Hello guys, I have prepared for hundreds of interviews in my 2 decades of software engineering career but let me tell you that System design interviews were the hardest part of my interview preparation.
Not because I lacked experience, but because most resources taught what to design, not how to think. I could memorize architectures, but when the interviewer changed constraints or asked follow-up questions, I struggled to adapt.
That changed after I started using ByteByteGo.
Hello guys, cracking interviews at FAANG and other top-tier tech companies in 2026 requires more than just grinding LeetCode. Interviews today test coding fundamentals, system design depth, behavioral clarity, and communication skills — often across multiple rounds. Over the years, I’ve tried dozens of platforms, books, and mock interview tools. Some were great for algorithms, others for system design, and a few stood out for realistic interview practice.
Hello guys, I’ve spent the last 8 year systematically reading and reviewing React.js books. Not skimming them. Not cherry-picking chapters. Actually reading 30+ React books from cover to cover, taking notes, building projects from their examples, and evaluating their real-world applicability. Most React books are either outdated (written for React 15–16), overly theoretical (heavy on concepts, light on practice), or too shallow (barely scratching the surface).
Hello guys, I’ve joined and gone through 30+ SQL and database courses across every major platform in last 20 years. Not just watching — actually completing them, doing the exercises, building projects, and testing my knowledge against real-world scenarios. Most SQL courses are either too shallow (surface-level coverage that leaves you unprepared for real work) or too academic (heavy on theory, light on practical application).
Hello guys, if you are a course creator or educators and looking for a perfect place to create and host your course then you have come to the right place. The online course industry is exploding. In 2017, it was worth $170 billion. By 2026, it’s projected to reach $350+ billion. For good reason — courses are the ultimate scalable business model. You create once, sell infinitely.
But here’s the challenge: Which platform should you use to build and sell your courses?
I’ve spent the last 48 months testing and comparing 20+ course platforms including the very best ones like Teachable, Thinkific, LearnWorlds, Payhip, Udemy, Kajabi, and Podia.
Hello guys, I’ve spent the last 48 months systematically testing and evaluating 30+ websites, courses, and platforms for learning Java. Not just reviewing them — actually using them, working through lessons, solving problems, and tracking learning outcomes.
The question I wanted to answer: Which resources actually teach Java effectively in 2026?
Most beginners fail at learning to code because they spend too much time watching and not enough time doing. They don’t write enough programs. They don’t solve enough problems. They don’t develop programming logic.
After extensive testing, I’ve identified 6 exceptional resources that will take you from absolute beginner to competent Java programmer in 3–6 months with consistent effort.
Here are my top 6 websites and platforms to learn Java for 2026.
Before diving in, understand what separates great Java learning resources from mediocre ones:
Beginner-Friendly — Assume no prior programming knowledge
Hands-On Practice — Extensive coding exercises, not just theory
Interactive Learning — Code in the browser, get immediate feedback
Project-Based — Build real projects, not isolated problems
Clear Explanations — Concepts explained simply, not assumed knowledge
Progressive Difficulty — Start easy, gradually increase challenge
Community Support — Help when you get stuck
Affordable or Free — Learning shouldn’t require big investment
Modern Java — Teaching current Java versions, not legacy code
The resources below all meet these criteria.
Without any further ado, here are the top resources you can use to learn Java online, for free and for a nominal cost. Most of the site have free resources but if you need quicker and better learning, you can also buy premium resources for an affordable price.

The 80/20 Rule:
The Problem Most Beginners Face:
The Solution:
Go Free If:
Invest Money If:
My Honest Take: If learning Java could change your career (even small chance), spending $100–300 is an incredible investment. The ROI is massive if you follow through.
Learning Java in 2026 is easier than ever. You have incredible free and paid resources available. The only barrier is your willingness to put in consistent effort.
The developers who succeed aren’t smarter. They just code more.
My recommended path:
Start today. Code daily. Build projects. You’ll be amazed what 3–6 months of consistent effort can do.
P.S. — The most common reason beginners fail isn’t lack of resources. It’s lack of practice. All the courses in the world won’t help if you don’t actually write code. These five platforms all emphasize practice because that’s what actually works.
Pick one. Start today. Code something. That’s all that matters.
