Selecting Folder Destination in Java?

Question

I am a newbie to Java. I am trying to dynamically choose the file location to save the outcome of my project (to be initiated at the very start of my project). I worked around with a few FileDialog examples, but each one of them allows me to choose a file and not a folder.

Can anyone please help me with an example (or) link to one for the same?

You could try something like this (as shown here: Select a Directory with a JFileChooser):

import javax.swing.*; import java.awt.event.*; import java.awt.*; import java.util.*;   public class DemoJFileChooser extends JPanel    implements ActionListener {    JButton go;     JFileChooser chooser;    String choosertitle;    public DemoJFileChooser() {     go = new JButton("Do it");     go.addActionListener(this);     add(go);    }    public void actionPerformed(ActionEvent e) {                 chooser = new JFileChooser();      chooser.setCurrentDirectory(new java.io.File("."));     chooser.setDialogTitle(choosertitle);     chooser.setFileSelectionMode(JFileChooser.DIRECTORIES_ONLY);     //     // disable the "All files" option.     //     chooser.setAcceptAllFileFilterUsed(false);     //         if (chooser.showOpenDialog(this) == JFileChooser.APPROVE_OPTION) {        System.out.println("getCurrentDirectory(): "           +  chooser.getCurrentDirectory());       System.out.println("getSelectedFile() : "           +  chooser.getSelectedFile());       }     else {       System.out.println("No Selection ");       }      }    public Dimension getPreferredSize(){     return new Dimension(200, 200);     }    public static void main(String s[]) {     JFrame frame = new JFrame("");     DemoJFileChooser panel = new DemoJFileChooser();     frame.addWindowListener(       new WindowAdapter() {         public void windowClosing(WindowEvent e) {           System.exit(0);           }         }       );     frame.getContentPane().add(panel,"Center");     frame.setSize(panel.getPreferredSize());     frame.setVisible(true);     } }
