随机数发生器和TIC TAC TOE

Question

我目前正在努力思考课堂上提出的问题。在本学期早些时候，我有一项任务，我们必须使用GUI构建TIC TAC TOE游戏。快速查看我的程序是我有一个9 JButton数组，每个按钮也有事件监听器。这段代码非常简单直接。这是捕获，本周我们得到了我们的TIC TAC TOE程序，我们现在假设现在将AI作为播放器2。这并不像它看起来那么难，但是我需要一些来帮助我想象一个for语句或者一个while语句可以通过我的JButton数组9，如果已经按下了一个按钮，那么转到新的可用按钮。我有一些伪代码，我一直在脑力激荡，但似乎我的逻辑方法就是这样做。

伪代码

Random  number = New Randon(); 
JButton [] button = New JButton [9];

public void player2_AI()
{
    for( int x = 0; x <= button.length; x++)
    {
         button[x] = randomNumbers.nextInt(9) + 1
        if ( button[x].setEnabled(false))
        {
            button[x] = randomNumbers.nextInt(9) + [x]
        }
    }
}

为了帮助每个人想象我试图解决这个问题的方法，我会上传我的源代码，以便你们告诉我什么是最简单的方法让玩家2做出自己的决定（人造的）情报）
