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 the Application Model
- Levels of object-oriented abstraction in Java
- The comprehensive object model in Java
- An application-oriented model for interfaces and abstract classes that enhances flexibility and ensures independence between sub-systems in their implementation
- Utilizing abstract classes to extract common functionality, complemented by the flexibility offered through interfaces
The Role of Dynamic and Static Objects in the Application Model
- Static Java classes and the dynamic properties of these classes
- Distinguishing the functionality of static and dynamic entities within Java, along with their typical use cases and best practice examples 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
A review of the basic properties of the String class and an analysis of how String objects are handled by the virtual machine
The use of buffer classes and operations on 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
- Tokenization, search, and pattern matching for string types
I/O Operations
- A detailed examination 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 anonymous classes
Threading - Detailed Discussion, Applications, and Challenges
- Comprehensive discussion of threading topics, ranging from thread abstraction mechanisms in Java to thread synchronization and group connection, covering common issues such as deadlocks
Java Reflection - 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 what serialization is, how to serialize objects and dependent objects, and strategies to avoid common issues
- Typical use cases of serialization in RMI and CORBA
Requirements
A solid understanding of the concepts covered in the Java Fundamentals course is required.
