public class JFileChooser extends JComponent implements Accessible
JFileChooser provides a simple mechanism for the user to
 choose a file.
 For information about using JFileChooser, see
 How to Use File Choosers,
 a section in The Java Tutorial.
 The following code pops up a file chooser for the user's home directory that sees only .jpg and .gif images:
    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());
    }

public JFileChooser()
JFileChooser pointing to the user's
 default directory. This default depends on the operating system.
 It is typically the "My Documents" folder on Windows, and the
 user's home directory on Unix.public JFileChooser(String currentDirectoryPath)
JFileChooser using the given path.
 Passing in a null
 string causes the file chooser to point to the user's default directory.
 This default depends on the operating system. It is
 typically the "My Documents" folder on Windows, and the user's
 home directory on Unix.currentDirectoryPath - a String giving the path

JFileChooser using the given File
 as the path. Passing in a null file
 causes the file chooser to point to the user's default directory.
 This default depends on the operating system. It is

                          the path to a file or directorypublic JFileChooser(FileSystemView fsv)

public void setDragEnabled(boolean b)
dragEnabled property,
 which must be true to enable
 automatic drag handling (the first part of drag and drop)
 on this component.
 The transferHandler property needs to be set
 to a non-null value for the drag to do
 anything.  The default value of the dragEnabled
 property
 is false.
 
 When automatic drag handling is enabled,
 most look and feels begin a drag-and-drop operation
 whenever the user presses the mouse button over an item
 and then moves the mouse a few pixels.
 Setting this property to true
 can therefore have a subtle effect on
 how selections behave.
 
 Some look and feels might not support automatic drag and drop;
 they will ignore this property.  You can work around such
 look and feels by modifying the component
 to directly call the exportAsDrag method of a
 TransferHandler.

 home directory on Unix.
 If the file passed in as currentDirectory is not a
 directory, the parent of the file will be used as the currentDirectory.

filechooser.showDialog(parentFrame, "Run Application");Alternatively, the following code does the same thing:
    JFileChooser chooser = new JFileChooser(null);
    chooser.setApproveButtonText("Run Application");
    chooser.showDialog(parentFrame, null);
 
 
 
 
 The parent argument determines two things:
 the frame on which the open dialog depends and
 the component whose position the look and feel
 should consider when placing the dialog.  If the parent
 is a Frame object (such as a JFrame)
 then the dialog depends on the frame and
 the look and feel positions the dialog
 relative to the frame (for example, centered over the frame).
 If the parent is a component, then the dialog
 depends on the frame containing the component,
 and is positioned relative to the component
 (for example, centered over the component).
 If the parent is null, then the dialog depends on
 no visible window, and it's placed in a
 look-and-feel-dependent position
 such as the center of the screen.

 This method can be overriden to further manipulate the dialog,
 to disable resizing, set the location, etc. Example:

         protected JDialog createDialog(Component parent) throws HeadlessException {
             JDialog dialog = super.createDialog(parent);

CONTROL_BUTTONS_ARE_SHOWN_CHANGED_PROPERTYpublic int getDialogType()
JFileChooser.OPEN_DIALOG.setDialogType(int)public void setDialogType(int dialogType)
OPEN_DIALOG when you
 want to bring up a file chooser that the user can use to open a file.
 Likewise, use SAVE_DIALOG for letting the user choose
 a file for saving.
 Use CUSTOM_DIALOG when you want to use the file
 chooser in a context other than "Open" or "Save".
 For instance, you might want to bring up a file chooser that allows
 the user to choose a file to execute. Note that you normally would not
 need to set the JFileChooser to use
 CUSTOM_DIALOG
 since a call to setApproveButtonText does this for you.
 The default dialog type is JFileChooser.OPEN_DIALOG.dialogType - the type of dialog to be displayed:
