}

for(int i = 0 ; i < (int)Math.sqrt(BlockNum) ; i++ )

}

for(int i = 0 ; i < (int)Math.sqrt(BlockNum) ; i++ )

for(int j = 0 ; j < (int)Math.sqrt(BlockNum) ; j++ )

mainPanel.add(bombButton[ i ][ j ]);

c.add(mainPanel,"Center");

startBomb();

setSize(400,400);

setLocation(350,200);

setResizable(false);

}

代码没全拷过来 想问一下 怎么能让一个格周围的布雷不为零？？
