Technical Skills

1. Can you explain the differences between J2EE and Spring Framework?

Understanding the distinctions between these frameworks is crucial for a role that involves Java technologies.

How to Answer

Discuss the core functionalities of both frameworks, emphasizing how Spring provides a more modular approach compared to the traditional J2EE.

Example

“J2EE is a specification that provides a standard for building enterprise applications, while Spring is a framework that simplifies Java development by providing features like dependency injection and aspect-oriented programming. Spring allows for more flexibility and modularity, making it easier to manage complex applications.”

2. What is your experience with RESTful services? Can you describe how you would design one?

This question assesses your understanding of web services and API design.

How to Answer

Outline the principles of REST and how you would implement them in a project, including considerations for statelessness and resource representation.

Example

“I have designed RESTful services using Spring Boot, focusing on stateless interactions and resource-based URLs. I ensure that each endpoint corresponds to a specific resource and uses standard HTTP methods like GET, POST, PUT, and DELETE to manipulate those resources.”

3. How do you handle multi-threading and concurrency in Java?
