import java.awt.Container;

import java.awt.FlowLayout;

import java.awt.event.ActionEvent;

import java.awt.event.ActionListener;

import java.io.File;

import javax.swing.JButton;

import javax.swing.JLabel;

public class SimpleFileChooser extends JFrame {

public SimpleFileChooser() {

super(“File Chooser Test Frame”);

setSize(350, 200);

setDefaultCloseOperation(EXIT_ON_CLOSE);

Container c = getContentPane();

c.setLayout(new FlowLayout());

JButton openButton = new JButton(“Open”);

JButton saveButton = new JButton(“Save”);

JButton dirButton = new JButton(“Pick Dir”);

final JLabel statusbar =

new JLabel(“Output of your selection will go here”);

// Create a file chooser that opens up as an Open dialog

openButton.addActionListener(new ActionListener() {

public void actionPerformed(ActionEvent ae) {

JFileChooser chooser = new JFileChooser();

chooser.setMultiSelectionEnabled(true);

int option = chooser.showOpenDialog(SimpleFileChooser.this);

if (option == JFileChooser.APPROVE_OPTION) {

File[] sf = chooser.getSelectedFiles();

String filelist = “nothing”;

if (sf.length > 0) filelist = sf[0].getName();

for (int i = 1; i < sf.length; i++) {

filelist += “, ” + sf[i].getName();

}

statusbar.setText(“You chose ” + filelist);

}

else {

statusbar.setText(“You canceled.”);

}

}

});

// Create a file chooser that opens up as a Save dialog

saveButton.addActionListener(new ActionListener() {

public void actionPerformed(ActionEvent ae) {

JFileChooser chooser = new JFileChooser();

int option = chooser.showSaveDialog(SimpleFileChooser.this);

if (option == JFileChooser.APPROVE_OPTION) {

statusbar.setText(“You saved ” + ((chooser.getSelectedFile()!=null)?

chooser.getSelectedFile().getName():“nothing”));

}

else {

statusbar.setText(“You canceled.”);

}

}

});

// Create a file chooser that allows you to pick a directory

// rather than a file

dirButton.addActionListener(new ActionListener() {

public void actionPerformed(ActionEvent ae) {

JFileChooser chooser = new JFileChooser();

chooser.setFileSelectionMode(JFileChooser.DIRECTORIES_ONLY);

int option = chooser.showOpenDialog(SimpleFileChooser.this);

if (option == JFileChooser.APPROVE_OPTION) {

statusbar.setText(“You opened ” + ((chooser.getSelectedFile()!=null)?

chooser.getSelectedFile().getName():“nothing”));

}

else {

statusbar.setText(“You canceled.”);

}

}

});

c.add(openButton);

c.add(saveButton);

c.add(dirButton);

c.add(statusbar);

}

public static void main(String args[]) {

SimpleFileChooser sfc = new SimpleFileChooser();

sfc.setVisible(true);

}

}

nah ini kode program saya dapet dari http://java2s.com/code/java/index.html.
