Class JFileChooser
- All Implemented Interfaces:
- ImageObserver,- MenuContainer,- Serializable,- 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());
    }

Constructor Details- 
JFileChooserpublic JFileChooser()Constructs aJFileChooserpointing to the user's default directory. This default depends on the operating system. It is typically the "Documents" folder on Windows, and the user's home directory on Unix.
- 
JFileChooserConstructs aJFileChooserusing the given path. Passing in anullstring causes the file chooser to point to the user's default directory. This default depends on the operating system. It is typically the "Documents" folder on Windows, and the user's home directory on Unix.- Parameters:
- currentDirectoryPath- a- Stringgiving the path to a file or directory
 
- 
JFileChooserConstructs aJFileChooserusing the givenFileas the path. Passing in anullfile causes the file chooser to point to the user's default directory.

- 
setDragEnabled@BeanProperty(bound=false, description="determines whether automatic drag handling is enabled") public void setDragEnabled(boolean b) Sets thedragEnabledproperty, which must betrueto enable automatic drag handling (the first part of drag and drop) on this component. ThetransferHandlerproperty needs to be set to a non-nullvalue for the drag to do anything. The default value of thedragEnabledproperty isfalse.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 truecan 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 exportAsDragmethod of aTransferHandler.- Parameters:
- b- the value to set the- dragEnabledproperty to
- Throws:
- HeadlessException- if- bis- trueand- GraphicsEnvironment.isHeadless()returns- true
- Since:
- 1.4

- selectedFiles- an array- Files to be selected
 
- 
getCurrentDirectoryReturns the current directory.- Returns:
- the current directory
- See Also:
 
- 
setCurrentDirectory@BeanProperty(preferred=true, description="The directory that the JFileChooser is showing files of.") public void setCurrentDirectory(File dir) Sets the current directory. Passing innullsets the file chooser to point to the user's default directory. This default depends on the operating system. It is typically the "Documents" folder on Windows, and the user's home directory on Unix. If the file passed in ascurrentDirectoryis 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
- See Also:
 
- 
changeToParentDirectorypublic void changeToParentDirectory()Changes the directory to be set to the parent of the current directory.- See Also:

showOpenDialogPops 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- showDialogfor 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:
 
- 
showSaveDialogPops up a "Save File" file chooser dialog. Note that the text that appears in the approve button is determined by the L&F.- Parameters:

- Throws:
- HeadlessException- if GraphicsEnvironment.isHeadless() returns true.
- See Also:
 
- 
showDialogPops 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 parentargument 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 aFrameobject (such as aJFrame) 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 isnull, 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:
 
- 
createDialogCreates and returns a newJDialogwrappingthiscentered on theparentin theparent's frame. This method can be overridden 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 JDialogcontaining this instance
- Throws:
- HeadlessException- if GraphicsEnvironment.isHeadless() returns true.

UseOPEN_DIALOGwhen you want to bring up a file chooser that the user can use to open a file. Likewise, useSAVE_DIALOGfor letting the user choose a file for saving. UseCUSTOM_DIALOGwhen 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 theJFileChooserto useCUSTOM_DIALOGsince a call tosetApproveButtonTextdoes this for you. The default dialog type isJFileChooser.OPEN_DIALOG.- Parameters:
