My friend and I are working together to write a Java program, and I am taking on the task of designing the GUI. Our GUI requires a background image for the JFrame, and the image needs to be able to change based on the user's actions. I have placed the images that I want to use as the background in the project as a resource, and I would like to ask for help finding the resource path, and setting the resource path as the background image in the JFrame.
I am using the Swing GUI Builder for NetBeans to design the GUI. Can someone please offer me some help? I have no experience with GUIs, and my friend has little experience with basic Java coding, so we are assigning parts based on our knowledge.
