Something which I feel is escaping me about progress in learning Java is I guess the stuff surrounding it.  I'm being given a great opportunity to get into development and I've been working to learn java but there are pieces around it that I do not know how to learn.

When to use java code vs something else?  I needed to add a session time out to an application using spring.  I figured to make changes in the application.yml file but I could have done it with application class file as well.  I assume if they use spring then you use use spring over java ?

Diving to an already existing project for example.    Without asking someone, how do I know if the project is a maven or gradle or something else?   Is it simply whether you see a gradle.build file vs. pom ?

Is there a reason to use IntelliJ over Eclipse?   Another project I was just moved to, instructed me to use IntelliJ where I've been comfortable using Eclipse.

As it seems you're finding out, it's often a case of running into it on the job.  Different jobs and different companies will have different "stacks" (groups or technologies) that you will need.

Spring is a framework (a technology that helps you build something).  It's generally better to use a config file than change code.

You've got it: a Maven project will have a pom.xml file in the root of the project directory, and a Gradle project will have a gradle.build file.

This is usually company policy -- whether to use a certain IDE.  It makes sense for all developers to use the same one.  Then you can pass configurations and such between then.  It's mostly a matter of taste.

Thank You for responding to each of my questions.  I had a moment of frustration when I posted this.
