Use a JFileChooser
, with JFileChooser.DIRECTORIES_ONLY
Take a look at this tutorial: How to Use File Choosers
JFileChooser chooser = new JFileChooser();
chooser.setFileSelectionMode(JFileChooser.DIRECTORIES_ONLY);
You want to select a folder in a swing application, right? you can use JFileChooser http://download.oracle.com/javase/tutorial/uiswing/components/filechooser.html
to select only a folder, look at this example http://www.rgagnon.com/javadetails/java-0370.html
for the saving, check http://download.oracle.com/javase/tutorial/essential/io/file.html
if you need something clarified, just ask.
I guess you want a Open File Dialog box.
In Swing it is called JFileChooser.
Usage example:
JFileChooser fc = new JFileChooser();
int returnVal = fc.showOpenDialog(yourJFrame);
if (returnVal == JFileChooser.APPROVE_OPTION) {
File file = fc.getSelectedFile();
// Do stuff with file
} else {
// User clicked cancel
}
yourJFrame should be the JFrame you use for your main window. If you don't have one put null
.
