- Common challenges faced 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
- Programming models for interfaces and abstract classes that enhance application flexibility and ensure independence among sub-systems during implementation
- Using abstract classes to extract common functionality and leveraging the flexibility offered by interfaces for implementation
The Role of Dynamic and Static Objects in the Application Model
- Static Java classes and their dynamic properties
- Distinguishing between the functionalities of static and dynamic entities, with typical uses and best practices for 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 how String objects are managed by the virtual machine
Utilizing buffer classes and performing operations on character sequences
Formatting, Parsing, and Regular Expressions
- Introduction to regular expressions in Java
- Comparison of basic techniques (using the String class) and advanced techniques (using dedicated classes) for handling regular expressions
- Tokenization, search, and pattern matching for string types
I/O Operations

- Opening, closing, and writing to files and sockets
Inner Classes: Detailed Discussion
- Implementation and usage of inner classes and anonymous classes in Java
Threads: Detailed Discussion, Applications, and Challenges
- Comprehensive overview of threading topics, from abstraction mechanisms to synchronization and thread groups, addressing common issues such as deadlocks
Java Reflection: Introduction and Application
- Overview of the Java reflection mechanism
- Discussion on implementing reflection in Java, including loading and executing methods, instantiating classes, and inspecting class structures
Java Serialization
- Introduction to Java object serialization
- Understanding what serialization is, how to serialize objects and dependencies, and strategies to avoid common pitfalls
- Typical use cases, including serialization with RMI and CORBA
Requirements
