This article mainly introduces "how to achieve Gobang Mini Game with Java". In daily operation, I believe many people have doubts about how to achieve Gobang Mini Game with Java. The editor consulted all kinds of materials and sorted out simple and easy-to-use methods of operation. I hope it will be helpful to answer the doubts about "how to achieve Gobang Mini Game with Java". Next, please follow the editor to study!

By judging the score of each vacant position on the chessboard and removing the points with the highest score, the idea of calculating the score of playing chess at random:

If you can get five points, you can win and give the highest score.

Can not be 5, the other side can be 5, it means that the other side is going to win, give the second highest score

Can survive 4, give the third highest score

Can survive 3, give the fourth high score

Can become 4, give the fifth high score

Can go to Chong 3 and give the sixth highest score

Can survive 2, give the seventh high score

Can become Chong 2, give the eighth high score

In addition, setting the minimum score can be defined by yourself.

Here is an example of the code for AI Gobang:
