Java file list error

Java file list error

Hi i am creating an application that installs files into a selected jar. I
can't figure out how to fix the error in my list(Dir); method, It
recognizes all files and directories but when it tries to change its
directory (list(DIRECTORY);) it changes it to /originalDirectory/subFolder
i want to add a / after subFolder i've tried to do DIRECTORY + "/". But it
doesn't work any ideas? please.
My code:
public class DisplayContent extends JPanel implements ActionListener {
public DisplayContent() {
handleGraphics();
}
public String chosenDir = null;
public JButton btnInstall;

paneTitle.setBounds(55, 6, 330, 62);
paneTitle.setBackground(new Color(237, 237, 237));
paneTitle.setText("The Halo Ultimate Mod Installer");
add(paneTitle);
btnInstall = new JButton("Click Me To Install The Halo Ultimate
Mod");
btnInstall.setBounds(16, 134, 414, 47);
btnInstall.addActionListener(new ActionListener() {
