20200612 minesweeper clone . Today's effort is a minesweeper clone, written in Java. This uses tty magic to clear the screen, so probably won't work on Windows. https://github.com/cratuki/console_minesweeper_java I feel strong satisfaction at having gone from nothing to a working github project within a day. The model of square enumeration I have chosen is rough and ready. Each possible square state is represented by a byte value. In retrospect, it would have been better to use bitmasking. Consider if each square would be represented by a byte of this structure, Low five bits: Number of neighbouring squares containing bombs (less than or equal to 8) High three bits:: is_bomb | is_marked | is_revealed The code required to work that structure would be tighter than today's effort. It has been four years since I attempted anything in Java, and far longer since I build anything that worked. Result.
