java - 如何将图像插入 HashMap 中

Question

这是我的代码，我正在使用 GUI 和 JavaFX 创建一个堡垒之夜数据库，我想添加一个图像 Rockets.png，其中包含每个项目给出的信息，我该怎么做，我会把它放在这里

objList.put("火箭",new Ammo("火箭",2,12,"火箭专门用于爆炸性武器。" +“\nLTM 中的最大堆栈可能会有所不同，包括 Team Rumble。” + "\n所有弹药类型的堆叠数量是正常的两倍。"));

正如 @WJS 在上面的评论中所说，您可以在 HashMap 中存储您想要的任何数据类型。这是一个通用类型。

// You can store whatever you want in a HashMap, even Giraffes.
HashMap<String, Giraffe> zoo = new HashMap<String, Giraffe>(); // make a zoo for giraffes
zoo.put("Timmy", new Giraffe()); // add a giraffe
zoo.get("Timmy"); // returns Timmy the giraffe

要将图像添加到 javafx 应用程序，您可以创建一个新的 Image，然后在 ImageView 中显示该 Image。因此，在您的 Ammo 类中，创建一个新的实例字段来存储图像文件的路径。

每个 Ammo 对象都有自己的图像文件路径后，您可以执行以下操作:

if (null != myAmmoInstance.getImageFilepath()) { // avoid NullPointerException if there
                                                 // is ever an Ammo without an image
    Image image = new Image(myAmmoInstance.getImageFilepath()); // load the image
    ImageView imageView = new ImageView(); // make an ImageView
    imageView.setImage(image); // put the image in the ImageView to display it in the GUI
}

请注意 - 那里有十亿个图像类别。请务必使用 JavaFX Image 类，而不是 javax 类、awt 类或任何其他类，这些类在您的应用程序中不起作用。你明白了。
