Few months ago I asked on Twitter “why you think Java is complex?” to understand others perspective. I'm really surprised looking at so many people assuming #Java is complex than other languages. I worked with mostly Java and in recent years I worked with Go, NodeJS too. But I feel Java is less complex and more productive. Any specific points why you think Java is complex? — Siva (@sivalabs) April 1, 2022 And, I got many responses(opinions, insights) and I compiled all the responses into this blog post My attempt to understand why people perceive Java as complex.

First of all, Wish you a very happy new year and I hope this year will bring more joy and happiness into your lives. I would like to share how was 2022 for me and what my plans are for 2023. Highlights of 2022 The year 2022 is very eventful for me and lots of interesting things happened. 1. “How to Become a Software Architect” series with in28minutes and JavaBrains I collaborated with in28minutes Ranga and JavaBrains Koushik and did a “How to Become a Software Architect” series

Spring Framework 6 implemented the Problem Details for HTTP APIs specification, RFC 7807. In this article we will learn how to handle exceptions in SpringBoot 3 REST API(which uses Spring Framework 6) and provide error responses using ProblemDetails API. We are going to reuse the SpringBoot 3 sample application spring-boot-jpa-crud-demo which we used for Using Java Records with Spring Boot 3 article. Assume we have the following REST API endpoints to create a bookmark and fetch a bookmark by id.

Records were introduced in Java 14 as a preview feature and became a standard feature with JDK 16. Records are a concise representation of immutable data class. Prior to Records this is how we usually create an immutable class. import java.util.Objects; class Person { private final Long id; private final String name; public Person(Long id, String name) { this.id = id; this.name = name; } public Long getId() { return this.

TLDR; I am happy to announce that I am going to create “SpringBoot Tips Video Series” on my SivaLabs YouTube Channel. This “SpringBoot Tips Series” is to help people who are new to SpringBoot to learn how to use SpringBoot with a keen focus on understanding how it works behind the scenes. Longer version I have been working with SpringBoot for several years, and I have written couple of books on it too.

I work as an Architect/TechLead/SeniorDeveloper depending on client engagement. And, Java is the primary programming language that I have used most of my career. In recent years I got an opportunity to work with Go, NodeJS and .Net Core technologies too. I find Java, especially with SpringBoot, a solid platform to build enterprise grade applications. Occasionally there comes a discussion of technology selection, and I noticed some people don’t prefer/like Java.

Java is and has been the primary programming language I have used throughout my career. If I want to build something quick for a prototype or if I need to pick the tech stack with a tight deadline then Java is my first choice. Especially after Java 8 it becomes more and more feature rich and powerful. On top of it with frameworks like SpringBoot, Quarkus and Micronaut building enterprise grade applications becomes a breeze.

In the previous article Kubernetes - Blue/Green Deployments we have learned how to release a new version of application using Blue/Green Deployments strategy. 1. Getting Started with Kubernetes 2. Kubernetes - Releasing a new version of the application using Deployment Rolling Updates 3. Kubernetes - Blue/Green Deployments 4. Kubernetes - Exposing Services to outside of Cluster using Ingress In this article, we are going to learn how to use Ingress to expose HTTP and HTTPS routes from outside the cluster to services within the cluster.

In the previous article Kubernetes - Releasing a new version of the application using Deployment Rolling Updates we have learned how to release a new version of application using Deployment Rolling Updates and how to use Readiness and Liveness probes to route traffic to only fully initialized containers. 1.

In the previous article Getting Started with Kubernetes we have learned how to deploy a SpringBoot application on Kubernetes(Minikube) using Deployment and Service primitives. We also looked at how to access our application using NodePort on Minikube IP address. 1. Getting Started with Kubernetes 2.
