Splash Screen Introduction
» A Splash Screen is an image that appears while a game or
program is loading…
» Splash Screens are typically used by particularly large
applications to notify the user that the program is in the
process of loading…
» Also, sometimes can be used for the advertisement
purpose …

Required Components
to Build a Splash Screen
» JTimer
» JProgressBar
» JWindow
7

JTimer (Swing Timer)
» A Swing timer (an instance of javax.swing.Timer)
fires one or more action events after a specified
delay.
˃ Do not confuse Swing timers with the general-purpose timer facility in
the java.util package.
» You can use Swing timers in two ways:
˃ To perform a task once, after a delay.
For example, the tool tip manager uses Swing timers to determine when to
show a tool tip and when to hide it.
˃ To perform a task repeatedly.
For example, you might perform animation or update a component that
displays progress toward a goal. 8

Text Clock Demo
import java.awt.FlowLayout;
import java.awt.Font;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import java.util.Calendar;
import javax.swing.JFrame;
import javax.swing.JTextField;
import javax.swing.Timer;
class TextClockDemo extends JFrame {
private JTextField timeField;
public TextClockDemo() {
// Customize JFrame
this.setTitle("Clock Demo");
this.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
this.setLayout(new FlowLayout());
this.setLocationRelativeTo(null);
this.setResizable(false);
9

// Customize text field that shows the time.
timeField = new JTextField(5);
timeField.setEditable(false);
timeField.setFont(new Font("sansserif", Font.PLAIN, 48));
this.add(timeField);
// Create JTimer which calls action listener every second
Timer timer = new Timer(1000, new ActionListener() {
public void actionPerformed(ActionEvent arg0) {
// Get the current time and show it in the textfield
Calendar now = Calendar.getInstance();
int hour = now.get(Calendar.HOUR_OF_DAY);
int minute = now.get(Calendar.MINUTE);
int second = now.get(Calendar.SECOND);
timeField.setText("" + hour + ":" + minute + ":" + second);
}
});
timer.start();
this.pack();
this.setVisible(true);
} 10

public static void main(String[] args) {
new TextClockDemo();
}
}

JProgressBar
» A progress bar is a component in a Graphical User
Interface (GUI) used to visualize the progression of an
extended computer operation such as
˃ a download
˃ file transfer
˃ or installation
» Sometimes, the graphic is accompanied by a textual
representation of the progress in a percent format.
13

JProgressBar Constructors:
» public JProgressBar()
JProgressBar aJProgressBar = new JProgressBar();
» public JProgressBar(int orientation)
JProgressBar aJProgressBar = new JProgressBar(JProgressBar.VERTICAL);
JProgressBar bJProgressBar = new JProgressBar(JProgressBar.HORIZONTAL);
» public JProgressBar(int minimum, int maximum)
JProgressBar aJProgressBar = new JProgressBar(0, 100);
» public JProgressBar(int orientation, int minimum, int maximum)
JProgressBar aJProgressBar = new JProgressBar(JProgressBar.VERTICAL, 0, 100);
» public JProgressBar(BoundedRangeModel model)
DefaultBoundedRangeModel model = new DefaultBoundedRangeModel(0, 0, 0, 250);
JProgressBar aJProgressBar = new JProgressBar(model);

JProgressBar Demo
import java.awt.BorderLayout;
import java.awt.Color;
import javax.swing.JFrame;
import javax.swing.JProgressBar;
public class JProgressDemo extends JFrame {
private static JProgressBar progressBar;
private Timer timer;
private static int count = 1;
private static int PROGBAR_MAX = 100;
public JProgressDemo() {
this.setTitle("JProgress Bar Demo");
this.setDefaultCloseOperation(EXIT_ON_CLOSE);
this.setSize(300, 80);
15

progressBar = new JProgressBar();
progressBar.setMaximum(100);
progressBar.setForeground(new Color(2, 8, 54));
progressBar.setStringPainted(true);
this.add(progressBar, BorderLayout.SOUTH);
timer = new Timer(300, new ActionListener() {
public void actionPerformed(ActionEvent ae) {
progressBar.setValue(count);
if (PROGBAR_MAX == count) {
timer.stop();
}
count++;
}
});
timer.start();
}
16

new JProgressDemo();
}
}

JWindow
» A Window object is a top-level window with no borders
and no menubar.
» The default layout for a window is BorderLayout.
» JWindow is used in splash screen in order to not be
able to close the duration of splash screen execution
and progress.
