Many new Devs/Interns texted me reagrding how they can improve their Java/Spring Boot backend skillset to compete in Market. Below are the few points which I would like give them as a part of Advice as per my exeprience. It will surely land you a good package job.

1. ⁠Build enterprise level application projects , not just CRUD. I mean try to implement features like Security, Logging, Cache Management, etc. In this way you will learn practically the concepts of Spring/Spring Boot.

2. ⁠Try to learn Cloud features also by integrating it in your project apllication. For example, for saving images you can use S3 buckets. This improve your Cloud Knwoledge.

3. ⁠Learn about Messaging services like Kafka, AWS SQS queues and try inplementaing the same.

4. ⁠Instead of just writing controllers and services using Spring Boot, also focus on Spring basics. Why it introduced ? Not just theory, practical implications too.

5. ⁠Follow some youtube channel to learn important concepts like Multithreading, Collections. Inplement the same in your application.

6. ⁠Try building your apllication by learning HLD and LLD concepts. When you build your own system and implement it in real, you will encounter problems for sure. Learn how it can be solved in different ways then choose most effective way.

7. ⁠Learn about both SQL and no SQL databases. Implement them in code. Practice conplex queries.

8. ⁠Join Open source contribution discussions on respective communities.

9. ⁠Ofcourse Data Structures are must. Know them. Implement then in your code. You should have inplementation idea of inportant algorithms.

10. ⁠Last but not least learn daily. Code daily. Learn one new thing daily. Spring is very vast. If you learn one thing daily, still there will be something that you dont know.

I wrote an article on my website, Comp Sci Central answering the question:

What can I create using Java?

It gave a brief overview of what it's used for, a list of major companies that use Java in their technologies, and a list of projects for beginners to get started on. I thought the list of beginner projects might be particularly beneficial to some in this group, so here it is:

1. Simple Banking Application (This one is super easy)

2. Email Administration Application (A little harder)

3. Student Management System

4. School Management System

5. Text-Based Adventure Game (A few different games)

6. Pong Game

7. Snake Game

8. Brick-Breaker Game

9. Flappy Bird

10. ATM Interface (Like the simple banking application but much, much more complex)

Full article here: https://compscicentral.com/java-projects-for-beginners/

I didn't make any of these projects, just a disclaimer I guess. And if this is too basic for this medium, I apologize.

Take care and happy learning.

Hi all! I very often see posts in which people ask what they should learn after they complete the MOOC course or even more general questions like what they need to learn to become a java developer. I thought that it would be nice to provide a detailed answer to these questions, that's why I created this guide: https://www.devoxify.com/posts/the-definitive-guide-to-java-backend-developer-career-path/

I hope that those who still don't have a clear path will find it helpful! Any suggestions to improve this guide are very welcome!

so I’ve been trying to learn how to code in Java for about 2 months now. But it’s so difficult actually coding, like I’ll read books and watch yt videos but when I actually try coding myself, it’s so different. Please give me advice. Is this a phase ? Is it normal ?

Hey everyone!

I'm Echo, a 16-year-old student from Italy, and for the past year, I've been diving deep into machine learning and trying to understand how AIs work under the hood.

I noticed there's not much going on in the ML space for Java, and because I'm a big Java fan, I decided to build my own machine learning framework from scratch, without relying on any external math libraries.

It's called brain4j. It can achieve 95% accuracy on MNIST.

If you are interested, here is the website - https://brain4j.org

If someone outside the field tries to decide which language to learn, and looks at videos from some tech influencers, they might get the impression that Java is dying out and that it's very bad language. This was my impression when I was deciding what language to dedicate to. Now I see that Java is very much alive, and there isn't any indication that it's going to be replaced by some other language. Anyone has the same impression? Where this discrepancy stems from?

We had a small hiccup getting Part 2's exercises loaded, so we came here to look into it (it was /r/learnjava that led to mooc in the first place). The issue resolved itself, but I realized I wanted to share (I hope that's okay with the rules/mods).

He even got to the point where he could look up/work out new things on his own; he wrote a program to save/load a text file by looking things up on w3Schools. His next 'side' project is to get it to append instead of overwrite.

I'm positively beaming that he had the tenacity and wherewithal to make it all the way through Part 1 and is excited about starting Part 2!

I'm about halfway through it and it's amazing. It's 300 projects with 1 000 tasks to do.

Each makes you practice some real world skill, like I/O, String processing, concurrency or HTTP and web sockets.

Every task has a solution in the book, but obviously the point is to think about it and come up with your own, or try at least.

I’m new to Java & today I passed the MTA Java certification exam which I wanted to celebrate here!

Hello everyone,

A group of fellow CS students and I have created a platform on which we can teach people the fundamentals of a variety of programming languages for free (Python, C++, Go, HTML/CSS, Java, etc.). We have free, live programming classes through Discord at many different times for anyone around the world to join and learn, regardless of age. If you are interested in learning, here's our discord: https://discord.gg/u3XszcU and our website: http://codetheuniverse.org/. If you might like to teach a class on a programming language/topic we do not cover yet, please DM me!

EDIT: Here's a copy of a lecture of ours on Python and C++ if you kind of want to see how things work:

https://notes.codetheuniverse.org/python/lecture1.pdf

https://notes.codetheuniverse.org/cpp/lecture1.pdf

I've been days wasting my time trying to solve something easy as fuck just because I didn't use pen and paper to see things clearly. Consider this if you don't have a magic mind able to visualize Hell.

It was announced today, maybe the mod can add it to the sidebar, thanks

https://www.udemy.com/course/build-10-java-beginner-projects-from-scratch/?couponCode=2EC5A6A9B48A31406313

(It's my opinion and my experience.)

You can buy the course but come to that when you have solid beginner foundation. Don't start java from there.

Why?

Up until the concept of object he was doing OK explaining loops, data types, methods, etc. When it came to OOP, I was banging my head to the wall, trying to understand what he was saying. Spent hours on different YouTube videos after watching his tutorial on a subject.

Almost all his examples are based on initial temporary project at the beginning of the video or the one before. If you lost track in between, you must start from the beginning, otherwise you are wasting your time.

NOT A LOT OF PRACTICE to solidify a subject. After doing some of his Udemy-problems, I thought I was getting the hang of it. When it came to solving problems outside of his course, I didn't know what to do, how to do and where to start.

Starting from OOP he starts giving you twisted challenges while you still learning how to loop from 1 to 100. The way he explains the challenge, using advanced level language, adds to confusion.

So, if you are starting from 0, don't start from his course.

Hi,

I created a video tutorial demonstrating how to build an application like Reddit using Springboot and Angular. A basic understanding of Springboot and Angular is required to follow along the tutorials.

Hope this is helpful for somebody. Please don't hesitate to ask any questions about this tutorial, happy to help :)

I see a lot of these types of websites, and honestly I feel kind of overwhelmed by the amount of them. So my question to you is: What website do you prefer, and why?

I'm sure there's plenty of people wondering this.

Thanks!

When I picked up my first programming book (Head First Java) 7 years ago so I could make Android apps, I had trouble wrapping my head around for loops. I've come a long way since then, and ended up getting a CS degree, making some profitable side projects, and raising money for my startup. Recently started a YouTube channel and thought it would be fun to make a compilation of all my (mostly failed) projects from my first app to my current startup, to show the less glamorous side of software startups.

Hope you guys like it! https://youtu.be/vEvXWUUTzqU

I highly recommend this course for anyone from Beginners to Advanced in Java. It's completely free until 2021 and will take you through all the topics you need to know to get a job as a Java Developer including things you can only find in books/youtube (like Spring, JDBC, and Big O).

http://www.hyperskill.org

Here is an image of all the topics they include. It's impressive. https://imgur.com/8yzk2jZ

Edit: They also offer tracks in Frontend, Algorithms, Essentials, Python, Dev Tools, Kotlin, and Java!

Edit: OMG Thank you kind redditor! My first award!
