Images will not work in .jar file

Question

When an application JAR is created, images in the application are no longer displayed. Example of our code for uploading images:

ImageIcon placeHolder = new ImageIcon("src\\Cards\\hidden.png");

We do not know why this is happening. An application works as expected unless we compress it to a JAR; like a jar, images just fade away. We also tried using URLs instead of ImageIcons, but that just causes the program to not start at all.

Any ideas?

EDIT: we put image files in our JAR file in the correct paths so that there is no problem.

Tip . You can open .jar with any unzip program that supports ZIP to see its contents.

The answer . The way you refer to the resource is wrong, you should do something like getClass().getClassLoader().getResource("Cards/hidden.png").
