JList - add scroll button

I have JList code that I want to add to a scroll button on the side since the list is longer than the text box window. that's the code:

final JList list = new JList();
        list.setBounds(36, 23, 366, 241);
        contentPane.add(list);
File folder = new File(FILETOSTART);
                        File[] listOfFiles = folder.listFiles();

                        for (int i = 0; i < listOfFiles.length; i++) {
                            if (listOfFiles[i].isFile()) {
                                System.out.println("File " + listOfFiles[i].getName());
                                list.setListData(listOfFiles);                              
                            } else if (listOfFiles[i].isDirectory()) {
                                System.out.println("Directory " + listOfFiles[i].getName());
                            }
                        }
                    }
                    in.close();
                }
                catch (Exception exception) {
                    exception.printStackTrace();

How can I add this scroll side button?

If by 'button' you mean 'scroll bar' then it can be1 as simple as:

contentPane.add(new JScrollPane(list));

Instead of:

contentPane.add(list);
  1. Except when using absolute positioning, as seems might be the case here.
