I am required in this code to use three different types of methods other than the main. The one I am having trouble with is on line 9, where I need to make a method that has one argument and returns void. In a separate file I got it to work by having the contents of the parenthesis in the header (String[] greetings) in the body of the method, but that would not fulfill my criteria of needing an argument.

The purpose of the custom method is to make a very simple array that gives me one of the four custom messages when run. I understand that it isn't the most practical use of an array, but I need to utilize it for an assignment.

I need that array to be inside the custom method as close to how it is as possible, so my question to you is how do i make that method compile correctly?

I am aware that the code as a whole will not compile correctly in its current state, the other fixes I know how to do. I really apologize in advance for any formatting errors, This is my first ever question on this website. I worked for many many hours on this with a tutor but we ran out of time.
