Depending on what you think, being an Oracle DBA is definitely popular as long as you are good at it, and the initial salary is higher than that of Java development. I can tell you this for sure; if you want to learn Java, you can do that too. , you can see that most of the training institutions now recommend Java. I believe it is because enterprises have an increasing demand for Java engineers. However, the early stage of doing Java is very hard, you have to learn a lot, and you may not be able to work in the company. Be taken seriously, and with the deepening of skills, I believe your future will be broad. I hope your future will be better for DBAs. Of course, if you just want to get by, you will definitely get worse.
