It means that Java lets you write your program once, and then you can run it anywhere with the Java helper tool (called JVM). Where developers do not need to make special versions for different https://wizardsdev.com/en/vacancy/back-end-java-developer/ devices. In this article, you learned about the Java programming language’s history. You have also learned the key distinctions between Java and Node.js, clearing up any uncertainty.
Java strives to be more manageable, but it must settle for unnecessarily complex programs and detailed explanations for each thing. The compiled code (the byte code of Java) is platform-independent and can run on any machine, irrespective of the operating system. We can run this code on any machine that supports the Java Virtual Machine (JVM), as shown in the figure above.
Top AI tools for Developers, Designers and Writers – 2023
Start by describing the methods you use to ensure data integrity. For example, you can talk about how you use a combination of database constraints, such as foreign keys and unique indices, to prevent duplicate entries. You can also mention how you use encryption or hashing algorithms to secure data. Additionally, you can discuss how you set up processes for regular backups and recovery plans so that data is not lost in case of an emergency. Finally, emphasize your understanding of the importance of data integrity and your commitment to ensuring accuracy and reliability. Talk through a specific example of when you’ve integrated an API into an existing application.
Many Java programs use SQL (Structured Query Language) when building and using databases. Ideally, you should also familiarize yourself with Oracle 12c, Microsoft SQL, and MySQL database systems. In many organizations, developers receive requests to debug problems found by other team members and users – so you will be expected to liaise with others throughout the debugging process.
You need to have a good command of basic languages if you’re looking for perfect output via coding. In the field of development, language is the base and for that, you need to have a strong command of languages. This is how a backend developer is going to create a solid frame and its connectivity via servers. The desired outputs and functionality will work only if you’ve mastered the backend programming language.
This is carried across Java’s range of platforms and systems, including Java ME. The web development industry is expected to continue to grow, which consequently means that IT careers will continue to be in hot demand. This makes it very challenging to find the right backend developers. Yet, it is a challenge that any organization must overcome to deliver quality products and services successfully. Further, partnering with a software development company saves the organization time since it does not need to worry about hiring.
Backend Language #5: Python
Explain your project requirements, technical solutions, and the project technical environment in detail. Once you select a software engineer, you need to manage the hiring process. Remember that job boards don’t offer any project management support.
- Unlike SOAP, REST doesn’t require XML — you can obtain output in a language that works well for your project.
- The IoC container instantiates, manages, and assembles beans through Context and Dependency Injection (CDI).
- It was released back in 1995, also making it one of the oldest popular programming languages, which continues to receive regular updates.
- Backend developers use these APIs to establish connections between different applications to enhance user experience.
- If you feel overwhelmed, we don’t blame you—there are a lot of skills to keep track of, especially if you’re learning on your own.
It is actively maintained and open-sourced, created by the same founder of the Linux operating system. Each developer with a working copy of the code can easily access the full history of what changes have been made, making it easy to edit and restore the code. Among any back end developer skills list, Git is one of the most high-performing, flexible, and secure. If you want to familiarize yourself with the language, try an open-source platform like MySQL. Named for creator Mondy Widenius’s daughter My and offered by Oracle, MySQL provides free access to SQL database source code. It’s also reasonably easy to use, as it can be installed on desktops and servers.
Backend Programming Languages
This makes it more accessible for developers and companies from all backgrounds, as well as being suitable for individuals learning by practising. Oracle estimates that Java runs on over 15 billion devices worldwide, so it is well worth getting to grips with. According to the TIOBE index, Java is the 3rd most popular programming language. Although many competitors have challenged the market in that time, Java still has a reputation for being a crucial language for any software developer. These competencies can facilitate and speed production processes.
Since servers are the most commonly used medium to deliver important services, most servers are never turned off. This part of the servers makes it an essential element for a backend developer to learn about. Some examples of servers are Apache, Nginx, IIS servers, and Microsoft IIS. A database stores the data and site content in a way that makes it simple to recover, arrange, alter, and store information.
In the early days of the web, backend systems were rudimentary, mostly managing and serving static content. But as websites grew more interactive in the 1990s, the need for dynamic content management led to the rise of server-side scripting languages like CGI scripts written in Perl. Java entered the scene and introduced Servlets, providing a way to generate dynamic content. Then came the Enterprise JavaBeans (EJB) for business logic and JavaServer Pages (JSP) for dynamic web content and to handle lively web content. Today’s backend methodologies extensively address aspects like APIs, microservices, deployments in the cloud, and seamless coordination with a multitude of third-party services. In this overview, I hope you were able to get a clearer picture of backend development and the capabilities of each language included.
And it depends on the developer as to which language he/she feels comfortable. However, some languages are preferred over others due to the ease of use and the community background behind them. Backend developers are the troubleshooters of the digital world. Cultivate your problem-solving abilities to navigate challenges seamlessly. Your role involves keeping websites running smoothly and making strong problem-solving skills an indispensable asset. As such, back end developers would do well to have both skills in their repertoire.
