Quick study sessions to strengthen memory and retain key concepts.
How can Reflection be used in dynamic frameworks?
Reflection allows frameworks to dynamically map and invoke methods. Frameworks like Spring use reflection to dynamically map HTTP…
View Card →Why is Reflection considered a security risk?
Reflection can expose private fields and methods to unauthorized access. Reflection can be leveraged to bypass normal access…
View Card →How does setAccessible(true) affect encapsulation?
It bypasses the access control restrictions, allowing access to private fields or methods. Using `setAccessible(true)` on a Field…
View Card →What does Reflection allow you to inspect in Java?
Reflection allows you to inspect classes, interfaces, fields, and methods at runtime. Reflection in Java provides the ability…
View Card →How would you explain the danger of reflective business logic in an interview?
It creates string-coupled runtime behavior that is harder to refactor safely. When business code depends on reflective lookups…
View Card →What are the trade-offs between WebFlux and procedural Java 21 code?
WebFlux offers high scalability but is complex; Java 21 is simpler but less scalable. WebFlux provides high concurrency…
View Card →Why does `request(n)` in Reactive Streams matter in practice?
It allows Subscribers to request a specific number of items. The `request(n)` method in Reactive Streams lets a…
View Card →How do functional pipelines operate in Project Reactor?
They transform data streams using functions like map and flatMap. Project Reactor uses functional pipelines to process data…
View Card →Describe how WebFlux differs from Virtual Threads in handling concurrency?
WebFlux uses event-driven non-blocking I/O, Virtual Threads use lightweight threads. WebFlux employs non-blocking I/O to handle multiple requests…
View Card →Why is blocking the Event Loop in WebFlux risky in production code?
Blocking can lead to performance bottlenecks. Blocking operations in a WebFlux event loop can halt other tasks, reducing…
