Graceful Shutdown in Spring
This blog post will take a deep dive into spring.lifecycle.timeout-per-shutdown-phase, and explore the broader context of graceful shutdowns with real
Q4. What is lazy evaluation in Streams? Streams are lazily evaluated, meaning intermediate operations are not executed until a terminal operation is invoked. This enables efficient computation. #JavaInspires

Designing a Distributed Caching Strategy
This detailed blog post explores distributed caching, explains why preventing stale data matters, and provides a step-by-step approach to designing an
Q13. What is the difference between findFirst() and findAny()? - findFirst() returns the first element in encounter order. - findAny() may return any element, optimized for parallel execution. #JavaInspires
Q6. What is the difference between map() and flatMap()? - map() transforms each element individually and returns a Stream of elements. - flatMap() flattens nested Streams into a single Stream, useful for handling collections within collections. #JavaInspires
Q11. What happens if a Stream is reused after a terminal operation? A Stream cannot be reused. Once a terminal operation is executed, the Stream is considered consumed and closed. #JavaInspires
Q15. What are short-circuiting operations? These are operations that may terminate early without processing all elements, like findFirst(), anyMatch(), allMatch(), and noneMatch(). #JavaInspires
Q14. Can a Stream handle null values? No, passing null to Stream operations (like Stream.of(null)) will throw a NullPointerException. #JavaInspires
Q13. What is the difference between findFirst() and findAny()? - findFirst() returns the first element in encounter order. - findAny() may return any element, optimized for parallel execution. #JavaInspires
Q12. How does the reduce() operation work? It performs a reduction on stream elements using an associative accumulation function and returns an Optional or a specified identity value. #JavaInspires
Q11. What happens if a Stream is reused after a terminal operation? A Stream cannot be reused. Once a terminal operation is executed, the Stream is considered consumed and closed. #JavaInspires
Q10. What are some common terminal operations? collect(), forEach(), count(), reduce(), min(), max(), and findFirst(). #JavaInspires
Q9. What is the advantage of using parallel streams? Parallel streams divide the stream elements into multiple substreams processed concurrently, leveraging multi-core processors for better performance on large datasets. #JavaInspires
Q8. What does the filter() method do? It filters elements based on a given predicate, returning a Stream containing only the elements that match the condition. #JavaInspires
Q7. How can you convert a Stream to a List or Set? Use collectors:#JavaInspires List<String> list = stream.collect(Collectors.toList()); Set<Integer> set = stream.collect(Collectors.toSet());
Q6. What is the difference between map() and flatMap()? - map() transforms each element individually and returns a Stream of elements. - flatMap() flattens nested Streams into a single Stream, useful for handling collections within collections. #JavaInspires
Q5. How do you create a Stream in Java? Common ways include: - Using collection.stream() or collection.parallelStream() - Using Stream.of() for fixed elements - Using Arrays.stream(array) - Using Stream builders or generators. #JavaInspires
Q4. What is lazy evaluation in Streams? Streams are lazily evaluated, meaning intermediate operations are not executed until a terminal operation is invoked. This enables efficient computation. #JavaInspires
Q3. What are intermediate and terminal operations in Streams? Intermediate operations: Return another Stream (e.g., map, filter, distinct, sorted). Terminal operations: Produce a result or side-effect (e.g., collect, forEach, reduce). #JavaInspires
Q2. How is a Stream different from a Collection? Collections store data, while Streams process data. Streams do not store elements; they provide a pipeline to handle data from a source like a collection, array, or I/O channel. #JavaInspires
Q1. What is a Stream in Java? A Stream is a sequence of elements supporting functional-style operations. It allows processing data declaratively using operations like map, filter, and reduce without modifying the underlying data source. #JavaInspires
