我正在一個井字遊戲工作。目前，X的和O的只是文本。我需要他們的圖像，但是按鍵的所有9個都在1個變量...將圖片添加到按鈕

for(int i=0; i<=8; i++) { 
    buttons[i] = new JButton(); 
    mainframe.add(buttons[i]); 
    buttons[i].addActionListener(this);}

讓我怎麼得到的圖像的「O」，如果......如果（計數％2 = = 0）？

Icon icon = null; 
if(count % 2 == 0) 
{ 
    icon = iconThatIsO; 
} 
else 
{ 
    icon = iconThatIsX; 
} 

JButton pressedButton = (JButton)source; 
pressedButton.setIcon(icon);

看看How to Use Icons
