之前學完java基礎課程，試著簡單做了一下java的一個五子棋小游戲，記錄下來。

由于直接用的java庫中的一些基本控件寫的一個GUI，并沒有做過多優化，感覺比較丑下面是界面展示：

黑子先行，但是我這邊簡化規則，并沒有考慮黑子先行的一些禁手。

下面直接貼代碼

我把五子棋界面的一些常量都定義在了這個接口類中，包括棋盤的起始坐標，棋盤線的間距和棋子半徑

public interface constant { int[][] chessLocation = new int[15][15]; static final int x = 50; //左上角位置 static final int y = 50; static final int LN = 15; //棋盤一些常量 static final int R = 45;}實現類

接口

這個類中繼承了 constant、MouseListener、ActionListener三個接口

其中：

函數

show()繪制窗口基本框架paint()繪制棋盤網格線和棋子IsWin()判斷輸贏的基本邏輯mouseClicked()獲取鼠標位置，判斷棋子落點等actionPerformed()判斷鼠標點擊哪個按鈕（開始游戲or認輸or悔棋）執行相應操作

其中比較有趣的是五子棋判贏方式，假設棋盤大小15*15，則我只需要判斷正中間的13*13d的格子，向兩邊擴展，判斷是否五子連珠。

具體說明代碼里都有注釋，不多贅述。

public class Main_game { public static void main(String[] args) {game_logic start=new game_logic();start.ShowUI(); }}總結

實現了五子棋小游戲的基本功能，但是略感粗糙，細節不足。對于基本控件調用一學就會，做一個小的游戲demo這是對流程控制和操作邏輯的訓練很有效的一種方式。之前看了別人的代碼覺得簡單，但是自己寫的時候往往邏輯流程難以連續，思維混亂，有些過程只有自己寫了才知道其中的坑。
