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()
        Constructs a 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.

      • JFileChooser

        public JFileChooser​(String currentDirectoryPath)
        Constructs a 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.
        Parameters:

      • JFileChooser

        public JFileChooser​(File currentDirectory)
        Constructs a 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 typically the "My Documents" folder on Windows, and the user's home directory on Unix.
        Parameters:

      • setDragEnabled

        @BeanProperty(bound=false,
              description="determines whether automatic drag handling is enabled")
public void setDragEnabled​(boolean b)
        Sets the 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.

        Parameters:
        b - the value to set the dragEnabled property to
        Throws:
        HeadlessException - if b is true and GraphicsEnvironment.isHeadless() returns true
        Since:
        1.4

      • getDragEnabled

        public boolean getDragEnabled()
        Gets the value of the dragEnabled property.
        Returns:
        the value of the dragEnabled property

      • getSelectedFile

        public File getSelectedFile()
        Returns the selected file. This can be set either by the programmer via setSelectedFile or by a user action, such as either typing the filename into the UI or selecting the file from a list in the UI.
        Returns:
        the selected file
        See Also:
        setSelectedFile(java.io.File)

      • setSelectedFile

        @BeanProperty(preferred=true)
public void setSelectedFile​(File file)
        Sets the selected file. If the file's parent directory is not the current directory, changes the current directory to be the file's parent directory.
        Parameters:
        file - the selected file
        See Also:
        getSelectedFile()

      • getSelectedFiles

        public File[] getSelectedFiles()
        Returns a list of selected files if the file chooser is set to allow multiple selection.
        Returns:
        an array of selected Files

      • setSelectedFiles

        @BeanProperty(description="The list of selected files if the chooser is in multiple selection mode.")
public void setSelectedFiles​(File[] selectedFiles)

        Parameters:
        selectedFiles - an array Files to be selected

      • setCurrentDirectory

        @BeanProperty(preferred=true,
              description="The directory that the JFileChooser is showing files of.")
public void setCurrentDirectory​(File dir)
        Sets the current directory. Passing in null sets 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. If the file passed in as currentDirectory is not a directory, the parent of the file will be used as the currentDirectory. If the parent is not traversable, then it will walk up the parent tree until it finds a traversable directory, or hits the root of the file system.
        Parameters:
        dir - the current directory to point to

      • showOpenDialog

        public int showOpenDialog​(Component parent)
                   throws HeadlessException
        Pops up an "Open File" file chooser dialog. Note that the text that appears in the approve button is determined by the L&F.
        Parameters:
        parent - the parent component of the dialog, can be null; see showDialog for details
        Returns:
        the return state of the file chooser on popdown:
        • JFileChooser.CANCEL_OPTION
        • JFileChooser.APPROVE_OPTION
        • JFileChooser.ERROR_OPTION if an error occurs or the dialog is dismissed
        Throws:
        HeadlessException - if GraphicsEnvironment.isHeadless() returns true.
        See Also:
        GraphicsEnvironment.isHeadless(), showDialog(java.awt.Component, java.lang.String)

      • showSaveDialog

        public int showSaveDialog​(Component parent)
                   throws HeadlessException
        Pops up a "Save File" file chooser dialog. Note that the text that appears in the approve button is determined by the L&F.
        Parameters:
        parent - the parent component of the dialog, can be null; see showDialog for details
        Returns:
        the return state of the file chooser on popdown:
        • JFileChooser.CANCEL_OPTION
        • JFileChooser.APPROVE_OPTION
        • JFileChooser.ERROR_OPTION if an error occurs or the dialog is dismissed
        Throws:
        HeadlessException - if GraphicsEnvironment.isHeadless() returns true.
        See Also:
        GraphicsEnvironment.isHeadless(), showDialog(java.awt.Component, java.lang.String)

      • showDialog

        public int showDialog​(Component parent,
                      String approveButtonText)
               throws HeadlessException
        Pops a custom file chooser dialog with a custom approve button. For example, the following code pops up a file chooser with a "Run Application" button (instead of the normal "Save" or "Open" button): 
         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.

        Parameters:
        parent - the parent component of the dialog; can be null
        approveButtonText - the text of the ApproveButton
        Returns:
        the return state of the file chooser on popdown:
        • JFileChooser.CANCEL_OPTION
        • JFileChooser.APPROVE_OPTION
        • JFileChooser.ERROR_OPTION if an error occurs or the dialog is dismissed
        Throws:
        HeadlessException - if GraphicsEnvironment.isHeadless() returns true.
        See Also:
        GraphicsEnvironment.isHeadless()

      • createDialog

        protected JDialog createDialog​(Component parent)
                        throws HeadlessException
        Creates and returns a new JDialog wrapping this centered on the parent in the parent's frame. This method can be overriden to further manipulate the dialog, to disable resizing, set the location, etc. Example: 
             class MyFileChooser extends JFileChooser {
         protected JDialog createDialog(Component parent) throws HeadlessException {
             JDialog dialog = super.createDialog(parent);
             dialog.setLocation(300, 200);
             dialog.setResizable(false);
             return dialog;
         }
     }
        Parameters:
        parent - the parent component of the dialog; can be null
        Returns:
        a new JDialog containing this instance
        Throws:
        HeadlessException - if GraphicsEnvironment.isHeadless() returns true.

public void setControlButtonsAreShown​(boolean b)
        Sets the property that indicates whether the approve and cancel buttons are shown in the file chooser. This property is true by default. Look and feels that always show these buttons will ignore the value of this property. This method fires a property-changed event, using the string value of CONTROL_BUTTONS_ARE_SHOWN_CHANGED_PROPERTY as the name of the property.
        Parameters:
        b - false if control buttons should not be shown; otherwise, true

              description="The type (open, save, custom) of the JFileChooser.")
public void setDialogType​(int dialogType)
        Sets the type of this dialog. Use 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.
        Parameters:
        dialogType - the type of dialog to be displayed:
        • JFileChooser.OPEN_DIALOG
        • JFileChooser.SAVE_DIALOG
        • JFileChooser.CUSTOM_DIALOG
