Question
Create a JAVA Battleship game
- use JFrames
- The game will be played automatically by a client and sever
- 4 ships each with a different size
- game board will be 100x100 blocks
Must have the following features:
- Config File for ships size and placement (Any ASCII format is accepted) (MUST be named ConfigFile.txt)
- A LogFile of the events of the application. (Time Stamped, and updated (append) for each game played):
-Capture errors that my occur (Such as missing or configfile not found.
-Log significant events (Such as start of game, win or lose game.
- Appropriate use of try catch blocks.
