BD Unit 6 Sprint 23
Sprint Overview
Welcome to BD Unit 6 Sprint 23! This sprint covers three key topics in Java development: threads and concurrency, AWS CloudWatch metrics, and lambda expressions. These advanced concepts will help you build more efficient, maintainable, and observable applications.
By the end of this sprint, you'll be able to implement concurrent programming solutions, monitor application performance with custom metrics, and write cleaner code using functional programming techniques.
Module 1: Introduction to Threads
Learn about Java threads and concurrent programming basics.
Key Topics
- Understand thread lifecycle states
- Create threads using Thread class and Runnable interface
- Implement thread synchronization
- Manage race conditions
Module 2: Metrics
Explore AWS CloudWatch metrics and application monitoring.
Key Topics
- Work with CloudWatch namespaces and dimensions
- Implement custom metrics in Java applications
- Use metrics to identify performance issues
- Analyze percentile-based metrics (p50, p90, p99)
Module 3: Java Lambda Expressions
Master lambda expressions and functional programming in Java.
Key Topics
- Implement functional interfaces
- Use built-in interfaces like Function, Consumer, Predicate, and Supplier
- Apply method references for more concise code
- Work with the Stream API for data processing
Module 4: Unit Review
Review and reinforce concepts from the entire sprint.
Key Topics
- Revisit key threading concepts
- Review CloudWatch metrics usage
- Reinforce lambda and functional programming
- Prepare for the sprint challenge
