Our approach will be to display the dice throws from our previous homework, and display them graphically. For this exercise, we will restrict ourselves to displaying one face of 6-side dice. To extend the exercise, think about how you might handle other kinds of dice!What to Hand InPlease hand in a listing for each program requested, formatted in an easy-to-read style. Ensure your name, and the name of the file is available in a comment at the top of the file. Also, ensure that you have a sample of the output from the program. If your program fails to compile, hand in your error listing as your output. For each question asked, provide one or two sentences summarizing your answer. Please be both complete and succinct.ProblemsMake a graphical dice panel. If properly made, this Dice can be used and embedded in any of your game applications. Remember, you already have a Dice class, and this panel will leverage it. Create a class called DiceView which extends JPanel and implements ActionListener.Create a private data member to hold an object of type Dice Create a setter method for the Dice object.Create a public method for the ActionListener called actionPerformed which does the following: Checks if the ActionEvent action command is ‘Roll’If so, check the Dice instance to ensure it is non-nullIf the dice is non-null, roll() the diceCall repaint() Create a public method for the component called paintComponent, which does the following: Gets the size of the JPanel and sets local variables width and heightClears the rectangular area of the JPanel Draws a rectangle (or rounded rectangle), preferably a having equal sides, to fill most of the area in the JPanel (this represents the side of the dice)If the dice is not null, displays the value of the dice within that rectangleIf the dice is null, displays the text string ‘No Dice’ in that rectangleCreate a main program to test out your JPanel. You may use the following program, or modify it for your own purposes: public static void main(String[] args) { JFrame frame = new JFrame(); frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); JButton button = new JButton(‘Roll’); DiceView dv = new DiceView(); button.setActionCommand(‘Roll’); button.addActionListener(dv); Dice d = new Dice(); // To test what happens with no dice, comment out the next line dv.setDice(d); frame.add(BorderLayout.CENTER,dv); frame.add(BorderLayout.SOUTH,button); frame.pack(); frame.setSize(300,300); frame.setVisible(true); } NotesThis separation between the model (Dice) and the view and controller is called the MVC pattern, and is used throughout Java.The JPanel is found in package javax.swingThe ActionListener interface is found in package java.awt.event Calling repaint() arranges for the component to be redrawn as soon as convenient. The redrawing will invoke paintComponent at the right time.The public method for the ActionListener has the form: public void actionPerformed(ActionEvent e) The public method for the painting routine has the form: public void paintComponent(Graphics g). Note that even though Graphics is an abstract class, whatever implementation happens to be used (Graphics2D in this case), the right methods will be called without having to cast the parameter.To get the current size of the JPanel, you can use the getSize() method, which returns a Dimension (from package java.awt). This has attributes width and height.The Graphic methods clearRect, drawRect (or drawRoundedRect), and drawString should suffice for the actual drawing in the exercise. If you want to draw the pips on the dice, you will want fillOval.Note that the provided main program has no menus, and no exit button. However, it does arrange to close your application when the frame is closed (this is not the default!).This homework exercise is very extensible. Here are a few ideas for extending it: Add a second dice. Note that you could add one dice to the EAST and one to the WEST (leaving the CENTER empty). Also note that you will have to add each dice as ActionListeners for the button..Add an exit button. To make the button appear side-by-side with the other button, you must create a new JPanel, and put the existing JButton (Roll) in the EAST, and the new JButton (Exit) in the WEST. Then this JPanel is installed into the application the same way the old Roll JButton was, above. You need to attach an ActionListener to the button like so: class ExitHandler implements ActionListener { public void actionPerformed(ActionEvent e) { System.exit(0); } } This could be an inner class if you like.Add a row of dice. For this one, it is best to create a new class which extends JPanel and puts the dice in a GridLayout or a FlowLayout. An instance of this class, which could have an int parameter in its constructor, to tell you how many dice, can be placed in the CENTER, instead of the single dice. This is the way panels are nested to form a more complex displayAdd a menu. For this one, start simple–a File menu with an Exit button. You will use a JMenuBar, create a JMenu titled File, and a JMenuItem titled Exit. Your JMenuItem Exit pick must add an ActionListener, another instance as above in the Exit button case. Complete this as follows: Add the JMenu to the JMenuBar; add the JMenuItem to the JMenu, and then tell the frame to install the JMenuBar with frame.setJMenuBar(menubar); (or whatever you called your menu bar).
