I'am new to programming and to ruby code, i'm having a hard time using the def method to use to call it up and display it. I get this error code:
C:/Users/Unknown/AppData/Local/Temp/rbB39C.tmp:4:in `board': undefined local variable or method `battleship' for main:Object (NameError)
from C:/Users/Coolwave/AppData/Local/Temp/rbB39C.tmp:31:in `<main>'

Any help would be great!! thanks

Please, stop abusing Ruby. Do not try to write Java or C++ code in Ruby.
Get some books and read.

Not sure what you mean what part is not ruby? i guess that's what i'm having problems with. I don't know Java or C++.
i'm in a course and i have this project that needs to be done. Any help would be great thanks. P.S i didn't know i was abusing ruby sorry.

You should move array declaration inside board method.
Also you can use only battleship=Array.new(9){[]} to define array.
