Question

Make a BattleShip Game. There should be at least 2 ships of any size and the game board should be at least 5x5. First the computer will decide where to put it’s two or more ships. Then the user gets to decide where to put his/her two or more ships (or vise versa). Don’t duplicate code for the human and the computer. Now the game starts and the computer randomly chooses a coordinate (like A1) to torpedo making sure the same spot isn’t torpedoed twice. Also if a hit is confirmed, have the computer smart enough to choose the right next move! Next have the user choose a move, making sure that it is a possible move and a move that hasn’t already been played. Be sure to use JOptionPane, Switches, Loops, StringBuilder and arrays. There should be at least three classes created like, GameBoard.java, Player.java and BattleShip.java (what about maybe Ship.java). Make it user friendly with a smart AI!
