Detailed designgame data structure designObviously, the only place where you need to store data is the nine map section.For maps, it is obvious that we can use two-dimensional array int [] [] game; To store the data in the map. However, although the two-dimensional array of int is straightforward, there are some inconveniences, such as the rich built-in processing method without the set. So, obviously, in the game map generation process, some auxiliary data we can adopt the Java collection.Map G

Recently, Singapore Prime Minister Lee Hsien Loong also wrote a code published, a general look, unexpectedly, is the code of coefficient alone!
