无法更新Java Swing ImageIcon

这是我的全部代码，主要类和战争游戏类，如果它真的很混乱，请原谅我正在尝试让ImageIcon在每次单击按钮时更新

这是一款战争卡游戏，每次点击按钮都会更新图片

添加/删除组件后，应重新验证并重新绘制。尝试将这些添加到操作的末尾

我很难从我这边复制你的问题，因为我没有卡片图像，但是试试这个。在顶部声明卡片图像标签的地方，也实例化它们。JLabel player1Icon=新JLabel；。在战争游戏构造函数中，添加这些标签。在执行的操作中，取出addplayer1Icon和player1show=new JLabel，只需离开player1show.setIcon即可添加重新验证；重新油漆；没有解决问题。您能否发布运行的代码，我们可以使用这些代码尝试并帮助解决您的问题。完成。所以你让我直说了。您可以获得要显示的第一个图像，但在这之后，您无法获得要显示的另一个图像？或者根本无法显示任何图像？第一个图像显示，但之后的图像不显示。例如，第一次点击按钮：红桃王牌-显示2张黑桃-第二次显示：不显示任何内容，即使数字发生变化，也会有相同的图片。是每个玩家只需要一张牌，还是两张牌相加，这意味着当你再次绘制时，每个玩家会显示两张图片？
