Application Model: Classes, Abstract Classes, and Interfaces
- Hierarchy of Java object-oriented abstractions
- The comprehensive Java object model
- Leveraging interfaces, abstract classes, and regular classes to enhance application flexibility and ensure independence between subsystems during implementation
- Utilizing abstract classes to extract common functionality, complemented by the flexibility offered by interfaces
Dynamic vs. Static Objects in the Application Model
- Static Java classes and their dynamic attributes
- Distinguishing the functional roles of static and dynamic entities in Java, along with best practices for designing solutions based on these concepts
- Introduction to design patterns
- Overview of the Factory design pattern
Operations on Simple Types and Wrapper Classes
- Essential facts and techniques for extending the use 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
Review of fundamental String class properties and the treatment of String objects by the virtual machine
Utilizing buffer classes for string manipulation
Formatting, Parsing, and Regular Expressions
- Introduction to regular expressions in Java

Inner Classes: A Detailed Discussion
- Implementation and usage of inner classes in Java, including anonymous classes
Threads: Detailed Discussion, Applications, and Challenges
- Exploration of thread-related topics, ranging from thread abstraction mechanisms in Java to synchronization, thread grouping, and common issues such as deadlocks
Java Reflection: Introduction and Applications
- Overview of the Java reflection mechanism
- Discussion on implementing reflection in Java, including method loading and execution, class instantiation, and introspecting class structures
