  • Explain core Java and Spring fundamentalsEasy

    This question evaluates core competencies in Java and Spring, covering data structures and collections, object-oriented design (SOLID), hash-based collections and concurrency primitives, immutability and string handling, exception handling, Spring IoC/DI and AOP, bean lifecycle and annotations, and functional collection processing via the Stream API. Commonly asked in Software Engineering Fundamentals interviews for backend Java/Spring roles, it checks both conceptual understanding and practical application by assessing architectural reasoning, concurrency and thread-safety knowledge, and familiarity with framework conventions and APIs.
