How to create a list with all the files in a folder using swing?

I want to create a list with a file name from a folder and show all the files that are present in this folder with a specific extension. I want the list to be selected so that I can select and delete a file from the list or edit it. I know how to select all files from a folder, but I don’t know how to show it in the GUI .

File folder = new File("c:/");
File[] listOfFiles = folder.listFiles();

enter image description here

This example shows how to list files in a directory and display them in JToolBarand JMenu. You can use Action, for example RecentFile, to encapsulate behavior for use in ListModeland ListSelectionListener.

See JFileChooser (shameless copy of the JFileChooser help page):

JFileChooser chooser = new JFileChooser();
FileNameExtensionFilter filter = new FileNameExtensionFilter(
    "JPG & GIF Images", "jpg", "gif");
chooser.setFileFilter(filter);
int returnVal = chooser.showOpenDialog(parent);
if(returnVal == JFileChooser.APPROVE_OPTION) {
   System.out.println("You chose to open this file: " +
        chooser.getSelectedFile().getName());
}

See file FilenameFilter?

setMultiSelectionEnabled (true); this is another hint.
