Those files are hidden, by default. If you look on the file system, you see they are there. — Andreas

Hey, if you're new to java I would really recommend starting out by writing your code in something such as notepad and compiling via the command line. This way you'll get a much better understanding of how to write code and the process of compiling it.

@Bradley I disagree. Having to compile your project and working without an IDE can make programming tedious and can demotivate people from coding. If you just want to code as a hobby, I recommend using IDEs. Of course, if you want to code as a job in the future, there could be some benefits from doing it your way, but that removes all of the fun. And why would you want to work something that's not fun? — Nikita Demodov

If your a hobbyist yes go for the IDE. I found it really rewarding when something I wrote within notepad compiled successfully! — Bradley

Those files you mention (.settings, .classpath, .project) are just metadata files from the IDE, and java does nothing with them, they are not part of a java project, the only thing you need to create a java program its a .java file. If you want to create a project, there are better ways, for example using maven https://maven.apache.org once you installed it, you can create a new project using the QuickStart archetype

mvn archetype:generate -DarchetypeGroupId=org.apache.maven.archetypes -DarchetypeArtifactId=maven-archetype-quickstart -DarchetypeVersion=1.4

It will create a standard structure for your project, and will save you a lot of work with the structure of your project, dependencies and build configurations.

To store project metadata some IDEs use additional files:

Eclipse uses .settings, .project, .classpath
Intellij uses .idea, .iml, .ipr, .iws

You don't need any of these for your project to work. If you use VSCode you don't need them at all.

Most modern java frameworks have quite comprehensive code generators for new projects which makes it easier to get started e.g.:
