Question

THIS IS FOR JAVA PROGRAMMING:

Create the class Olympic

Ask and check for user name

Using a drop-down menu, ask the user to select a year from the list in the dialog box (between 2005 and 2020 -- inclusive, that is, include 2005 and 2020)

At the end, inform the user if the Summer Olympics were/will be held on the year selected (use a switch statement for that)

The code must:

Use dialog boxes to allow user input and messages to the user

Use While loops to check for invalid user inputs (e.g., empty strings, strings instead of numbers or vice-versa, negative numbers, floats instead of integers or vice-versa, etc.)

ImageIcon leftButtonIcon = createImageIcon("images/right.gif"); ImageIcon middleButtonIcon = createImageIcon("images/middle.gif"); ImageIcon rightButtonIcon = createImageIcon("images/left.gif"); b1 = new JButton("Disable middle button", leftButtonIcon); b1.setVerticalTextPosition(AbstractButton.CENTER); b1.setHorizontalTextPosition(AbstractButton.LEADING); //aka LEFT, for left-to-right locales b1.setMnemonic(KeyEvent.VK_D); b1.setActionCommand("disable"); b2 = new JButton("Middle button", middleButtonIcon); b2.setVerticalTextPosition(AbstractButton.BOTTOM); b2.setHorizontalTextPosition(AbstractButton.CENTER); b2.setMnemonic(KeyEvent.VK_M); b3 = new JButton("Enable middle button", rightButtonIcon); //Use the default text position of CENTER, TRAILING (RIGHT). b3.setMnemonic(KeyEvent.VK_E); b3.setActionCommand("enable"); b3.setEnabled(false); //Listen for actions on buttons 1 and 3. b1.addActionListener(this); b3.addActionListener(this); b1.setToolTipText("Click this button to disable " + "the middle button."); b2.setToolTipText("This middle button does nothing " + "when you click it."); b3.setToolTipText("Click this button to enable the " + "middle button."); ... } public void actionPerformed(ActionEvent e) { if ("disable".equals(e.getActionCommand())) { b2.setEnabled(false); b1.setEnabled(false); b3.setEnabled(true); } else { b2.setEnabled(true); b1.setEnabled(true); b3.setEnabled(false); } } protected static ImageIcon createImageIcon(String path) { java.net.URL imgURL = ButtonDemo.class.getResource(path); ...//error handling omitted for clarity... return new ImageIcon(imgURL);
