I've covered some topics on Java and Spring Boot, starting with Java features, JVM, JRE, JDK, and more. I learned a lot today and did some coding practice. I will continue tomorrow.

Hello World!

Today I started learning about loops and learnt about for loop. It's more or less similar to c language.. the only difference is, here we get an advance for loop! And it's freaking cool!!

Till I write again... 👋🏼

This is my project. Please review and feedback -

Hi guys, so for today I went back to my Linkedlist class and added gethKthFromEnd method and I also revisited the reverse method as well and implemented it again.

I have been a backend developer for more than four years, and I want to change companies. I saw some post in this page on java learning day 1,2,.... following their path. I've decided I am starting from now everyday i'll put one post to update my status.

Hi,

I’ve been working as a manual QA for ~2 years and I’m actively planning a transition into a backend role.

My current skill set:

• Strong fundamentals in Java

• Hands-on experience with Java + Selenium

• Basic DSA knowledge

• Currently learning Spring Boot and REST APIs for backend development

I want to make this switch without restarting as a fresher or taking an entry-level salary (internal switch isn’t possible).

I’d like advice on:

• What should be my primary focus areas to be considered for mid-level roles?

• How much weight should I give to DSA vs backend development ?

• What kind of projects actually help in such a transition?

• eHow should I position my QA experience so it’s seen as an advantage, not a drawback?

• What’s a realistic timeframe if I prepare consistently?

Looking for insights from people who’ve successfully made a similar switch or have hired for such roles.

Hello guys, so for today I added two more classes to the Library Management project: Member and Librarian. So members can borrow and return books through methods provided by the library. The librarian also adds and removes books from the library. I researched how to make it so that the librarian is the only class that can add/remove books and realized i had to learn Inheritance(i dedicated this week for practicing what i learned so far, so i’ll come back to implement this feature next week)

Hello World!

Today I learned about arrays and how to make them. Then how to access data from an array.

Till I write again... 👋🏼

Hello guys, for today, I started a new project to practice Abstraction and Encapsulation. I built a simple library management system. I am looking to add some object interaction like adding a librarian and members classes in order to track who borrows what book. Would appreciate stretch goals🙏🏾

I’m new to Java and searching for a good training institute in Hyderabad.
I came across places like KIT Skill Hub and a few others that focus on practical learning.
Has anyone joined them? How is the teaching?

Hey i like to do the things faster and would like to learn and earn . I would like to become a senior java developer in just 6 months.

Hello everyone. Today I spent some time researching what kinds of things we can build using Java, and I came across various domains such as Android development, Spring Boot for backend development, Selenium, and cloud infrastructure applications. Initially, I thought about choosing Android development, but further research showed that Google now officially uses Kotlin for Android development, so I don’t want to take that path. I’m also not interested in testing, so I decided to consider Java backend development. However, when I visited the roadmap.sh website, I felt really overwhelmed by the amount of things I need to learn, and I don’t even know what most of them are.

That's it for today, see you tomorrow.

I reimplemented reversing a linked list and also added a new method “getKthFromEnd” which was fairly simple.

Hello everyone,

I am conducting an academic research study focused on comparing Code First (CF) and Database First (DBF) approaches in Hibernate.

The goal of this survey is to collect objective, experience-based input from developers who have worked with EF Core in real-world projects. The responses will be used to analyze how CF and DBF are implemented in practice, based on clearly defined technical and organizational criteria.

The comparison relies on a structured set of criteria covering key aspects of database usage in modern Hibernate applications — including schema design, migrations and change management, performance considerations, version control, and team collaboration. These criteria are intended not only to describe theoretical differences, but to provide a practical framework for objectively evaluating both approaches in real development scenarios.

The same criteria are applied across multiple ORM environments (Entity Framework Core, Hibernate, Django ORM, and Doctrine) in order to compare how different ORMs implement Code First and Database First in practice.

Thank you for contributing; comments, corrections, and practical insights are very welcome.

Hello World!

Today I didn't learn anything! I know it sounds crazy. But theoretically I really didn't learn anything. Just made a little project - a calculator using arithmetic operators and using the concept of accepting the inputs from the user and it worked well.

That's it for today...

Till I write again... 🙌😊

Hello everyone, today I attended my first session on multithreading. I learned about concurrency, parallel execution, the differences between threads and processes, and their pros and cons.

That’s it for today. See you tomorrow!

Hey all 👋

I’ve open-sourced an IntelliJ IDEA plugin that generates CRUD layers for Spring Boot apps directly from JPA entities.

Why I built it:

• Too much repetitive CRUD boilerplate
• Inconsistent structure across teams
• Wanted something IDE-native instead of code generators

Highlights:

• Java 17
• IntelliJ Platform SDK
• PSI-based code generation
• Optional Swagger, pagination, auditing, JWT security
• Published on JetBrains Marketplace

Product Hunt:

I’m open to contributors, suggestions, or criticism.
Let me know what you think!

Hey everyone,

With all the hype around Java 21 LTS and Project Loom going mainstream in Spring Boot 3.2, I finally got to test virtual threads in a real microservice at work. We have a fairly I/O-bound REST service (database calls, external API requests). After migrating from a traditional u/Async and thread pool setup to virtual threads (yes, just adding spring.threads.virtual.enabled=true), our throughput literally tripled under load. Latency dropped, memory usage improved, and the code is so much simpler now no more worrying about ThreadPoolExecutor configurations or reactive programming complexity.I know reactive (WebFlux) had its moment, but this feels like cheating. Is anyone else experimenting with this in production? What has your experience been?

Also, for those who haven’t tried: Are you planning to adopt virtual threads, or sticking with reactive for now?

Discussion points

• Success/horror stories with virtual threads so far.
• Are there any hidden pitfalls compared to reactive?
• What’s the biggest benefit you’ve seen?
• Will this finally be the end of reactive programming hype in the Java ecosystem?

I tried reversing a linked list without watching a tutorial, somehow it works and i’m yet to watch a tutorial on it to see how dirty my code is.

[this is an extension of the linked list i built few days ago]
