私は三目並べゲームに取り組んでいます。現時点では、X と O は単なるテキストです。私はそれらが画像である必要がありますが、9つのボタンはすべて1つの変数にあります...

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

では、「O」の画像を取得するにはどうすればよいですか? if(count % 2 == 0)?

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

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