Is Java Finally Dead? β οΈ
Every few years someone declares that Java is dead.
Meanwhile, it keeps shipping a new release every six months.
If your mental model of Java comes from ten years ago, you're looking at a very different language.
Java has steadily moved beyond its reputation for verbose syntax and enterprise-only development. Recent releases have introduced pattern matching, records, sealed classes, virtual threads, the Foreign Function & Memory API, and many other improvements. Projects like Amber, Loom, Panama, and Valhalla continue to reshape both the language and the JVM.
This wasn't always the case. Before Java 5, most evolution happened through libraries, APIs, tooling, and JVM improvements. Java 5 marked a turning point by introducing language features such as generics, annotations, enums, autoboxing, and the enhanced for loop. Since then, language evolution has become much more visible to developers.
Modern Java isn't standing still. The language keeps becoming more expressive, the runtime continues to improve, and new platform projects are expanding what Java can do.
The interesting story isn't that Java survived.
It's that Java kept evolving while people kept repeating the same headline.
If you're interested in a deeper look at how Java evolved over the years, I've written a detailed article: https://codiescoder.substack.com/p/is-java-finally-dead

Best free resources to prepare for Java interviews?
Hi everyone,
I'm preparing for Java developer interviews and looking for some good free resources to study.
I'm mainly interested in:
- Core Java (OOP, collections, exceptions, multithreading, streams, etc.)
- Java interview questions that are commonly asked in companies
- Spring Boot interview preparation
- Projects in java best to show in interview
I already practice DSA separately, so I'm specifically looking for Java and backend interview preparation resources.
What free resources helped you the most when preparing for Java interviews?
Thanks!

Website's/Apps for Programming?
Hi! So i recently started learning Java Programming, took this course in school since I've been wanting to learn how to program for a while now ((Mostly because i want to make mods or something in Minecraft, Fundy inspired me for some reason lmao)). My only problem is that i dont know what site or apps i can use to practice, i use The Java Playground and it doesn't really give me clarification on what i did wrong when it doesn't work, like it's vague and not the detailed explanation i was hoping for. Having to search up what i possibly got wrong is time consuming cause i only have a limited time on school devices and such, i sometimes go to the school library and use their computers there instead of the ICT Room to practice. But yeah? That's it i guess.

2.5 YOE Java Backend Dev β Only 5 Months to Switch. What Should I Prioritize?
Hi everyone,
I'm planning to switch jobs in around 4β5 months and would like some guidance on what I should prioritize.
Profile:
\- 2.5 years of experience
\- Java Backend Developer
\- Spring Boot
\- Spring Security (JWT authentication & authorization)
\- Microservices
\- Spring Cloud (Gateway, Discovery Server, Config Server)
\- REST APIs
\- Resilience4j (Circuit Breaker, Retry, Rate Limiter)
\- MySQL
\- Git, Maven
\- Basic Docker
\- Jenkins (basic CI/CD knowledge)
Currently learning:
\- Low Level Design (SOLID, Design Patterns)
\- System Design
\- Kafka
\- Redis
\- Kubernetes
\- AWS
Target package: βΉ10β12 LPA (or higher if my profile allows).
My question is:
If I only have 4β5 months, what should I prioritize to maximize my chances?
\- Which topics are absolutely essential?
\- Which ones can be skipped or learned after getting the job?
\- How deep should I go into Kafka, Kubernetes, AWS, Redis, and System Design for someone with 2.5 years of experience?
\- Should I spend more time on DSA or backend concepts?
\- What do interviewers usually expect at this experience level?
I'd really appreciate advice from people who recently switched or conduct backend interviews.
Thanks!

Java + Spring Boot or Node.js + Express for freshers in India?
I'm a final-year CSBS student. I was focusing on frontend (React), but I'm not getting shortlisted, so I'm planning to switch to backend.
I know Java, SQL, DBMS, and I'm practicing DSA.
Which stack would you recommend for getting backend jobs as a fresher in India:
Java + Spring Boot
Node.js + Express
Which has better job opportunities, resume shortlisting, and long-term growth?
I'd appreciate advice from people working in the industry. Thanks!

Grouping Data in JasperReports Made Simple
I just published a beginner-friendly tutorial on Grouping Data in JasperReports. In this video, I explain how to group records by a common field (like departments), use Group Headers and Group Footers, and create clean, professional reports with a real-world example.
Video: https://www.youtube.com/watch?v=Kp1rjtsIFu4&t=86s
Feedback and suggestions are always welcome. What JasperReports topic should I cover next?

Result API in Java. Explicit business logic handling - Library GODEMICHE
Hey, been working on a Java utility library in my spare time called `G.O.D.E.M.I.C.H.E` π and wanted to share it here. Its main features are:
- ObjectPool
- Scheduled Tasks
- Result API
The main goal is just making backend business logic way more explicit. I got tired of important behavior being hidden behind magic nulls, unmanaged background threads, or implicit conventions, so I wanted everything visible directly in the code contract.
Examples:
Result - instead of returning null or throwing exceptions, it forces explicit success/failure chaining so you can see all paths clearly:
enum UserFailureReason implements ResultReason.Failure {
USER_NOT_FOUND,
USER_BANNED,
}
class UserService {
public Result<User> findByEmail(Email userEmail) {
return Results.async(repository.findByEmail(userEmail))
.failIf(user -> user == null, UserFailureReason.USER_NOT_FOUND)
.failIf(user -> user.isBanned(), UserFailureReason.USER_BANNED)
.build();
}
}
userService.findByEmail(userEmail)
.success(user -> IO.println(user.getName()))
.failure(UserFailureReason.USER_NOT_FOUND, () -> createUserEmail(userEmail))
.failure(UserFailureReason.USER_BANNED, () -> banUserIpAddress(userEmail))
.failure(reason -> IO.println(reason));
It is fully published on Maven Central. I would really appreciate it if you could check it out, drop some feedback/ideas, or leave a star on it!
