	}

		// TODO Auto-generated method stub

	}

	@Override
	public void mouseExited(final MouseEvent e) {
		// TODO Auto-generated method stub

	}
}

3.代码常量部分

MineSweeperConstant.java：

public class MineSweeperConstant {
	final int row = 20;// 行数30
	final int col = 20;// 列数30
	final int LEICODE = 10;// 定义雷下方的数字
	protected int temp = 20;
	protected int leiCount = temp;// 雷数30
}

总结

不同的难度对应不同的地雷数量。
项目简单，容易上手，代码也容易理解。
