How to create subdirectories in IntelliJ IDEA project in src directory?

Question

Java

I'm starting to learn Java with an IDE from JetBrains using video tutorials.

This video https://youtu.be/xvUFqDKIKJE?t=685 shows the folder structure in the project src > main > java > Start.java



I created a Java project in IDEA and it had a blue src directory. I decided to repeat the directory structure as in the video and create subdirectories in src, I pressed RMB > New, but there was no item in the drop-down menu to create a subdirectory.



Why is this and how to fix it?

Answer 1

Select create "package" - this is what you need

Answer 2

They are not directories, they are packages.

Answer 3

Good afternoon.
First of all, I wish you success in learning Java.

How to create subdirectories in IntelliJ IDEA project in src directory?

In Java, we operate not with directories, but with packages (Package), even though packages are essentially directories.
Right click on src and select New -> Package. Enter a package name.
To create a nested package, you can do the following:
1) Select the created package with the LMB (for example, com), and then New -> Package and enter the name of the new package.
2) Or there is a simpler way to create nested packages - to separate the names using the "dot" character.
When right-clicking on src , instead of just specifying a single name such as com, specify com.example.
I also recommend reading about the java naming convention and package naming rules.
