如何编辑 IDE 的配置以运行 Java 应用程序...？ (IntelliJ)

Question

I know how to run my Java program from the command line. My path to Main.java is:

my_dir/turtlesolution

turtlesolution has the following:

Main.java
Turtle.java
Turtles.java

I opened turtlesolution as the project, using IntelliJ. I then opened (by double clicking) Main.java . I want to run this. I have to edit configurations before I run it, it seems.

So I clicked edit configurations . I clicked JAR application because this looks like the option. This is what comes up:

Working directory, I set it to point to turtlesolution . What is Path to JAR ? I tried to set it to turtlesolution but it remains blank. What does Warning, jar file doesn't exist mean?

I can run it from the command line by just doing

cd turtlesolution
javac Main.java Turtle.java Turtles.java
cd ../
java turtlesolution/Main

Aapprently it's very easy to figure out. I'm in my final year of learning CS in university and apparently it's simple, but I can't figure out how to do it, and it's too simple to teach ...

If you don't have any run configuration in the project, Run button is also disabled. If you right click in a file with main method, run configuration is created automatically and main class value if prefilled.
