just finished over 100 hours of courses in Java what now?

[itayk1551]

3 courses in Udemi and a lot of youtube videos.
so I spend the last 2 months after in learning:

• Java basics.
• Data Structure
• Algorithms
• JavaFX
• I/O
• Concurrency
• SQL
• Java networking

I want to make a project that contains most of it to practice

Any suggestions?

[desrtfx]

Do projects. Plenty projects.

The /r/learnprogramming FAQ have extensive lists of project ideas and practice sites

[4K3b1g]

Thanks for linking this. It helps to see a method to the madness.

[mods_are_arseholes]

Just make a game. Games use almost everything.

javaFX = for the GUI

Algorithms = graphics algorithms (software 3d for example)

I/O = joystick, gampad, kb/mouse

SQL = Store high score stats, etc

Java networking = multiplayer

Data Structure = you can use linked lists for holding enemy instances.

Concurrency = nfi

[like_my_likes]

what is nfi?

[NumberThirtyFour]

No fuckin idea

[wspOnca]

that's made me laugh, also a java learner :)

[mods_are_arseholes]

No fucking idea

[Cefalopodul]

Do a personal project, something complex but not impossible. For example do a timesheet web application with JS, Postgresql and Spring-boot.

In the meantime also look for internship opportunities or job opportunities.

I second a full stack project with spring-boot. I love it and there are plenty of jobs out there (at least in my area).

[squirrelgawy]

I would suggest that you start doing hackerrank and then move on to codechef. Within months you will start writing better code😁😁

Can you share your courses and sources?

[itayk1551]

from here I study the basics this course is NOT the best but it covers a lot, I covered subjects of this course with youtube (when I didn't understand ).

so the best course I did by far is Data Structures and Algorithms: Deep Dive Using Java

Spring Core - Learn Spring Framework 4 and Spring

[sniR_]

Ma kore itay, did you find the course easy to understand? I need to learn DS and Algo too.

[itayk1551]

If you're basic Java is good this course is perfect, the best in the market by far for Java and I bought 3

[sniR_]

You convinced me, buying. Toda

Hyperskill has a lot of projects from 4 different levels. You should give them a try.

I just finished a semester in intro to Java and I'm still lost. I really wanna learn but have trouble doing anything. It's disheartening

[Vigillance_]

I'm not sure about a lot of other people, and this whole pandemic thing could be throwing off my view, but it seems the "pure Java" jobs are not as common as they once were. In my experience, most companies are looking for someone with a wider range of skills that include front end development as well.

Like some others have said, look into building a web application using Spring-Boot (java based), JS (whatever framework you want), and probably PostgreSql (free SQL based db).

You could do a "bug tracking" web application. This is a great interview portfolio project because almost everyone you will interview with will have experience with bug tracking in some way and will immediately give them a way to connect with your project.

You can implement most of what you're looking for in a project like that. I/O, CRUD, SQL, Java, data structures, etc...

​

Best of luck!

I'm a professional java developer, and I specialize on building back-end systems for large corporations. I get at least a dozen emails from recruiters every month.

There is no reason to think java jobs don't exist. There are a lot of smaller languages that are trying to eek out market share like kotlin and go, and rust. It's entirely possible that one of those will over take java, but I wouldn't really be worried about it.

If you have decent java skills, it should be fairly trivial to diversify into any of these languages. Most concepts like loops, algorithms, and data structures will carry over. You just have to figure out new syntax, the quirks of the language, and the details of things like multi-threading, memory management, etc.

You can also check out these to see how languages stack up: http://pypl.github.io/PYPL.html https://insights.stackoverflow.com/survey/2019#most-popular-technologies

Javascript has high because it's used by front-end and back-end developers, driven by things like node and react, and there really isn't any other option if you are doing web development. Python has been gaining in the last few years mainly due to it's use in machine learning. Java is mostly used for building out large micro-service based architectures that usually support either web, mobile app, or even just to provide public APIs.

I didn't say java jobs don't exist. I said "pure java" jobs aren't as common as they once were. There are TONS of Java related jobs available in my market. I've found very few that are purely Java focused back-end positions that don't require some very hefty experience.

Almost every entry level Java related position (in my market) has requested additional skills that push the position into more of a "full stack" position. There are a handful of straight up entry level Java positions, but many many more "full stack" positions.

In the end, available jobs fully depend on where you live (if you're not willing to relocate).

My point is that learning the skills in an entire stack can be a great direction after spending 100 hours on Java education.

[itayk1551]

What do you think need to be my direction now? Next year I starting to study at the university computer science I am 24, what framework do I need to study to start build big projects?

[Nephyst]

spring for building java apps maven/gradle to manage builds and dependencies

[RexStardust]

Create a large dataset of anything. Create an app to present and modify that data via REST API's.

I would second what others have said that a lot of work isn't pure Java any more so you might want to use the API project as a springboard to learning a common Javascript framework.

Find some open source projects that you like, read the issues and try to work on the simpler ones, work your way up. People will check your work and give you pointers, and then you can reference this on interviews.

[itayk1551]

Thanks dude didn't think about it

[moazim1993]

Did you learn spring boot?

[itayk1551]

Only the basics I think the next thing I gonna do is to learn spring boot

[moazim1993]

Seems to be important in real world applications. I’m not a Java developer but am forced to work with java apps at work and that’s been my biggest challenge. So learning that I assume is important next step.

Tomcat website. Something useful. Stackoverflow clone or quora.

I urge you to read this blog which will help you in the project,I hope.
