The document provides a Java implementation for a player versus computer Battleship game, detailing the game's user interface and mechanics. It includes methods for taking turns between the player and computer, ship placement, and proper handling of user inputs. Additionally, it features a menu system for game options and statistics tracking.

1. i need a taking turn method for a player vs computer battleship game in java. when a user slects
on players board then computer should be able to pick one on the computer board. this should
continue to repeat the order until the first one finds all the ship on their board first.
