ImageIcon in swing package of Java not functioning correctly-CodePudding

I am having issues with creating an custom imageIcon in Java using swing. The file-name works, but it appears that the ImageIcon isn't changing at all. Here is the code:

ImageIcon icon = new ImageIcon("Hnet.com-image.png");
        JFrame frame = new JFrame("NumberPad");
        frame.setIconImage(icon.getImage());
        frame.setName("Pin Pad");
        frame.setContentPane(new NumberPad().NumberPadPanel);
        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        frame.pack();
        frame.setVisible(true);

Anyone got suggestions for what I should do?

You should make a compilable example.

public class IconCheck{
    public static void main(String[] args){
        JFrame frame = new JFrame("icon test");
        ImageIcon icon = new ImageIcon("Hnet.com-image.png");
        JLabel label = new JLabel(icon);
        frame.setIconImage( icon.getImage() );
        frame.add(label);
        frame.pack();
        frame.setVisible(true);
    }
}

Does that show your icon in the JFrame? If yes, then does it update your JFrame icon?

You probably want your png to be used as a resource.

ImageIcon icon = new ImageIcon( IconCheck.class.getResource("/sample.png") );

It looks up the path on the classpath, which intellij knows how to include.

Works now, thank you for helping me solve this issue!
