To create a graphical user interface application program in Java, there are a number of components that can be utilized. Specifically, you can use a frame or a panel to create objects. What are the differences between these two components? Provide an example that illustrates creating a simple GUI with an appropriate frame element. In response to your peers, provide an additional example on the GUI w/frame element that was posted.

Give an example of a program that creates a GUI with at least one button and several textfields. Some of the textfields should be for input and others for output. Make the output textfields uneditable. When the button is clicked, the input fields should be read, some calculation performed and the result displayed in the output textfield(s).

Is there any benefit to using a Java Layout Manager in your application? A panel's layout manager may be set up in a number of ways. How could you go about doing this, and could you provide an example of your method?

The event delegation model and its implementation in GUI development is a topic of much debate. Do not generalize; instead, provide concrete instances.

Is employing a Java Layout Manager advantageous for your application? The layout manager of a panel may be configured in several ways. Could you explain how you would approach this and give an illustration of your approach?

Write a main program that displays a single frame with the title “My First Frame”. Set the size to 800 by 800. Make the frame visible. Create a panel by using the JPanel constructor and add it to the frame. Use Color.RED (a constant in the java.awt package) along with the setBackground() method in JPanel, to set the color of the panel. Add a JButton and a JLabel to the panel before adding the panel to the frame. Display the results

Using JavaFX with Eclipse or Netbeans, please explain using a main class, controller class, and a FXML... Devise a JavaFX GUI with an internal controller class to maintain an array of arbitrary size. Use a starting default of size 20 and populate it with random data (numbers) initialized into the array. The GUI should be such that users can select and perform the actions listed below. Write methods and select appropriate GUI mechanisms to do the following: 1. Display the contents of the array2. Add a, or a group of numbers to the array at any position.3. Delete a number from the array at any position.4. Sort the array and display the original and sorted forms.5. Display the size of the array.6. Search for a number and its occurrences in the array and flag that number’s position(s) by highlighting it in the display.

In java pls!!!! thank you!

Why do we like the event delegation paradigm and its components in GUI development? Could you provide an example of an appropriate response?

Don Norman suggests organizing screens and menus functionally, designing commands and menu choices to be distinctive, and making it difficult for users to take irreversible actions. Norman also says to provide feedback about the state of the interface (e.g., changing the cursor to show whether a map interface is in zoom-in or select mode) and designing for consistency of actions (e.g., ensuring that Yes/No buttons are always displayed in the same order). State one example you have seen where you know these rules have been violated. Although this is crucial to a user interfaces success, suggest why there may be challenges to implement some of Norman’s guidelines.
