Course Outline
Abstract classes
- Principles of declaration and implementation of abstract classes
- Common issues encountered 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 complete object model in Java
- An application model oriented around interfaces, abstract classes, and standard classes to enhance flexibility and ensure independence among sub-systems in their implementation
- Using abstract classes to extract common functionality, extended by the flexibility offered by interfaces
The role of dynamic and static objects in the application model
- Static Java classes and their dynamic properties
- Distinguishing the functionality of static and dynamic entities in Java, along with typical use cases and best practices for designing solutions based on these types of 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
- The role of wrapper classes for primitive types and their typical applications
Special Java Objects: String, StringBuilder, and StringBuffer
Review the basic properties of the String class and how the virtual machine handles String objects
Utilizing buffer classes for string manipulation
Formatting, parsing, and regular expressions
- Introduction to regular expressions in Java
- Comparison of basic techniques for handling regular expressions (using the String class) versus advanced techniques utilizing dedicated classes
- Tokenization, search, and pattern matching for string data
I / O operations
- Detailed analysis of Java I / O mechanisms, including Stream, Writer, Reader, wrapper classes, and buffered streams
- Opening, closing, and writing to files and sockets
Inner classes - detailed discussion
- Implementing and utilizing inner classes and anonymous classes in Java
Threading - detailed discussion, applications, and problems
- Comprehensive discussion on threading topics, ranging from Java thread abstraction mechanisms to thread synchronization and grouping, including analysis of common concurrency issues such as deadlocks
Java Reflections - Introduction and application
- Introduction to the Java reflection mechanism
- Topics include the implementation of reflection in Java, loading and executing class methods, instantiating classes, and inspecting class structures
Java Serialization
- Introduction to Java object serialization
- Understanding serialization, the process of serializing objects, handling interdependent objects, and avoiding common serialization pitfalls
- Typical use cases involving serialization, including RMI and CORBA
