import javax.swing.JButton;
import javax.swing.JFileChooser;
import javax.swing.JFrame;
import javax.swing.JLabel;

public class FileChooser extends JFrame implements ActionListener{
JButton open=null;
public static void main(String[] args){
	new FileChooser();
}
public FileChooser(){
	open=new JButton("open");
	this.add(open);
	this.setBounds(400,200,100,100);
	this.setVisible(true);
	this.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
	open.addActionListener(this);
}

public void actionPerformed(ActionEvent e){
	//TODO Auto-generated method stub
	JFileChooser jfc=new JFileChooser();
	jfc.setFileSelectionMode(JFileChooser.FILES_AND_DIRECTORIES);
	jfc.showDialog(new JTable(),"选择");
	File file=jfc.getSelectedFile();
	if(file.isDirectory()){
		System.out.println("文件夹:"+file.getAbsolutePath());
	}else if(file.isFile()){
		System.out.println("文件夹:"+getAbsolutePath());
	}
	System.out.println(jfc.getSelectedFile().getName());
}
private String getAbsolutePath() {
	// TODO Auto-generated method stub
	return null;
