问题描述

我从事Java的记忆游戏已经有一个半星期了，知道它已经基本完成了，但是我在将jbutton随机分配到面板上时遇到了问题，它们仅以列表的顺序出现.所以最好是随机化或随机排列设置到每个按钮的图像和值的最佳方法，我一直在想这是静态网格布局，所以我无法更改它们的位置，我想我不久前就被怀疑了.图像在板上随机变化，但我无法找出如何将这些值与图像匹配，从而使游戏正常运行.

I have been working on a memory game in java for about a week and a half know it is basically complete, But i am having a problem with randomizing my jbuttons across the panel they only appear in the list order. So what would be the best way to randomize or shuffle the images and values set to each button i have been wondering it is a static grid layout so i cannot change the position of them, I thought i sussed in a while ago when i got the images to change randomly on the board but i could not find out how to match the values along with the images so the game would function properly.

    private static final Logger LOG = Logger.getLogger(Concentrate.class.getName());

    public static void main(String[] args)
    {  
        Concentrate concentrate = new Concentrate();
    }
}

上面是我的主类，它也构建框架并设置面板上的按钮，我将卡片图标存储在资源文件夹中，并定义了每个卡片图标在public focus()类中的哪个按钮

above is my main class which also builds the frame and sets the buttons along the panel i have the card icons stored in a resource folder and have defined which button each card icon is within the public concentrate() class 

    gameBtn[0].setDisabledIcon(new javax.swing.ImageIcon(getClass().getResource("/resources/images/c1.gif")));
    gameBtn[1].setDisabledIcon(new javax.swing.ImageIcon(getClass().getResource("/resources/images/c2.gif")));
    gameBtn[2].setDisabledIcon(new javax.swing.ImageIcon(getClass().getResource("/resources/images/c3.gif")));
    gameBtn[3].setDisabledIcon(new javax.swing.ImageIcon(getClass().getResource("/resources/images/c4.gif")));
    gameBtn[4].setDisabledIcon(new javax.swing.ImageIcon(getClass().getResource("/resources/images/c5.gif")));
    gameBtn[5].setDisabledIcon(new javax.swing.ImageIcon(getClass().getResource("/resources/images/c6.gif")));
    gameBtn[6].setDisabledIcon(new javax.swing.ImageIcon(getClass().getResource("/resources/images/c7.gif")));
    gameBtn[7].setDisabledIcon(new javax.swing.ImageIcon(getClass().getResource("/resources/images/c8.gif")));
    gameBtn[8].setDisabledIcon(new javax.swing.ImageIcon(getClass().getResource("/resources/images/d1.gif")));
    gameBtn[9].setDisabledIcon(new javax.swing.ImageIcon(getClass().getResource("/resources/images/d2.gif")));
    gameBtn[10].setDisabledIcon(new javax.swing.ImageIcon(getClass().getResource("/resources/images/d3.gif")));
    gameBtn[11].setDisabledIcon(new javax.swing.ImageIcon(getClass().getResource("/resources/images/d4.gif")));
    gameBtn[12].setDisabledIcon(new javax.swing.ImageIcon(getClass().getResource("/resources/images/d5.gif")));
    gameBtn[13].setDisabledIcon(new javax.swing.ImageIcon(getClass().getResource("/resources/images/d6.gif")));
    gameBtn[14].setDisabledIcon(new javax.swing.ImageIcon(getClass().getResource("/resources/images/d7.gif")));
    gameBtn[15].setDisabledIcon(new javax.swing.ImageIcon(getClass().getResource("/resources/images/d8.gif")));

如果我没有足够的描述性，他会表现出游戏的形象，但没有足够的声誉道歉，对此我还很陌生，但希望有人能足够友善并花点时间帮助我.

would have shown image of game but do not have enough reputation apologies if i have not been descriptive enough, I am fairly new to this but hope someone can be kind enough and take the time to help me out thanks.

推荐答案

那么随机化或随机化设置到每个按钮的图像和值的最佳方法是什么"

"So what would be the best way to randomize or shuffle the images and values set to each button"

只需使用

Just use Collections.shuffle() to shuffle the array of buttons. It takes a List argument, but you can just use Arrays.toList(). After the array is shuffled, then re-layout the panel with the buttons.
