Does it make sense to write tutorial when content of the tutorial can be already learned from internet without that tutorial? For example, does it makes sense to write tutorial called Best Intellij shortcuts. You can already find so many shortcuts online in many places. If the answer is "There is no need for new article since many of them already exist" then why there is tons of tutorials how @Autowired annotation works? If you google for "spring @Autowired" you will find a lot of materials about how that annotation works, some written in back in 2012. and some of them in 2019 and they are almost totally the same. Also, I am sure that even before all of those articles that information was available in spring documentation. I think that the value of that new tutorial would be to highlight the best ten annotations.
Well, I'd suggest you should, for a couple big reasons:


Most people who are learning jump between resources and look for good ones. I often tell people who are learning something that if they're stuck and nothing makes sense, to try a different resource. It is just as often the fault of the resource as the person. For this reason, it is to learner's advantage to have lots of different resources they can try out there. Some like videos. Some think bullet list articles are great. Others want to sit down in a course. The internet caters to all of those choices.
As admirable as your goal of teaching others is, this should be just as much for yourself - indeed, one of the best ways of learning is teaching. Explaining something solidifies that understanding in your own mind.
It is good to learn how to convey your ideas - how to write well. I guarantee you that if you keep writing articles like this, you'll look back at the first one years later and see how far your writing style has come.
