What does ‘public static void’ mean in Java?

It’s three completely different things:

public means that the method is visible and can be called from other objects of other types. Other alternatives are privateprotectedpackage and package-private. See here for more details.

static means that the method is associated with the class, not a specific instance (object) of that class. This means that you can call a static method without creating an object of the class.

void means that the method has no return value. If the method returned an int you would write int instead of void.

The combination of all three of these is most commonly seen on the main method which most tutorials will include.
