Introduction Records are a new feature in Java 14. We can use them to avoid a lot of boilerplate code in standard DTO classes, save our time, and limit space for errors. In this tutorial, we will show what records are and how we can use them in our code to make it more readable […]Continue reading
When you start a Spring application, the Spring Framework creates beans for you. These Spring beans can be application beans that you have defined or beans that are part of the framework. When the Spring Framework creates a bean, it associates a scope with the bean. A scope defines the runtime context within which the […]Continue reading
Introduction SDKMAN is a command line utility we can use to make managing our development environments easier. By using SDKMAN we can easily install, update, or switch to specific versions of popular tools such as the Java JDK, Maven, Gradle, and Groovy. In this tutorial, we will learn how to set up our Java development […]Continue reading
Introduction Programmers spend a great deal of time looking for errors in code. This process is called debugging and in this post, we will focus on how it is done in IntelliJ IDEA Java IDE. After reading this tutorial you should be able to find errors in code with less effort, thanks to the use […]Continue reading

Project Lombok is a Java library tool that generates code for minimizing boilerplate code. The library replaces boilerplate code with easy-to-use annotations. For example, by adding a couple of annotations, you can get rid of a lot of cerimonial code, such as getters and setters methods, constructors, hashcode, equals, and toString methods, and so on. […]Continue reading
Introduction In this post, we are going to write about Project Lombok, a must-have tool for every Spring programmer. Lombok is a Java library, that enhances programmer productivity, by providing several helpful annotations. It makes classes shorter and frees programmers from writing much boilerplate code. After reading this tutorial, we will be able to setup […]Continue reading
The Spring IoC (Inversion of Control) container manages Spring beans. A “Spring bean” is just a Spring managed instantiation of a Java class. The Spring IoC container is responsible for instantiating, initializing, and wiring beans. The container also manages the life cycle of beans. Spring provides several ways through which you can tap into the […]Continue reading
Enterprise Spring applications typically need to run in multiple environments. For example, development, testing, staging, and production. Each such environment has its own set of settings. For example, you might be using an embedded H2 database for development but an enterprise-grade Oracle or MySQL database for production. So the data source and connection configurations for […]Continue reading
