What does "missing main method for test.Test" mean?

Question

Java

Hello everyone, I'm trying to run the program and netBeans displays the main method for test.Test is missing.
What did I do wrong? I don't understand why this window is displayed.

Hello!
Means that the main method is missing, which you wrote incorrectly.
(you forgot to pass arguments to the method)
should be
instead
public static void main()
