CFSDN坚持开源创造价值，我们致力于搭建一个资源共享平台，让每一个IT人在这里找到属于你的精彩世界.

这篇CFSDN的博客文章Java实现两人五子棋游戏(七) 屏幕提示信息由作者收集整理，如果你对这篇文章有兴趣，记得点赞哟.

之前的两篇文章：java实现两人五子棋游戏(二) 画出棋盘；java实现两人五子棋游戏(三) 画出棋子；java实现两人五子棋游戏(四) 落子动作的实现；Java实现两人五子棋游戏(五) 判断是否有一方胜出；java实现两人五子棋游戏(六) 行棋方变换，可以点击查看.

接下来我们要实现的功能是在有五连珠的时候，在屏幕上提示信息。直接在mousepressed函数的iswin部分使用showmessagedialog即可.

mousepressed函数代码如下:
