Course Outline
Abstract Classes
- Principles for declaring and implementing abstract classes
- Common issues encountered when working with abstract classes
The Role of Classes, Abstract Classes, and Interfaces in the Application Model
- Understanding Java object-oriented abstraction levels
- Comprehensive view of the Java object model
- Programmatic approaches to using interfaces and abstract classes to enhance application flexibility and decouple subsystems from each other
- Utilizing abstract classes to share common functionality while leveraging the flexibility provided by interfaces
The Role of Static and Dynamic Objects in the Application Model
- Static Java classes and their dynamic properties
- Distinguishing between the functionality of both entity types in Java, including typical use cases and best practices for designing solutions based on static and dynamic Java entities
- 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
- Discussion on the role of wrapper classes for primitive types and their typical application scenarios
Special Java Objects: The String, StringBuilder, and StringBuffer Classes
Recap of the String class's basic properties and an overview of how the Java Virtual Machine (JVM) handles String objects.
Using buffer classes and manipulating character sequences.
Formatting, Parsing, and Regular Expressions
- Introduction to regular expressions in Java
- Discussion of basic techniques for handling regular expressions (using the String class) as well as advanced techniques utilizing dedicated classes for this purpose
- Tokenization, search, and pattern matching for string types
I/O Operations
- Detailed discussion of Java I/O mechanisms, including stream classes, Writer and Reader classes, wrapper classes, and buffering streams in Java.
- Opening, closing, and writing to files and sockets
Inner Classes - Detailed Discussion
- How to implement and use inner classes in Java, including anonymous classes
Concurrency - Detailed Discussion, Applications, and Issues
- Discussion on concurrency topics ranging from Java's thread abstraction mechanisms to thread synchronization and grouping threads. This section also presents common thread-related problems, such as deadlocks
Java Reflection - Introduction and Applications
- Introduction to the Java reflection mechanism
- Topics include implementing reflection in Java, loading and executing class methods, instantiating classes, and exploring class structures
Java Serialization
- Introduction to Java object serialization
- Understanding what serialization is, how to serialize objects, handling dependent objects, and avoiding common issues associated with this process
- Typical use cases, including examples involving serialization and RMI CORBA
Requirements
