Course Outline
Abstract Classes
- Principles of declaring and implementing abstract classes
- Common challenges faced when working with abstract classes
The Role of Classes, Abstract Classes, and Interfaces in Application Modeling
- Understanding levels of Java object-oriented abstraction
- The comprehensive object model in Java
- The importance of interface-oriented programming models to enhance flexibility and decouple subsystems during implementation
- Utilizing abstract classes to extract shared functionality while leveraging the flexibility offered by interfaces
The Role of Static and Dynamic Elements in Application Modeling
- Static aspects of Java classes and the dynamic properties associated with these classes
- Distinguishing functionality between static and dynamic entities in Java, including typical use cases and best practices for designing solutions based on static and dynamic constructs
- Introduction to design patterns
- Introduction to the Factory design pattern
Operations with Primitive Types and Wrapper Classes
- Key facts and techniques to enhance the use of primitive types within the Java object model
- The role of wrapper classes for primitive types and their typical applications in software development
Special Objects in Java: String, StringBuilder, and StringBuffer
Review of the fundamental properties of the String class and an analysis of how the Java Virtual Machine handles String objects.
Usage of buffer classes and operations on character sequences.
Formatting, Parsing, and Regular Expressions
- Introduction to regular expressions in Java
- Discussion of both basic techniques for handling regular expressions using the String class and advanced techniques utilizing dedicated classes for such structures
- Tokenization, search, and pattern matching for string types
I/O Operations
- A detailed discussion of Java I/O mechanisms, including stream classes, Writer and Reader classes, and the use of wrapper and buffered streams in Java
- Opening, closing, and writing to files and sockets
Inner Classes: Detailed Discussion
- Explanation of how to implement and utilize inner classes in Java, including so-called anonymous classes
Threads: Detailed Discussion, Applications, and Issues
- Discussion of thread topics ranging from Java's thread abstraction mechanisms to thread synchronization and grouping, including an overview of common thread-related problems such as deadlocks
Java Reflection: Introduction and Applications
- Introduction to the Java reflection mechanism
- Topics covered include implementing reflection in Java, loading and executing class methods, instantiating classes, and examining class structures
Java Serialization
- Introduction to Java object serialization
- Understanding what serialization is, how to serialize objects, handling interdependent objects, and avoiding common problems associated with these processes
- Typical use cases for serialization, including examples with RMI and CORBA
