tldr; How do you use a MouseEvent on a JFrame object(specifically JLabel) to update the displayed image in the JFrame

I am trying to create a program where an image is broken into tiles and on click of one of those tiles, the program moves the tile to the open space in the image. (See Sliding Puzzle for more information).

I currently am able to select an image, break the image into tiles, and "randomly" remove one of the tiles.

My next step would be, on click of one of the tiles, to swap it with the empty tile (I will work on the "eligibility" of tiles to be swapped at a later time, but for now, just want to be able to swap the tile selected with the current blank tile)

To create my image for a 3x3 grid, I split a bufferedImage into 9 equal pieces, "randomly" blank one of the images, and then display the images in jLabels using GridLayout to line them up.

When I add mouseListeners to each jLabel, I am able to see that I am entering the MouseListener as I can see the console log message "Clicked" as shown below, however, am not able to update the image as desired.

How can I use a MouseEvent on these JFrame JLabels to call a method within ImageContainer(i.e. move()) and update the displayed image?
