Java: how to set .gif to the same size as the frame

Question

so I was messing around with a GUI and I wanted to challenge myself to display a gif. I ended up being able to do it but now I can't make the gif fit the entire frame instead of just a portion. I made the frame so you can't change the size and to be the same size as the monitor.

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

public class gif {
public static void main (String[] args) throws MalformedURLException {

    URL url = new URL("http://stream1.gifsoup.com/view2/1605810/paranoid-android-o.gif");
    Icon icon = new ImageIcon(url);
    JLabel label = new JLabel(icon);

    JFrame frame = new JFrame();

    Dimension screenSize = Toolkit.getDefaultToolkit().getScreenSize();
    label.setSize(screenSize);
    frame.setExtendedState(JFrame.MAXIMIZED_BOTH);
    frame.getContentPane().add(label);
    frame.setTitle("what?");
    frame.setSize(screenSize);
    frame.setResizable(false);
    frame.setVisible(true);

    }
}

I'm aware it's worded very poorly, any edits would be much appreciated — Spencer Hopkins, Sep 02 '16 at 20:30
I think you need to use the java Image package and rescale your image so it fits in the frame dimension. — Jean-François Fabre, Sep 02 '16 at 20:33

You might try to use HTML to load the image and specify the width & height in terms of % rather than pixels. — Andrew Thompson, Sep 03 '16 at 03:10

The JLabel will size itself based upon the ImageIcon inside. You can resize the image to the desired scale. For example:

BufferedImage image = ImageIO.read(url);
Image i2 = image.getScaledInstance(screenSize.width, screenSize.height, Image.SCALE_SMOOTH);
JLabel label = new JLabel(new ImageIcon(i2));
....

This being said, the input Image is an gif, so if animation exists in the Image you will have to take that into consideration. See this answer for resizing animated gifs.

I realize i could change it easily if it weren't animated, the problem with all the tutorials on how to do this already is i don't understand the syntax since they use a different method of putting the gif onto the frame – Spencer Hopkins Sep 02 '16 at 20:51
