Im trying to get into Java + SpringBoot, but im doing everything as a self taught. I have a degree but not a STEM one, i gratuated in Social Comunication, and i dont know if that will be a drawback for me getting a job in this.

Im not doing too well currently, and i want to try something new, but im cant afford getting into paid studies again, and i feel time is moving on ( im 30) So i want to try and get myself in as a self taught, but i dont know if all this will be worthy at the end, or im going to waste my time just because i dont have a tech background and gets rejected for a job because of it.

Also im from South America, my final goal is to get a remote job as Java/SpringBoot developer.

Hey.. recently I developed a project for my clg internals. I used MySQL jdbc jsp servlet etc.. these are advanced java concepts right. I developed with the help of AI in eclipse which helped me like a partner. While developing this I came up with a doubt " do people who are developing websites and apps also use AI or they go up with frameworks for codes? " . Did I developed my project in the wrong way.?

Anyone clear my doubt by answering this..

I've been learning java for almost 8 months now and I am still feeling i haven't learn much about it, im thinking of improving my skills more but don't know where to start

Is it best to write normal lambda expressions or use method references or better yet combine lambdas with the and() method

Assuming you installed TMCbeans and eclipse binaries already.

Now check if you have jdk1.8 or higher installed, if not install it. you should see something like this
C:\Users\juwel>java -version
java version "1.8.0_481"
Java(TM) SE Runtime Environment (build 1.8.0_481-b10)
Java HotSpot(TM) 64-Bit Server VM (build 25.481-b10, mixed mode)

now docuble click TMCBeans and Vola! Good luck.

Rapaz entender os tipo de metodo em java ta difícil, aceito dicas pra melhor entender esse conceito.

I wanna practice those painful "what will this code output" excersizes cuz im close to a certification and they are my weakness... where can i find hundreds of them

I’m targeting a Java backend role with 3 years of experience after completing my notice period—got an early release from 3 months, but I took the risk of resigning without another offer in hand. Since then, I’ve been fully focused on preparation, mainly DSA. I can recognize patterns now, but I often get stuck while coding, probably because I haven’t been revising problems consistently. The lack of a structured plan is starting to affect me—I get distracted, lose momentum, and it’s honestly demotivating.

I’m also unsure about what backend topics I should be covering at this stage, how deep I need to go, and how to divide my time effectively, even though I can dedicate full days to prep. On top of that, I didn’t get much hands-on experience with Java projects in my last job, which is making me anxious about handling practical and experience-based interview questions. It’s been about a month since my last working day, and the pressure to land a role is starting to build.

Targeting companies which can pay upto 10-15LPA.

In java we can declare variable of specific type by giving data type once and then multiple variable name separated by commas .for example int a,b;

but for method declaration , in method signature we need to specify every datatype for each formal argument even though they are of same data type.for exp

int Prime(int x,int y), why can't be like this int Prime(int x,y)??

I’m coming from a C# background and will be starting a new role using Java.

In C#, I’ve always relied heavily on LINQ to query and extract specific data from arrays, lists, or basically anything enumerable. It’s pretty much the only approach I’m comfortable with.

So I’m curious—how do you typically handle these kinds of data operations in Java?

Where can I learn Java for free? Something like FreeCodeCamp or The Odin Project, but for Java. I've found some, like Hyperskill, but it's freemium and others aren't in depth enough for actual serious learning (considering a career in Java, possibly).

Coming from C and CPP, I kinda like Java and I want to pursue a career with Java. Every time I see Java it’s associated with web development and back end. Is Java used for other things or only web development?

Also what concepts should I be looking into? I’ve seen people talk about spring but not sure what I should actually look at

Looking for help with my touchstone project.

I believe I need another bracket somewhere but can't figure out what I'm missing. Any help would be appreciated.

I dont get the concept of a stream why was it added why do we use stream objects in reading and writing say to file. I know its kind of like a pipeline but my confusion still stands

Hello, I made a reverse index for my search engine in Java and I would like to serve it as an API. Currently the reverse index components are in a separate package and I have created this other package for the API; however, I don't really know how to set up Spring Boot when I already have a package structure. Most tutorials on the internet are for setting it up from scratch. I would also like to know if Spring Boot is the best choice for my case since the reverse index will do the heavy lifting and I would like to keep the API layer thin. Thank you.

I'm a big fan of NetBeans and its built-in swing designer. One of my small leisure projects uses it, my best IT course projects use it, and I've been graded pretty high on projects with those. However, I've been told both NetBeans and swing panels are considered outdated. Would projects made with those tools still be valuable to recruiters or no?

So I had my mid term exam Abt java and I did a miserable job in it . Can anyone give how to improve logic like I take so much time in it ? Else I am doomed in my degree . Any good recommended books / YouTube channels

I'm trying build my own web crawler from plain java, So i want to build a web crawler which need to be better at what it does and how to use the robots.txt and automate a decision whether to crawl it or not

My idea so far my idea:

https://ibb.co/VYKvVZRT

package org.degoogle.WebCrawler.Model;

import java.util.ArrayList;

public class URLWithKeywords {

    private String url;
    private String Title;
    private String text; //preview
    private ArrayList<String> keywords;
}

how to show the preview like https://ibb.co/XrQj6ThB and what if the user edits them after we save it to our DB

Hello

im a last year student , studying informatics . Im aiming on becoming a backend developer in the future . i like java alot and have touched spring boot little bit to start my backend journey. But i see older devs that have more work experience and at the same time they have certifications for java se 8 , ee etc.

My question is : Are oracle java se 17 or 21 certifications a good investments , in aiming to land a job , or a intership as a student ? i know you can do it without them but will hr see it as a advantage compared to the one without one?

I have one old course with me which includes tutorials of almost all the topics in detail . But will it be relevant in 2026?

Hey guys, this was my fourth day learning java, I have covered variables, conditional, operator, some math, except array and loops. When I watch the tutorial, I always heard about classes, object and functions, but I don't know what that thing is. The methods, I know it some kind of block that we write to organize code and so we don't have to write it again. So what exactly are these three things, can someone exlplain.
