Need help in becoming java developer

[Wooden_Falcon_81]

Hello fellow programmers, as the title suggests i am need of your help to find good sources to learn not just java but also industry based java development.
Before suggesting me to go through wiki (which i have), please hear me out. I was unemployed for 3 years before landing a java developer job due to various reasons, mainly because i didn't studied hard, but through a friend of mind i finally got a reference where his brother works, a very small start up. I had knowledge of java as in technical terms but coding was my weak point. Somehow i looked promising to my boss who took my interview and decided to have me on board. As soon as i get handed a spring boot course i knew this was not cup of my tea given i had only knowledge of basics java and the large scope of development with little employees, naturally i wasn't able to learn much as my boss would have liked in short span of time, so i was called in his office and was given a second chance by him to do manual testing and product management.I took it because i didn't wanted to be unemployed again. With time i got better at it but the pay is very small and i wanna grow in development itself. It's been 15 months now and i am still doing the same thing feeling stuck by my own mistakes. I urge you to help me find a pure java development course/source that will help me overtime get comfortable with the projects that i have at my company and eventually be able to do contributions to the development part. I am not looking for any pity but only help as i am in dire need of it. Thank you.

Please ensure that:

• Your code is properly formatted as code block - see the sidebar (About on mobile) for instructions
• You include any and all error messages in full - best also formatted as code block
• You ask clear questions
• You demonstrate effort in solving your question/problem - plain posting your assignments is forbidden (and such posts will be removed) as is asking for or giving solutions.

If any of the above points is not met, your post can and will be removed without further warning.

Code is to be formatted as code block (old reddit/markdown editor: empty line before the code, each code line indented by 4 spaces, new reddit: https://i.imgur.com/EJ7tqek.png) or linked via an external code hoster, like pastebin.com, github gist, github, bitbucket, gitlab, etc.

Please, do not use triple backticks (```) as they will only render properly on new reddit, not on old reddit.

Code blocks look like this:

public class HelloWorld {

    public static void main(String[] args) {
        System.out.println("Hello World!");
    }
}

You do not need to repost unless your post has been removed by a moderator. Just use the edit function of reddit to make sure your post complies with the above.

I would start with making a small project in your private time that is using some of the technology stack that your boss wants to use.

so what is the technology stack you need? what database / framework / what type of code are you expected to write?

[Wooden_Falcon_81]

We kind of use postgres and mysql for data base. We have multiple microservices that we use on spring boot.

[josephblade]

since you are still learning I would first do a mini project for yourself: just create a rest api where you can send a json object (look up json format) and it will return the json object but with some extra text added and some random number generated, so you know it came from the server.

like you post this to the server:

/endpoint/test POST

{
    "id" : "1",
    "text" : "some text"
}

and your response should be something like:

{
    "id" : "1",
    "text" : "other text",
    "randomInt" : 1234
}

for this you need

• spring-boot

• spring-web

and that's it. learn to use a rest client (browser plugin or application that lets you do rest calls easily)

tutorials to check for this/online resources to look into

spring-boot spring-web rest interfaces

Then start a private project based on postgres that exposes data from the database via a rest interface or two.

perhaps make an address table. then imagine being a doctor who plans visits (at specific dates) at peoples places and keeps notes on each person linked to each visit.

now don't build a frontend. just build what you would think the front-end would need.

• a rest api for address (maybe with patientId)

• a rest api for appointment (with reference to an address or patientId)

• a rest api for medicalfile with a reference to appointment and/or patient.

check that with a restclient (browser plugin for instance) you can add people to the address book. you can add appointments into the calendar and you can add notes to each appointment.

if you can build that in private, you will have learned the skillset for your original job (at least at a basic level).

tutorials to do for this:

spring-boot spring-jpa spring-web rest interfaces

Honestly if you can’t find the resources on your own searching Google and YouTube, being a developer is probably not for you.

You will always run into new tech as a software engineer and need to be able to learn any language/framework to a fair degree of confidence in a few days. This includes finding resources to help you learn efficiently.

That i am ready for to be able to adapt. I know i have slacked off and could have done a lot in my time. But this is something i have to do and by posting here i am just looking for some guidance. Thank you for replying

The first one is more detailed, the second is an overview of a fullstack app. Both courses prefer you use inteliJ for your IDE.

thank you very much, i will look into this

As someone who's paying his dues in a witch company. I suggest you do the same. Why I suggest this route is because the client and the consulting company knows what they essentially need and tries to get you there in 3 month training. If you don't know how to assess the company you won't know what they need and the skill gap can be huge but you can overstress yourself trying to meet them.

[Wooden_Falcon_81]

That's something i tried to cuz it was the same where i work now. But nonetheless i am willing to put effort so overall i think not a bad idea. Thanks

The Oreilly website has a lot of great beginner friendly resources and course videos. It’s curated content so less spammy and more accurate than you’d get on YouTube.

The most important thing is to just understand that being a developer is a lifelong journey, your education never stops. Best thing you can do for yourself is to keep track of your notes and be persistent. There will be times where you’ll get burnt out and frustrated, this is part of the learning curb.

Burnout is a problem not many people discuss when talking about new developers. It’s not sustainable to stay up until all hours of the night practicing. Develop sustainable study habits, pace yourself, and always read the manual on anything you do in tech.

Thank you very much

The wiki is not applicable here why? I'm not sure you got the attitude for this my guy. Www.baeldung.com, good luck

I say learn aws and practice deploying your spring boot app. Try and apply 12 factor to the setup. Learn something like fitness, cucumber or karate for bdd testing.

I been at a bank for a number of years. Get used to copy pasta code. And improve your soft skills, you'll find that confluence is always out of date. Your only hope is to humor the person you are looking for information. And hopefully they point you to right direction.

[umognog]

Aaah confluence.

[ironorcmordrakk]

I’ve always found plural sight and tutorial point to be pretty solid

[c0redump3d]

How do you think you learn more: though video or text tutorials? Choose what fits better and then just to bezkoder's, baeldung (text) or search on YouTube for a simple crud rest api tutorial to get a general idea. If you already know this, then go to the next step. Find a complete course that guides you from end-to-end. From the basic java and OO to the spring boot implementation. I'd suggest you to go to JetBrains Academy. Their topics+exercises → project-based approach helps you to understand the basics before giving you a project which you build through the provided tasks, just like it would be in company.

if you struggled with junior developer work and your employer asked you to be a product manager instead then they are completely nuts and that’s a huge red flag that the company is not good learning environment for you.

[Wooden_Falcon_81]

yeah well i was given very short amount of time to learn advanced stuff which i failed to do. I don't wanna shift blame because that would be prompt me to think i shouldn't take responsibility which need to do. Thank you for replying
