- 1. Advanced Java Techniques Java is a powerful and versatile programming language that continues to evolve, offering developers advanced techniques to write efficient, scalable, and high-performing applications. This presentation will dive into some of the most cutting-edge Java features and methodologies.
- 2. Multithreading and Concurrency Thread Management Effectively creating, starting, and managing multiple threads to leverage the full power of modern hardware. Synchronization Securing shared resources and avoiding race conditions through the use of locks, semaphores, and other concurrency control mechanisms. Deadlock Avoidance Designing concurrency-safe code that prevents deadlocks and other threading pitfalls for robust, bug- free applications. 1 2 3
- 3. Functional Programming with Lambdas Lambda Expressions Leveraging anonymous functions to write more concise, expressive, and functional code. Functional Interfaces Defining interfaces with a single abstract method to enable functional programming patterns. Method References Using method references as a shorthand for lambda expressions to simplify code even further.
- 4. Streams and Parallel Processing Declarative Data Processing Leveraging the Stream API to express complex data transformations in a concise, readable manner. Parallelism Harnessing the power of multiple cores and threads to speed up computationally intensive tasks. Lazy Evaluation Optimizing performance by deferring stream operations until the last possible moment. Functional Composition Chaining multiple stream operations together to create powerful data processing pipelines. 1 2 3 4
- 5. Inversion of Control Allowing the framework to manage the lifecycle and wiring of application components. Loose Coupling Promoting modularity and testability by decoupling classes from their dependencies. Annotation-based Configuration Leveraging Java annotations to simplify the configuration of beans and their dependencies. Test Isolation Mocking dependencies to enable unit testing of individual components in isolation. Dependency Injection with Spring
- 6. Test-Driven Development (TDD) Write Tests First Define the expected behavior of your code before implementation. Refactor Fearlessly Safely improve the design of your code with a comprehensive test suite. Rapid Feedback Instantly know when you've broken existing functionality. Living Documentation Tests serve as a clear, executable specification of your application.
- 7. Refactoring and Design Patterns Identify Smells Recognize anti-patterns and areas of the codebase that need improvement. Apply Patterns Utilize well-known design patterns to address common design problems. Refactor Safely Improve the internal structure of the code without changing its external behavior. 1 2 3
