One of the fundamental aspects of Spring IoC (Inversion of Control) is dependency injection. It injects objects into the other objects (also called dependencies). In other words, it allows for loose coupling of components and makes the Spring container responsible for managing components.

Dependency injection keeps the Java classes independent of each other, and the container frees them from object creation and maintenance. Dependency injection can help avoid problems like system failure in the long run by combining the application classes while maintaining their independence.

Simply put, Spring Boot is the extension of the Spring framework. It eliminates the boilerplate configurations required for setting up a Spring application. Among the most important features of Spring Boot, there are as follows:

• Opinionated ‘starter’ dependencies to help simplify the build and application configuration
• Metrics, health check, and externalised configuration
• Automatic design for Spring functionality when possible
• Embedded server to avoid complexity in application deployment

Both Spring and Spring Boot support package managing technologies like Maven and Gradle. But they differ significantly when it comes to deployment. There are certain advantages of Spring Boot in that department that include:

• Embedded container support
• Ability to run the jars independently
• Possibility to exclude dependencies to avoid potential jar conflicts
• Random port generation for integration tests
• Ability to specify active profiles when deploying

A great addition to the Spring framework features can be the Security framework. It is a practical and highly customisable authentication and data access control framework. It’s often used as a standard for Spring applications.

Various handy functions come with this framework, and the most notable include:

• Comprehensive, extensible support for authentication and authorisation
• Protection against attacks such as session fixation, clickjacking, cross-site request forgery and more
• Servlet API integration
• Optional integration with Spring Web MVC

Spring can make an ideal web framework. With features like inversion of control (IoC) and exception handling, it can fit right into your business logic.

Spring’s web framework using Spring Bean objects can contribute to building an application server and may scale up to global transactions. It integrates with various Java EE technologies such as RMI (Remote Method Invocation), AMQP (Advanced Message Queuing Protocol), and Java Web Services.

Game development

This language is equipped to develop entire games with 3D graphics, as it comes with a built-in game dev library, “pygame”. However, Python code can also create functionalities and add-ons in larger games.

Software testing

Sometimes, instead of using Python as the default language, the developers apply it for testing software and new ideas, processes and algorithms to see if they could find a place in the final product. When the idea is not yet wholly feasible, Python may be a cheap solution for testing it.

Embedded systems

External programs can test embedded systems efficiently. Writing a separate testing algorithm on a separate device (among other languages, also in Python) can simulate the algorithm on the embedded system for hassle-free testing.

Relatively low learning curve

Thanks to its intuitive syntax and large, active community, learning this language can be relatively easy.

Scalability

Python is highly scaleable, and writing code can grow with the project. Instagram, Facebook, and Pinterest are the most prominent examples of adopting it into scaleable products.

Portability

Developers can use this versatile language n different platforms and major operating systems. Python belongs to WORA (Write Once, Run Anywhere) languages. Which makes it a good multiplatform choice.
