首先，我想说是的，我搜索过，我搜索得很辛苦，不幸的是，我没有找到任何对我来说足够好的答案，我想我知道该怎么做，但我不会＆＃39;我知道怎么做！好吧，我在我的程序中放了很多图像，效果很好，当我在计算机上运行时，图像出现并且没有问题，但我不能让图像出现在其他图像中电脑的！每当我把.jar放在另一台机器上时，图像就会消失......好吧，我想我必须创建一个带有images文件夹的包吗？但我不知道该怎么做，或者之后该做什么！如果有人可以给我一个完整的例子，那就太棒了......这是我的代码，请告诉我是否可以改进这个问题，我只是新来的！

答案 0 :(得分：2)
您应该使用ImageIcon(URL)并从类加载器获取资源URL，例如
ImageIcon info = new ImageIcon(IMC.class.getResource("/images/exclamaçao mario3.jpg"));
（顺便说一下，我避免在文件名中使用非ASCII字符。它可能很有用，但它只是可能出错的一件事。）
确保图像在您的jar文件中（例如，在＆＃34; / images＆＃34;在上例中）。
另请注意，您要在每个5位代码中加载相同的图像图标。我强烈建议您将加载并重复使用。
答案 1 :(得分：1)
ImageIcon(URL) 这是一个小工作示例。在这种情况下，图像位于src / resources中。
import java.awt.image.BufferedImage;
import java.io.IOException;
import javax.imageio.ImageIO;
import javax.swing.ImageIcon;
import javax.swing.JFrame;
import javax.swing.JLabel;
import javax.swing.SwingUtilities;
public class ImageViewer {
private final static String TITLE_IMAGE = "/resource/myimage.png";
private final JFrame frame;
private BufferedImage titleImage;
private JLabel titleLabel;
public static void main(String[] args) {
SwingUtilities.invokeLater(new Runnable() {
@Override
public void run() {
new ImageViewer();
}
});
}
public ImageViewer() {
frame = new JFrame();
init();
}
private void init() {
frame.setVisible(true);
frame.setSize(400, 300);
frame.setDefaultCloseOperation(JFrame.DISPOSE_ON_CLOSE);
try {
titleImage = ImageIO.read(getClass().getResource(TITLE_IMAGE));
titleLabel = new JLabel(new ImageIcon(titleImage));
frame.add(titleLabel);
} catch (IOException e) {
e.printStackTrace();
}
}
}

不要使用下面代码的swing部分。那很糟糕。只需使用加载图像的方式，它应该在你的jar中工作。
public class Test extends JPanel{
static BufferedImage image = null;
public static void main(String[] args) throws IOException {
image = ImageIO.read(Test.class.getClassLoader().getResourceAsStream("images/g.png"));
Test clz = new Test();
JFrame frame = new JFrame();
frame.add(clz);
frame.pack();
frame.setVisible(true);
}
@Override
public void paint(Graphics g) {
g.drawImage(image, 0, 0, image.getWidth(), image.getHeight(), null);
}
}
