Gain insights into the key components and technologies involved, equipping you to build robust and scalable back-end solutions.

• Java

Java is a widely used programming language for back-end development. It provides a robust and scalable environment for building enterprise-level applications. For websites that generate a lot of traffic, Java works the best since it can handle the traffic.

• Spring Framework

The Spring Framework is a popular Java framework that simplifies the development of Java applications. Being an open-source framework for building enterprise Java applications, it offers features like dependency injection, aspect-oriented programming, and support for various modules like Spring MVC (Model-View-Controller) for building web applications.

• RESTful APIs

REST is an abbreviation of Representational State Transfer (REST) which is an architectural style used for designing networked applications. RESTful APIs provide a standardized way of communication between the front end and back end. In Java, it enables the development of scalable and interoperable web services by leveraging the HTTP protocol and standardized principles.  Full-stack Java developers work with frameworks like Spring Boot to create RESTful APIs. RESTful APIs use HTTP methods (GET, POST, PUT, DELETE) to perform operations on resources (data).

• Databases

Relational databases like MySQL, PostgreSQL, or Oracle, and NoSQL databases like MongoDB or Redis, are commonly used in back-end development. A full-stack Java developer needs to understand database concepts, design data schemas, and write SQL queries to interact with databases effectively. This involves carefully defining tables, relationships, and indexes to minimize redundancy and ensure data integrity.

Furthermore, proficiency in writing SQL queries is essential for extracting, updating, and manipulating data in relational databases. It involves utilizing SQL statements such as SELECT, INSERT, UPDATE, DELETE, and JOIN to retrieve specific data, perform aggregations, and modify the database content.

• ORM Frameworks

Object-Relational Mapping (ORM) frameworks like Hibernate or JPA (Java Persistence API) simplify database interactions by mapping database tables to Java objects. These frameworks automate the tedious and error-prone task of manually writing SQL queries and handling the conversion of data between the object-oriented and relational paradigms. By utilizing Hibernate or JPA, Java developers can focus on the business logic of their applications rather than dealing with low-level database operations.

• JUnit and Mockito:

JUnit and Mockito are essential tools in the arsenal of a full stack Java developer. JUnit is a popular testing framework that enables the creation and execution of unit tests for Java applications.
