Javafx Path to a specific folder and select the file entered on textfield

Question

I wasn't very clear on my previous question, and I just rephrased it. Here is what I trying to achieve.

I want to define a path to a folder;
on the FROM ->TextField, Customer will enter the image name which already exist in the folder;
Click on a button and the file name will be added to the path and populate it to the imageView without manually browsing to the folder.

So, how can I do that? Thanks

Take a look at the answer from Allain and the modifications from mlh on in the above link. Or if you prefer you can just make your own file chooser that just shows a list of items from the directory in a jList. — sorifiend, Oct 02 '18 at 03:11
