How to run non-main Java classes in netBeans?

Question

Java

Good afternoon,
I created a project in netBeans , when I created the project, wizzard offered to create a main class, I named it Salut . Then I manually created several classes attached to the same package, but for some reason when I switch to these class files in the editor, Salut still starts . How to be right? I'm reading Eckel's book, nothing has been said about packages so far. How to run other classes?

Answer 1

In order to run a class, it must contain the main(String [] args) method.
I don't know about NetBeans, but in Eclipse - the context menu on the class -> Run as Java application.

Answer 2

Shift + F6

Answer 3

A similar situation arose, Shift + F6 starts the project, but when launched through the "green Play" it swears that the main class is not configured, the following helped me: Project properties -> Execution-> "Main class" field, looks like Package name. class name, choose from the list.
