我正在开发匹配照片游戏，我想我可以通过知道容器标签的名称来重置 imageIcon，然后在 ismatch 方法中返回 false 时重置标签图标。

在每个标签中写入以下代码，重置仅在第二个标签中起作用..我该怎么办？ 

public ImageIcon firstChoice;
    public ImageIcon SecoundChoice;
    public boolean isSelected = false;

    public boolean isMatch = true;

    public boolean ismatch(ImageIcon firstChoice, ImageIcon secoundChoce) {

        if (firstChoice.getImage() == secoundChoce.getImage()) {
            JOptionPane.showMessageDialog(null, " wowo you got it ^^");
            isMatch = true;
        } else {
            JOptionPane.showMessageDialog(null, "  notmatced");
            isMatch = false;


        }
        return isMatch;
    }


// label Mouse Clicked

private void label1MouseClicked(java.awt.event.MouseEvent evt) { 

    label1.setIcon(new ImageIcon("G:/Games/icons/File Server Asia.png"));

            if (isSelected == true) {
                ImageIcon icon1 = (ImageIcon) label1.getIcon();
                firstChoice = icon1;
                if (SecoundChoice != null && firstChoice != null) {
                }
                boolean match = ismatch(firstChoice, SecoundChoice);
                if (isMatch == false) {
                    label1.setIcon(null);
                    firstChoice = SecoundChoice = null;

                }

            } else {
                if (SecoundChoice == null) {

                    ImageIcon icon1 = (ImageIcon) label1.getIcon();
                    SecoundChoice = icon1;
                    isSelected = true;

                }


                if (isMatch == false) {
                    label1.setIcon(null);

                }

            }

}

我建议您不要将 ImageIcons 传递到您的ismatch(...)方法中，而是传递两个保存 ImageIcons 的 JLabel。然后在方法内部，您可以提取 ImageIcons 并比较它们，与以前相同，但更重要的是，您可以引用保存图标的 JLabels，然后您可以将它们设置为背景或空图标。

// "second" is mispelled
public boolean ismatch(JLabel firstChoiceLabel, JLabel secoundChoceLabel) {

    ImageIcon firstChoice = firstChoiceLabel.getIcon();
    ImageIcon secoundChoice = secoundChoiceLabel.getIcon(); 

    if (firstChoice.getImage() == secoundChoce.getImage()) {
        JOptionPane.showMessageDialog(null, " wowo you got it ^^");
        isMatch = true;
    } else {
        JOptionPane.showMessageDialog(null, "  notmatced");
        isMatch = false;

        // here set Icon to null or to background icon.
        firstChoiceLabel.setIcon(null);
        secoundChoiceLabel.setIcon(null);
    }
    return isMatch;
}
