import javax.swing.*;

import java.awt.*;

            Icon ikon = new ImageIcon ("a.GIF");

            JLabel myLabel = new JLabel ("Selamat belajar JAVA", ikon,SwingConstants.CENTER);

            JButton myButton = new JButton ("SELESAI",ikon);

            myButton.setToolTipText("ini adalah Button");

            myLabel.setToolTipText("ini adalah Label");

            myFrame.setLayout (new BorderLayout());

            myFrame.add(myLabel, "South");

            myFrame.add(myButton, "North");

            myFrame.setSize(500,500);

}

public ContohJFileChooser (){

setSize(400,150);

JFileChooser jfc= new JFileChooser();

jfc.setFileFilter(filterDotJava);

int hasil = jfc.showOpenDialog(this);

if(hasil == JFileChooser.APPROVE_OPTION)

setTitle ("Tes JFileChooser.File: "+jfc.getSelectedFile().getName());
