Extracted text: import java.awt.event.ActionEvent; import java.awt.event.ActionListener; import javax.swing.JFrame; import javax.swing.Timer; public class TimerExample extends JFrame implements ActionListener private final Timer myTimer = new Timer (1000, this); public void start () setsize (800, 600); setVisible (true); myTimer.setInitialDelay(15000); myTimer.start(); public void actionPerformed (final ActionEvent theEvent) // gets the current system time in milliseconds setTitle (String.valueof (System.currentTimeMilllis ())); public static void main (final string[] theArgs) final TimerExample example = new TimerExample(); example.start (); } When the main() method is run, how many times will the frame's title change in the first 20.5 seconds after the frame becomes visible? Show reasoning/calculations wherever possible. Note: Assume that it is the only non-system thread running in the virtual machine (and that therefore no unexpected delays are introduced in the operation of the timer). The class does compile as written, so do not look for syntax errors in the code
