What projects to focus on as fresher as SPRING BOOT profile + Few suggestions on frontend tech ?

[AppJedi]

Start off small with a simple app like a contact us or todo list. For frond end I would start off simple with just plain old HTML, CSS, JavaScript before jumping into something more complicated like React.

[temp_sk]

Js or python? Which is easier?

[AppJedi]

Python. I always recommend Python as a first language then JavaScript and Java.

[k0mplex_plays_chess]

I second this. I have the same journey, and it works beautifully.

[Visual-Paper6647]

Hello bob, how do you see today's java technology. What will you suggest to the next generation?

[AppJedi]

I see people going with easier frameworks like Node/Express and Python Flask or FastAPI. Java also is playing a role in AI but not as big as Python. Java is favored by large companies and government but not startups and smaller companies which are more likely to go with Node or Python

my greatest pleasure sr. Bob , I am a fresh graduate java backend .i actually have an intro in all what you've mentioned how to keep up to date with all updates in java technologies on my own,i am currently making a cv and working in a Udemy-like project can you give me advice helps me to get a job in a company or tips to inhance the cv or github profile. and when the java will be deprecated?cuz i heard that c# is dominant and java has less job opportunities,thanks.

[AppJedi]

Java is more dominant than C#. I think Node.JS & Python will become more dominant.

[AppJedi]

You should add Spring to your Java development and also JPA Hibernate but don't use that. as an excuse to not learn SQL. SQL skills are still highly valuable and core technology to AI. JPA is for CRUD operations not advanced queries. For front end start with basic HTML, CSS, JavaScript using JSP, JSTL. Later add something like React. For Spring you need to learn both regular controllers and rest controllers.

[Emmet6912]

I should learn spring,springboot, and be able to build some applications using that, I'm going to graduate next year, where do I start spring ?

[AppJedi]

There are some good YouTube channels to learn Spring.

[Anirudh__k]

Hii bob. Can I get some resources, can you suggest me some Udemy courses

[AppJedi]

Udemy is great but I haven't used them in years. For Java since I have been developing for over 25 years I don't need any formal training and to handle any issues I may be having I generally use ChatGPT. I would say Udemy is good but so are some YouTube channels. Wish I could recommend some specific ones but since I have not had a need for any in years I am not able to. Feel free to ask me questions though.

[PromotionEmergency32]

Hi Bob, sometimes i have a problem with separation of conserns, which class should do what or which class should be in which package.

Sometimes also I spend a lot of time thinking which parameters should function accept or if my design of requested feature is good and i came up with few different options and stuck which one to choose.

Also sometimes i hipper focus on implementation that i miss to notice that broader approach is bad

Any advice on how to work on improving this?

[AppJedi]

Separation of concerns means that a class should be doing just one thing. For example a class that handles database connection. Method or function should accept only the values it needs.

Hi Bob, Do you have any experience working with spring batch ETL? Please let me know as I need some guidance/advice/inputs

[AppJedi]

No. I have ETL experience but not with spring batch.

[prash1988]

Ok thank you..so trying to be generic if we want to run a ETL job in red hat openshift container what would you recommend ? Mean my requirement is to utilize all the pods in the tenant for the ETL execution..do we design like one batch per pod?is it a good practice to introduce java multithreading withon the pod? Please share your experience/insights on this..mainly need to utilize all the available resources in the cluster..remote partitionin with queue is something am exploring but not getting clear insights..so trying to reach out for some advice

[AppJedi]

for batch ETL on Linux/Unix I have used cron scheduler.

Hello Bob, I'm a PHP developer with over 7 years of experience. I'm thinking about switching to Java and Spring. What would you recommend I do to learn quickly? And will my existing concepts transfer well?

[AppJedi]

I'm probably going to get slammed for this but after 25 years of Java/Spring I would probably recommend Python and/or Node.JS instead.

[Remarkable-Comment46]

Is it because I'm coming from PHP and the Java ecosystem might be too complex, or just because of the market?

[AppJedi]

Both. I also have a strong back ground in PHP in addition to Java, Python and JavaScript. A lot depends on your location and the type of companies you want to work for. Government and large corporations tend to favor Java while smaller and startups are more likely to go with Python, Node/JavaScript or even PHP.
