我一直在使用java中的记忆游戏工作大约一个半星期才知道它基本上已经完成了，但是我遇到了一个问题，即在整个面板中随机化我的jbuttons它们只出现在列表顺序中。那么随机化或随机播放设置到每个按钮的图像和值的最佳方法我一直在想它是一个静态网格布局，所以我无法改变它们的位置，我想我不久前在我得到了图像在棋盘上随机变化，但我无法找到如何将这些值与图像匹配，以便游戏正常运行。

上面是我的主要类，它也构建框架并在面板上设置按钮我有卡图标存储在资源文件夹中并定义了每个卡图标在公共集中（）类中的哪个按钮
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[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")));
会显示游戏形象，但如果我没有足够的描述性，就没有足够的声誉道歉，我对此很新，但希望有人能够善待并花时间帮助我感谢。

“那么对每个按钮设置的图像和值进行随机化或随机播放的最佳方法是什么”
只需使用Collections.shuffle()来移动按钮数组。它需要一个List参数，但您可以使用Arrays.toList()。在对阵列进行混洗之后，使用按钮重新布局面板。
参见示例

import java.awt.GridLayout;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import java.util.Arrays;
import java.util.Collections;

import javax.swing.JFrame;
import javax.swing.JPanel;
import javax.swing.SwingUtilities;
public class ShuffleButtons {
private JButton[] buttons;
private JPanel gridPanel;
public ShuffleButtons() {
gridPanel = new JPanel(new GridLayout(4, 4));
buttons = getButtons(16);
layoutButtons();
JFrame frame = new JFrame("Shuffle Buttons");
frame.add(gridPanel);
frame.add(getResetButton(), BorderLayout.SOUTH);
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.pack();
frame.setLocationRelativeTo(null);
frame.setVisible(true);
}
public void shuffleButtons() {
if (buttons != null) {
Collections.shuffle(Arrays.asList(buttons));
layoutButtons();
}
}
public void layoutButtons() {
gridPanel.removeAll();
for (JButton button : buttons) {
gridPanel.add(button);
}
gridPanel.revalidate();
gridPanel.repaint();
}
private JButton[] getButtons(int size) {
JButton[] buttons = new JButton[size];
for (int i = 0; i < size; i++) {
final JButton button = new JButton(" [ " + i + " ] ");
button.addActionListener(new ActionListener(){
public void actionPerformed(ActionEvent e) {
System.out.println("Button " + button.getText() + " pressed");
}
});
buttons[i] = button;
}
return buttons;
}
private JButton getResetButton() {
JButton button = new JButton("RESET");
button.addActionListener(new ActionListener(){
public void actionPerformed(ActionEvent e) {
shuffleButtons();
}
});
return button;
}
public static void main(String[] args) {
