//INSTRUCTIONS

### Problem 1: Blood Donor Eligibility  Add these components to DonorGUI.form. Ensure that you use these names. **JButton checkEligibilityButton** User will click this to check eligibility **JTextField weightTextField** for the user's weight in pounds **JTextField ageTextField** For the user's age in years **JLabel resultLabel** Will display if the user is eligible to be a blood donor or not Note that there are three final Strings defined in DonorGUI.java. The autograder expects you to use these to generate text for the resultLabel. In DonorGUI, add a click listener for the checkEligibilityButton. In the listener's onClick method, verify that the user has entered a positive number in both the weightTextField and ageTextField JTextFields. If either or both inputs are not valid (negative or not a number), the `resultLabel` JLabrl should display the `INPUT_ERROR` text. If both weight and age are positive numbers, use the data to decide if the user is eligible to be a blood donor. To be eligible, a person must be 17 or older, AND weigh 110 lbs or more. Display the `ELIGIBLE` text in the `resultLabel` JLabel if they are eligible. Display the `NOT_ELIGIBLE` text in the `resultLabel` JLabel if they are not eligible. Run and test your application. Take a screenshot of your application running and add it to the **screenshots** directory in this project. ### Problem 2: Agile or Waterfall?  Create a GUI . Add these components to AgileWaterfallGUI.form. Again, use these names. **JTextField projectName** **JSlider peopleOnTeam** This should take values between 1 and 300. Add JLabels with the text "1" at the start, and "300" at the end, to indicate the start and end values. **JCheckBox firmDeadlines** **JCheckBox experienceAllPhases** **JCheckBox qualityControl** **JCheckBox earlyIntegration** **JCheckBox earlyWorkingModels** **JButton recommendMethodology** **JLabel recommendation**  Add more JLabels as appropriate, for example, to label the JTextField and JSlider name and max and min values. . Add a click event listener to the `recommendMethodology` button. When clicked, this button will read the data entered, and recommend Waterfall or Agile or Either for a development method for the project. Display the recommendation in the `recommendation` JLabel. Use the provided Strings `AGILE`, `WATERFALL` and `EITHER` and `RECOMMENDATION_TEMPLATE` to display the result. Your GUI program should use a JLabel and the recommendationTemplate format String provided to display something like Big IBM Project could use Waterfall or My assignment could use Agile or "Banking App could use either" Take a screenshot of your application running and add it to the **screenshots** directory in this project. ### Problem 3: Gardener Invoices  You have been hired by a gardener to write a program to generate invoices. For this program, your program will generate text file invoices for some sample gardening services. The gardener offers two services: mowing, and leaf raking. The price structure is based on the size of the garden. To keep it simple, gardens may be small, medium, or large. The prices for a small garden are mowing = $15 ; leaf raking = $12 The price for each service for a medium garden is 2x that of a small garden. (So leaf raking in a medium garden is $24). The price for each service for a large garden is 3x that of a small garden. (So leaf pulling pulling in a large garden is $36) The invoices need to have:  * The customer name  * Address  * Date of service  * The size of the garden  * The mowing charge  * The leaf raking charge  * The total for all services  * Contact information for the gardener Build a GUI that allows the gardener to enter data about a customer and garden services performed. The program will generate a preview on an invoice. The gardener can review this, and then save it to a file. The GUI needs these components. Things you need to create and work with are in **bold**. A JPanel dataEntryPanel, containing the following components: * JTextField, customerNameTextField. This has been created for you. * JTextField, customerAddressTextField. This has been created for you. * JSpinner, serviceDateSpinner, to select date the garden service was done. This has been created and configured for you * **JComboBox** to select small, medium, large. Populate this from GardenServiceData's `size` array. Call it `gardenSizeComboBox` JCheckBox mowingServiceCheckBox - if mowing was done. This has been created. JLabel mowingServiceCost - to display the total cost for mowing services. * **JCheckBox** - if leaf raking was done. You need to create this. Call it `leafRakingCheckBox`. * **JLabel** - to display the total cost for leaf raking services. Call it `leafRakingCost`. * **JLabel** displays the total cost of all services. You need to create this. Call it `invoiceTotal` * JButton, generateInvoicePreviewButton, to generate invoice preview. This has been created for you. Another JPanel, invoicePreviewPanel, containing the following components * JTextArea, invoicePreviewTextArea, to display the invoice preview. This has been created for you. * JButton, saveInvoiceButton, to save invoice to disk. This has been created for you. You will not need to work with the JScrollPanel or JLabel in this JPanel. The user should be able to enter all information. Your program will calculate the totals based on what services are selected, and the size of the garden. As the user modifies the garden size JComboBox, and/or checks and unchecks CheckBoxes, the price for each service, and the total, should update automatically. If a service is not selected, the GUI should show "0.00" for the cost for that service. If no services are selected, the GUI should show "0.00" for the total cost. Totals should be displayed as numbers with 2 decimal places, you may add a $ if desired. So "$14.00" and "14.00" are both acceptable in the GUI. Dates in the invoice should be displayed as MM-dd-YYYY, for example, May 30 2017 would be "05-30-2017". On clicking the Invoice Preview button, use the methods in the Invoice Generator class to create a String, with the entire invoice. Display this in the JTextArea. The user will be able to make edits to this text. If the user does not select any services, and clicks the Invoice Preview button, show an error dialog. Clear the invoicePreviewTextArea. If the user does not enter a customer name or customer address, show an error dialog. Clear the invoicePreviewTextArea. On clicking the Save Invoice button, check to see if an invoice preview has been generated. If not, display an error dialog. If an invoice preview has been generated in invoicePreviewTextArea, use the methods in InvoiceWriter to write the invoice to disk. Usually, you'd warn the user that they are about to overwrite an existing file, but for this program, you can create the file if it does not exist, or overwrite it if if does exist. Use the InvoiceWriter.createFileName method to generate an appropriate invoice file name from the customer's name and the service date. Use the InvoiceWriter.writeToFile method to write the invoice. **If you need to show an alert dialog, or a String input dialog**, use the showMessageDialog and getStringWithDialog methods in GardenGUI. Take some example screenshots of your application running and add them to the **screenshots** directory in this project.
