GraphQL and REST are both approaches to API design. GraphQL provides a more flexible way to request and retrieve data, allowing clients to specify their data requirements. In contrast, REST uses fixed endpoints for data retrieval, leading to over-fetching or under-fetching of data. GraphQL is better suited for modern, dynamic applications, while REST is more traditional and rigid in its structure.

15. Is there a way to decrease the load time of a web application?

Yes, several methods can reduce the load time of a web application, such as optimizing images, using external CSS and JavaScript files, reducing redirects, enabling browser caching, minifying code, and employing content delivery networks (CDNs). These techniques improve performance and enhance user experience.

16. What is Spring Framework, and how does it work?

The Spring Framework is a Java-based framework used for building enterprise-level applications. It simplifies development by providing dependency injection, aspect-oriented programming, and data access. Spring promotes modularity, testability, and scalability. Which makes it a preferred choice for creating robust and maintainable software.

17. What is REST API, and how does it work?

A REST API, stands for Representational State Transfer Application Programming Interface. It is a design style for building networked applications. It relies on HTTP requests to perform basic operations like creating, reading, updating, and deleting resources identified by URLs. REST APIs are stateless, which means every client request must contain all the necessary information. They’re used for web-based applications and services.

18. What is the difference between a servlet and JSP?

A servlet is a Java class that handles requests and generates responses on the server-side. It is primarily responsible for processing logic and business operations. In contrast, JSP (JavaServer Pages) is a technology for creating dynamic web pages. JSP combines HTML or XML with Java code to generate dynamic content for web applications. Servlets are more suitable for complex processing, while JSP simplifies the presentation layer.

19. Explain the difference between JDBC and Hibernate?

JDBC, or Java Database Connectivity, is a Java API used for connecting and interacting with relational databases. It involves manual SQL query writing and database interaction. On the other hand, Hibernate is an Object-Relational Mapping (ORM) framework that automates database interactions by mapping Java objects to database tables. Hibernate eliminates the need for manual SQL coding, simplifying database operations.

20. How do you handle exceptions in Java?

In Java, exceptions are handled using try-catch blocks. Code that might throw exceptions is placed within a try block, and specific exceptions are caught and handled in catch blocks. Developers can specify different catch blocks for different exception types, allowing for precise error handling. Additionally, the “finally” block can be used to execute code that should run regardless of whether an exception occurred or not. Exception handling ensures graceful error recovery and better program stability.
