Junior Java Developer Interviews

Junior Java Developer Interview Questions

"Junior developers are often responsible for writing the more monotonous and simple code required by senior members of the development team. Because of this, interviews will be designed to test your knowledge of the fundamentals of Java so be prepared to answer technical questions that you likely came across in college. Data structures and algorithms will be heavily emphasised. A bachelor's degree or equivalent work experience is required. "

What is Spring Boot? How does it simplify the development of Java applications? Answer: Spring Boot is a framework that simplifies the development of Java-based applications by providing pre-configured setups and conventions. It eliminates the need for manual configuration and boilerplate code, allowing developers to quickly set up and deploy production-ready applications with minimal effort. Can you explain the concept of microservices architecture? How does it differ from monolithic architecture? Answer: Microservices architecture is an architectural style that structures an application as a collection of loosely coupled services, each responsible for performing a specific business function. These services are independently deployable and scalable. In contrast, monolithic architecture is a traditional approach where all components of the application are tightly integrated into a single codebase, making it difficult to scale and maintain.
