我想使用JFC / Swing takekit将应用程序设置为动画GIF图像。我对这个工具包感到困惑

I just load an animated GIF images as an ImageIcon. The image of my Swing program running on Window 2000 PC Note that I am using Java/JDK 1.4.x release.

我只是将动画GIF图像加载为ImageIcon。在Window 2000 PC上运行的Swing程序的图像请注意，我使用的是Java / JDK 1.4.x版本。

Here is code, but it is not working:

这是代码，但它不起作用：

/**
  * DevDaily.com
* A sample program showing how to use an animated gif image
  * in a Java Swing application.
  */
package giftest;
import java.awt.*;
import javax.swing.JFrame;
import javax.swing.JPanel;
import javax.swing.JLabel;
import javax.swing.ImageIcon;
public class MainFrame extends JFrame {
    JPanel contentPane;
    JLabel imageLabel = new JLabel();
    JLabel headerLabel = new JLabel();

    public MainFrame() {
        try {
setDefaultCloseOperation(EXIT_ON_CLOSE);
            contentPane = (JPanel) getContentPane();
            contentPane.setLayout(new BorderLayout());
            setSize(new Dimension(400, 300));
            setTitle("Your Job Crashed!");
            // add the header label
            headerLabel.setFont(new java.awt.Font("Comic Sans MS", Font.BOLD, 16));
            headerLabel.setText("   Your job crashed during the save process!");
            contentPane.add(headerLabel, java.awt.BorderLayout.NORTH);
            // add the image label
            ImageIcon ii = new ImageIcon(this.getClass().getResource(
                    "snoopy_dancing.gif"));            imageLabel.setIcon(ii);
            contentPane.add(imageLabel, java.awt.BorderLayout.CENTER);
            // show it
            this.setLocationRelativeTo(null);

            this.setVisible(true)
        } catch (Exception exception) {
            exception.printStackTrace();
        }
}
    public static void main(String[] args) {
        new MainFrame();
    }
}

This code (which is functionally equivalent to the code seen above) works on Windows 10 using Java 1.8.

此代码（在功能上等同于上面的代码）适用于使用Java 1.8的Windows 10。

Check it runs as you expected on your machine. If so, it would seem that snoopy_dancing.gif is not in the location that the code expects.

检查它是否在您的机器上按预期运行。如果是这样，那么snoopy_dancing.gif似乎不在代码所期望的位置。

import java.awt.*;
import java.net.URL;
import javax.swing.*;

public class MainFrame extends JFrame {

    JPanel contentPane;
    JLabel imageLabel = new JLabel();
    JLabel headerLabel = new JLabel();

    public MainFrame() {
        try {
            setDefaultCloseOperation(EXIT_ON_CLOSE);
            contentPane = (JPanel) getContentPane();
            contentPane.setLayout(new BorderLayout());
            setSize(new Dimension(400, 300));
            setTitle("Your Job Crashed!");
            // add the header label
            headerLabel.setFont(new Font("Comic Sans MS", Font.BOLD, 16));
            headerLabel.setText("Your job crashed during the save process!");
            contentPane.add(headerLabel, BorderLayout.NORTH);
            // add the image label
            ImageIcon ii = new ImageIcon(
                    // this.getClass().getResource("snoopy_dancing.gif")); 
                    new URL("https://i.stack.imgur.com/OtTIY.gif"));
            imageLabel.setIcon(ii);
            contentPane.add(imageLabel, BorderLayout.CENTER);
            // show it
            this.setLocationRelativeTo(null);

            this.setVisible(true);
        } catch (Exception exception) {
            exception.printStackTrace();
        }
    }

    public static void main(String[] args) {
        new MainFrame();
    }
}
