$1.$ Software to sequence diagram context Consider the following program code: $//$MyFrame$.$java import javax.swing.JButton; import javax.swing.JFrame; public class MyFrame extends JFrame $\{$ public JButton button; public MyFrame$()\{$ this.setSize$(250,250)$; button $=$ new JButton$("$Go$")$; button.setSize$(100,100)$; button.setActionCommand$("$Go$")$; this.add$($button$)$; this.setDefaultCloseOperation$($EXIT$\_$ON$\_$CLOSE$)$; $\}\}//$MyListener$.$java import java.awt.event.ActionEvent; import java.awt.event.ActionListener; public class MyListener implements ActionListener $\{$ public static void main$($String$[]$ args$)\{$ MyListener listener $=$ new MyListener$()$; MyFrameframe $=$ new MyFrame$()$; frame.button.addActionListener$($listener$)$; frame.setVisible$($true$)$; $\}$ @Override public void actionPerformed$($ActionEvent e$)\{$ System.out.println$($e$.$getActionCommand$())$; $\}\}$ Task: How exactly does the interaction between the classes work when someone clicks the $"$Go$"$ button? a$)$ Create a sequence diagram for the interaction between the two classes, starting with the main method. Pay attention to the correct use of synchronous and asynchronous messages. b$)$ Correct the "Play Game" sequence diagram from the Connect Four example. Note: You are also allowed to run the code and examine it with an IDE.
