Course Outline
Abstract Classes
- Principles of declaration and implementation of abstract classes
- Common challenges encountered when working with abstract classes
The Role of Classes, Abstract Classes, and Interfaces in Application Models
- Levels of object-oriented abstraction in Java
- The complete object model in Java
- Application models oriented toward interfaces and abstract classes to increase flexibility and ensure subsystem independence during implementation
- Utilizing abstract classes to extract common functionality, combined with the flexibility offered by interfaces
The Role of Dynamic and Static Objects in Application Models
- Static Java classes and the dynamic properties of these classes
- Distinguishing the functionality of static and dynamic entities in Java, including typical use cases and best practices in solution design
- Introduction to design patterns
- Introduction to the factory design pattern
Operations with Simple Types and Wrapper Classes
- Key facts and techniques for extending the use of simple types within the Java object model
- The role of wrapper classes for simple types and their typical applications
Special Java Objects: String, StringBuilder, and StringBuffer
Review of the basic properties of the String class and an examination of how String objects are managed by the virtual machine
Utilizing buffer classes and performing operations on string chains
Formatting, Parsing, and Regular Expressions
- Introduction to regular expressions in Java
- Basic techniques for handling regular expressions using the String class, as well as advanced techniques employing dedicated classes
- 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, wrapper classes, and buffering streams
- Opening, closing, and writing to files and sockets
Inner Classes – Detailed Discussion
- Implementing and using inner classes in Java, including so-called anonymous classes
Threads – Detailed Discussion, Applications, and Issues
- Topics ranging from thread abstraction mechanisms in Java to synchronization, thread grouping, and common issues such as deadlocks
Java Reflection – Introduction and Application
- Introduction to the Java reflection mechanism
- Discussion on implementing reflection in Java, loading and executing class methods, instantiating classes, and inspecting class structures
Java Serialization
- Introduction to Java object serialization
- Definition of serialization, methods for serializing objects, handling interdependent objects, and avoiding common pitfalls
- Typical use cases, including examples of serialization with RMI and CORBA
Requirements
