Concept explainers
JFrame:
JFrame is a type of window that includes one or more instances related to JPanel. It is created by using Swing Graphical User Interface (GUI). It includes the feature like to hide or close the window using the method “setDefaultCloseOperation(int)”.
JApplet:
An applet class can be extended from “JApplet” class instead of “JFrame” class. “JApplet” is a Swing JPanel used for designing the web page or document. It is the extension of “Applet”. It is a Java bytecode that runs on Java Virtual Machine (JVM).
Abstract Window Toolkit (AWT):
AWT is an aggregation of Application User Interfaces (API) used for creating Graphical User Interface (GUI) objects like windows, scroll bars, buttons and many such.

- Step 1: Code in Java and name the java class file Artwork.javaStep 2: Have your JavaFx program set the Stage title to be your first and last name in the start method.Step 3: For this assignment, you are to create some simple JavaFx “generative art” Step 4: Your program must use one or more of the shape classes like Rectangle, Text, Circle, Arc, etc. (Refer to Javadoc page for ideas)Step 5: Your program must use one or more colors. (Refer to Javadoc page for ideas)Step 6: Your program must use java.util.Random to make the output change each time your program is run (for example, the colors, locations, and size of the shapes).Step 7: Describe the program and its behavior in a couple sentences. Note: Make sure to include the used javafx import statements in the solution box.arrow_forwardJava: Create the vehicle class UI transformation for the parking garage project as shown below: // Make sure the code is running with no errors • The parking lot has multiple levels. Each level has multiple rows of spots. • The parking lot can park motorcycles, cars, and buses. • The parking lot has motorcycle spots, compact spots, and large spots. • A motorcycle can park in any spot. • A car can park in either a single compact spot or a single large spot. • A bus can park in five large spots that are consecutive and within the same row. It cannot park in small spots. public enum VehicleSize { Motorcycle, Compact, Large } public abstract class Vehicle { protected ArrayList parkingSpots = new ArrayList(); protected String licensePlate; protected int spotsNeeded; protected VehicleSize size; public int getSpotsNeeded() { return spotsNeeded; } public VehicleSize getSize() { return size; } /* Park vehicle in this spot (among others, potentially) */ public void parkInSpot(ParkingSpot s) {…arrow_forwardWhat is a wrapper class? A A class that wraps a border around an image in a window. B A class that encloses related classes into a package. C A class that puts the finishing touches on a GUI project by adding a "theme" of related colors and style elements. D A class that wraps a primitive data type in an object so it can be stored in a collection.arrow_forward
- An interesting GUI component in Java is the Slider. Indeed, sliders allow a user to specify a numeric value within a bounded range.Write a program in Java using sliders to simulate the measurement of the temperature in Celsius using a digital thermometer. The following must be achieved: Design the thermometer using an appropriate shape and include the slider inside the shape with tick marks. Use proper layout managers and containers. The thermometer will measure temperatures between -20 oC and 110 oC upon sliding the GUI slider component. The temperature will be displayed in a text field or label. Using another label, a message will be displayed when the temperature reaches a certain value. For example, at -20 oC, the message “It’s ice cold” is displayed, at +10 oC, the message “It’s quite cold” is displayed, at +35 oC, the message “It’s hot” is displayed, etc.arrow_forward2. Write an interface for Tossable. We will say that every Tossable item has a way to toss it and we want to be able to give its color. A Tossable item by default is to throw an assist toss to another player.arrow_forwardUsing JavaFx Write a program to design a graphical user Interface for this system- Saloon Reservation System - Add Booking: The system will ask the user to enter the user information (Name, Phone number, Date Booked, service or anything related to your project. Once the Booking is added a message Booking confirmed with name and service, Date Booked will be displayed. - The System need to check if the same Phone number is available, then you can add service to the same user.- The System should check the availability of the time. Update Booking: Can update the booking date or service, etc.. for the user. Phone number is the primary key to check for user information. Delete Booking: delete the bookingSearch Booking: Search for the user Booking through Mobile Number. You cant have two people with the same phone number. Display the Booking information for the searching Criteria. Services: You should have a page that displays the services and its prices that your Business Offer.arrow_forward
- This is for pygame Text Class The Text class inherits from Drawable and it will be used to display the player’s score. You must implement at the very least the required methods of the base class (draw and get_rect), as well as a constructor. You may need to implement other methods as part of the public interface. This is the Drawable Classarrow_forwardCreate a VisualCounter class that supports both increment and decrement operations. Take the constructor inputs N and max, where N indicates the maximum number of operations and max specifies the maximum absolute value for the counter. Create a plot that shows the value of the counter each time its tally changes as a side effect.arrow_forwardUsing Java, solve the following problem using JavaFX: Write a program (Call the class ImageDisplay) that displays four images in a grid pane, as shown below. You are given 4 flags for the display, but you are free to choose other images. You are to use a GridPane for the layout. Also use ImageView. You will need to create an object for each image and use add method of GridPane to add an image to a specified row and column layout.arrow_forward
- Create a NetBeans project for this activity and create a Java GUI with events of a Simple Calculator based on the given screenshot below: The simple calculator should be able to display the computed result based on the operation. The Reset button should clear all values entered and displayed. When the Quit button is clicked, a JOptionPane window will display an information as shown before the program terminates. The program codes should be hard-coded.arrow_forwardJava Program See attached photo for the problem You do not need to make the GUI, if you want to make it then you go. I only need the program of the circled problems in red color.arrow_forwardRead the instructions below and write your code using Microsoft Visual Studio (Community version). Build your own console application with C#. Write a Rectangle class, the private data members are the length (len) and width (wid) of the rectangle, the parameterless constructor sets len and wid to 0, and the parameterized constructor sets the value of length (len) and width (wid). In addition, the class also includes common methods such as calculating the perimeter of the rectangle, calculating the area of the rectangle, obtaining the length value of the rectangle, obtaining the width value of the rectangle, and modifying the length and width values of the rectangle to the corresponding formal parameter values. Please upload your executable C# file as attachment in the system.arrow_forward
