What does 'public static void' mean in Java?
java, methods
Solution
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 `private`, `protected`, `package` 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.
Problem
What does `public static void` mean in Java? I'm in the process of learning. In all the examples in the book I'm working from `public static void` comes before any method that is being used or created. What does this mean?
