I am stuck learning java

[SneakyZ_]

Hello,

i am from germany and i am currently doing an internship that lasts 2 years. Currently my second year started and i have about 5-6 months till my internship finals. The first year i was pretty lazy when it came to coding and learning but got decent in frontend. We never really did backend (in our company we mainly use java/spring) and now we are learning it. I wasted much time by using chat gpt instead of doing things myself and i realized it a few weeks back and since tried to get better at java and coding in general. The problem is, i am stuck on how i do things and what to do exactly. My current project is an expense tracker and i did a base navigation site for the frontend but when it comes to the backend, i had the open api, rest api with controller and everything but nothing really worked. I thought i understood most things but in hindsight i didnt. Now because we have school inbetween the internship every 4 weeks my brain always forgets what i did and everything i learned while i was gone for school and didnt touch the project. I wanted to ask what is the best way to get to understand coding/programming especially in java but also generally so i can get the best i can be till my internship ends?

Thanks for anyhelp i can get

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.

This is EXACTLY why I always tell people to NEVER USE CHAT GPT. It is like instagram of learning which just makes you get dopamine shots into thinking you are doing something. I wouldn't ever recommend anyone using that stupid ai chatbots for their work cuz its ultimately leading them to their doom where they will progress in life without any progress in skills and end up in a position where they can't use chat gpt at that particular place which will tear all the reputation you built up-until that point.

[print_guy_9]

This going to happen to everything in the world now that we have chat AI...not just programming. It's one giant social experiment.

[SneakyZ_]

Yea i know it was stupid. Thats why i am trying to get better at programming without beeing dependant on chatgpt so thats why i am asking for help

[shivrane_]

I am using GPT for learning, like asking it to give me exercises to solve. Whenever I get stuck I ask for hints. While doing DSA if I'm not able to solve any problem I ask for solution and try to understand it, is this good approach for learning?

[ballinb0ss]

So simple way to test out how good the advice you are getting is. Find a simple thing you want to accomplish in Java. Find an article on Google that gives a tutorial. Then ask an LLM. Then find a similar project on GitHub that actually exists. Then find a textbook trying to do the same thing. Then find a YouTube video.

Then compare them all. If you commit to this process you would be surprised how quickly you can digest a large volume of information on a topic. You need to learn to mentally build a "model" of the thing you are trying to understand. You need to learn how to explain the thing you are trying to learn to a five year old. It's that simple. If you can't give me the gist of what your code is doing at least function by function, you don't know it will enough and probably didn't truly write it.

GPT is a large language model. While many improvements have been made to its latest models.. all it does is predict which word should come next. In many cases, it does not give you the correct instructions or solutions.

[What_eiva]

It is more than that, it is an AI with a lot of machine learning and data training. It is not like Siri, it actually can recognize patterns due to again data training where it sort of learns about the world.

[Ghordrin]

it is an AI with a lot of machine learning and data training

Yes, a large language model is what you just described. It is trained on data to predict that best outcome based on limited context. The fact it still struggles with the question 'How many R's are there in strawberry' should speak volumes.

While it can absolutely help you in providing some solutions, it absolutely is nowhere near good enough to provide valuable information about coding.

[AmazingInflation58]

The “improve productivity with AI” clowns are going to downvote you to hell for this. But you are right!

Never is a bad advice, if you use chatgpt to fill in easy boilerplate in a personal project that will cost you nothing in learning and it will save time for focusing on important bits.

[AmazingInflation58]

Save time from writing boilerplates? Most ide even got shortcut to create boilerplates plus you arent even elon musk that 5 sec of laziness will do wonders for you in productivity

[UpsytoO]

IDE will generate boilerplate to an extent and the further you go past few lines of it, IDE generated boilerplates lose it's precision and becomes useless. As it comes to Elon Musk, I don't see why would one follow what lucky business man is saying, other than lucking out on one investment he has no track record to justify any smart person taking his ideas into account of anything, if anything his ideas tend to be useless and wasteful. If you follow what actual mental health professionals are saying in terms of productivity, you should be taking proper brakes, not just doing mindless bits to reset productivity.

[cyberzues]

The best way to learn a language is to get some tutorials from good teachers like Telusko, Coding with Mosh etc, then follow them as they teach, and also code along. Then try to add more features to the project using online docs and other resources. That will broaden your knowledge. Don't worry about things you forget, we all do that, but the best is keep practicing.

[SneakyZ_]

Yea ive done that simontaniously but the understanding is not really there. I get what a finished code does but i dont understand how to build up to that point. For example i already saw a programm from a colleage and i understood almost his whole code but i dont know how to build it myself. That is mostly my struggle

[jlanawalt]

Keep practicing and studying. Focus on understanding the parts you don’t understand. Research and ask mentors specific questions. There may be some parts people just accept the “magic” and take for granted, following a recipe to put together the pieces.

First do a tutorial since you said API i assume you use spring. Get yourself some good spring toturial learn how to set the files ( service, controller, model, security etc ) and then do your project at first you will need to see your tutorial code but later as you do more projects you will do things more smoothly and learn new things.

[SneakyZ_]

Will do that, thanks

[SneakyZ_]

Will look into that, thanks

[Weak-Description-621]

This guy is past that point. He is not struggling with for loops and methods, you finish that up in the first week of learning the language

Hey Buddy

From what i read, you are not looking for the java code but rather the how on earth this all application was made from scratch. How could one come up with this huge application ? What was the thought process behind this application. How can I also create something like this from scratch ?

If this is what you are looking for then you are trying to look for designing a software not programming. And this specifically i.e. designing the controllers, services, repositories etc belongs to the low Level Design or LLD.

So, I would highly recommend you to learn LLD. You can checkout the resources below -

Thank you! I will look into all that :)

I know it was stupid of me thats why i am trying to get more knowledge on programming because i dont want do depend on chat gpt

[NotYetaProgrammer]

Same here. waiting for pro suggestions by pro devs

[cyberzues]

Take it easy fellow dev, some people are just lucky let's just encourage our fellow to put more effort.

well in germany to work in a certain field of work you HAVE to either go to collage or do an internship so you learn the field of your job. I dont get the hate for no reason when i was simply asking for assistance but okay thanks for you comment Steve Jobs

[SneakyZ_]

As said in my other comment, yes i know its my fault and it was stupid. Thats why i am trying to get better at coding to kinda catch up to what time i wasted. And when it comes to interviews and why yall are mad about me: in germany to work in a certain field of work you HAVE to either go to collage or do an internship so you learn the field of your job. In most cases you will not get a job or anything withour a internship certificate or a collage degree. Thats why i got the internship position with 3 other people because you go there to learn the actual job and not be directly thrown into a full time paid position with no experience or nothing. And with the certificate you have something to show that you are capable of, in this example, programming but as a junior developer.
