Java has remained one of the most commonly chosen programming languages for building backend applications for years. Despite growing competition from languages such as JavaScript (Node.js), Python, and Go, Java continues to dominate many large systems and applications. What makes it still the king of the backend in 2025? 1. Stability and Maturity of the…
Many entrepreneurs wonder how much it costs to develop a mobile application. The answer is not straightforward, as the price depends on several factors — the scope of features, technologies used, collaboration model with developers, and the complexity of the project. In this article, we’ll present the key aspects that affect the cost of a…
Not every app works flawlessly on new flagship smartphones. Many people still use older devices with limited computing power, less RAM, and outdated operating systems. So how can you optimize a mobile app to run smoothly even on lower-end phones? Here are the key techniques worth implementing. In today’s world, where the number of users…
In the world of programming, time is money. Every minute spent writing boilerplate code, debugging, or hunting down errors in documentation is time that could be used to build innovative solutions. Fortunately, thanks to the advancement of artificial intelligence, developers have gained powerful assistants that automate routine tasks, suggest optimal solutions, and even write code…
The Spring Framework is one of the most popular tools for building Java applications. When developing web applications, it’s common to pass data between the client and the server. Two frequently used mechanisms for this in Spring are the @ModelAttribute and @RequestParam annotations. Although they may seem similar, they differ in both usage and behavior….
Unit tests are short, automated tests that verify the behavior of individual modules, or “units” of code. These units can be functions, methods, or classes. Each test checks whether a given function behaves as expected—for example, by confirming it returns the correct result for a specific input. Example of a Unit Test Let’s say we…
The Mockito framework is one of the most popular testing tools in Java, especially useful for creating unit tests. One of the most important tasks in testing is simulating the behavior of objects to check how the code under test reacts to them. Mockito allows you to do this by stubbing methods using thenReturn and…
