If you’ve worked with Java backend development for a while, you’ve probably heard the term microservices. You may have also heard developers talk about things like: At first, microservices can sound much more complicated than they really are. The basic idea is actually quite simple: Instead of building one large application, you split it into […]
Security is one of the most important parts of any backend application. Imagine you’ve built a Java application where users can: You probably don’t want every user to access every part of the application. For example: This is where Spring Security comes in. Spring Security is a powerful security framework commonly used with Spring and […]
When building a Java application that needs a database, you’ll eventually come across two popular options: JDBC and Hibernate. Both can help your Java application communicate with a relational database, but they work in very different ways. With JDBC, you work much closer to the database by writing SQL and handling objects such as Connection, […]
Most real-world applications need a database. A shopping application needs to store products and orders. A banking application needs to store accounts and transactions. Even a simple user-management application needs somewhere to save user information. But how does a Java application actually communicate with a database? That’s where JDBC comes in. JDBC (Java Database Connectivity) […]
If you’re learning Java, you’ve probably heard people talk about Heap, Stack, and Garbage Collection. At first, these terms can feel a little confusing. You might wonder: Where are Java objects actually stored? What happens when an object is no longer needed? Who frees memory in Java? And why does Java sometimes pause to perform […]
If you are starting your journey with Kotlin programming, one of the first things you need to do is set up a Kotlin development environment. Kotlin is a modern programming language developed by JetBrains and is widely used for Android development, backend development, desktop applications, web development, and Kotlin Multiplatform projects. The good news is […]
If you’re learning Java backend development, one of the first things you’ll probably want to build is a REST API. REST APIs are everywhere. Web applications use them. Mobile apps use them. Frontend frameworks like React and Angular use them. Even different backend services often communicate with each other through APIs. The good news is […]
Kotlin Null Safety is one of the most important features of the Kotlin programming language. It is designed to help developers avoid one of the most common problems in application development: null-related errors. If you have worked with Java or another programming language, you may have encountered an error such as: A null pointer error […]
If you’re learning Java backend development, Spring Boot is one of the most important technologies you’ll come across. Maybe you’ve already seen code like this: But what does all of this actually mean? And why do Java developers use Spring Boot instead of building everything from scratch? Don’t worry. In this beginner-friendly guide, we’ll start […]
