Most Frequently asked Interview Questions of api(2024)

An API (Application Programming Interface) is a set of rules and protocols that allow different software applications to communicate with each other. It defines the methods and data formats that applications can use to request and exchange information.

An endpoint in an API is a specific URL (Uniform Resource Locator) that corresponds to a particular resource or a set of actions that can be performed using an HTTP request. It is the point of entry through which an API interacts with other systems, enabling them to communicate and exchange data.

In RESTful API design, idempotent and safe methods refer to how HTTP methods behave with respect to repeated requests and the safety of side effects they may cause. Understanding these concepts is important for designing APIs that are reliable, predictable, and user-friendly.

In RESTful APIs, the response format is crucial because it defines how the server sends data back to the client. While REST itself is agnostic to the format, most modern APIs use common formats that are standardized and widely supported. Below are the most common response formats used in RESTful APIs:

JSON (JavaScript Object Notation) and XML (eXtensible Markup Language) are two popular data formats used for exchanging information between a client and server in web APIs. Both serve as a medium for representing data structures in a readable format that can be easily parsed by machines, but they differ in structure, readability, and use cases.

OAuth (Open Authorization) is an open standard for access delegation commonly used to grant third-party applications limited access to resources without exposing the user's credentials. It is widely used to allow users to grant access to their data from one service to another without sharing their login details, ensuring secure and controlled access to their data.

Securing an API is critical to protect sensitive data, prevent unauthorized access, and ensure that the API behaves as expected. A well-secured API guards against common vulnerabilities and ensures that only authorized users or systems can access or modify resources. Below are the best practices and techniques for securing an API:

Authentication in a RESTful API is a critical aspect of ensuring secure access to resources and protecting sensitive data. Since RESTful APIs are stateless by design, authentication mechanisms need to work in a way that does not rely on maintaining session state on the server between requests. This means the client must provide some form of credentials with each request to verify the user’s identity.

Most Frequently asked rest Interview Questions and Answers

In RESTful services, the HTTP methods GET, POST, PUT, and DELETE are used to perform various operations on resources, corresponding to the basic CRUD (Create, Read, Update, Delete) operations. Each method serves a specific purpose, and understanding the differences is crucial for designing and interacting with RESTful APIs.

REST (Representational State Transfer) and SOAP (Simple Object Access Protocol) are both web service communication protocols used for data exchange, but they have several key differences in their design, implementation, and usage.

Most Frequently asked Interview Questions of hibernate

Hibernate Query Language (HQL) is a database-independent query language used in Hibernate for querying the database. HQL is similar to SQL (Structured Query Language) but it operates on objects rather than database tables, and it is designed to work seamlessly with the object-oriented nature of Hibernate. HQL allows you to write queries that interact with Java objects (entities) rather than database tables and columns directly, which helps in maintaining a layer of abstraction between the application and the database.

Most Frequently asked hibernate Interview Questions and Answers

Hibernate Mapping refers to the process of defining the relationship between Java objects (or entities) and database tables in Hibernate. Hibernate, as an Object-Relational Mapping (ORM) framework, allows developers to map Java classes to database tables and manage the data between them seamlessly. This process involves defining how Java objects (entities) are represented in the database and vice versa, which includes relationships, primary keys, columns, and other constraints.

Most Frequently asked hibernate Interview Questions

Hibernate is an Object-Relational Mapping (ORM) framework for Java that simplifies database interactions by mapping Java objects to relational database tables. It eliminates the need for developers to write complex SQL code manually for common database operations like CRUD (Create, Read, Update, Delete). Hibernate automatically handles the conversion between Java objects and database records, making it easier to interact with relational databases in an object-oriented manner.
