common issues arising when working with abstract classes
The Role of Classes, Abstract Classes, and Interfaces in the Application Model
- Levels of object-oriented abstraction in Java
- The comprehensive object model in Java
- Leveraging interfaces, abstract classes, and standard classes to enhance application flexibility and ensure independence among subsystems during implementation
- Utilizing abstract classes to extract shared functionality, complemented by the flexibility provided by interfaces
The Role of Dynamic and Static Objects in the Application Model
- Static Java classes and the dynamic properties associated with them
- Distinguishing the functional differences between static and dynamic entities in Java, including typical use cases and best practices for designing solutions based on these concepts
- An introduction to design patterns
- An overview of the factory design pattern
Operations with Simple Types and Wrapper Classes
- Key facts and techniques for expanding the utility of primitive types within the Java object model
- The role of wrapper classes for primitive types and their typical applications
Special Java Objects: String, StringBuilder, and StringBuffer Classes
Review of the fundamental properties of the String class and an analysis of how the virtual machine handles String objects.
Utilizing buffer classes for efficient string manipulation.
Formatting, Parsing, and Regular Expressions
- Introduction to regular expressions in Java
- Basic techniques for handling regular expressions via the String class, alongside advanced methods using dedicated utility classes
- String tokenization, searching, and pattern matching
I/O Operations
- In-depth exploration of Java I/O mechanisms, including streams, Writer and Reader classes, wrapper classes, and buffered streams
- File and socket operations, covering opening, closing, and writing processes
Inner Classes - Detailed Discussion
- Implementation and usage of inner classes in Java, including anonymous classes
Threads - Detailed Discussion, Applications, and Challenges
- Comprehensive coverage of thread topics, ranging from thread abstraction mechanisms in Java to thread synchronization and grouping. The course addresses common concurrency issues, such as deadlocks.
Java Reflection - Introduction and Application
- Introduction to the Java reflection mechanism
- Discussion of reflection implementation, including method loading and execution, class instantiation, and inspecting class structures
Java Serialization
- Introduction to Java object serialization
- Defining serialization, procedures for serializing objects, handling interdependent objects, and strategies to avoid common serialization pitfalls
- Typical applications of serialization, including RMI and CORBA examples
Requirements
Proficiency in the concepts covered during the Java Fundamentals course is required.
