Chapter 17, Problem 3PP
Design and code a Swing GUI calculator. You can use Display 17.19 as a starting point, but your calculator will be more sophisticated. Your calculator will have two text fields that the user cannot change: One labeled "Result" will contain the result of performing the operation, and the other labeled "Operand" will be for the user to enter a number to be added, subtracted, and so forth from the result. The user enters the number for the "Operand" text field by clicking buttons labeled with the digits o through 9 and a decimal point, just as in a real calculator. Allow the operations of addition, subtraction, multiplication, and division. Use a GridLayout manager to produce a button pad that looks similar to the keyboard on a real calculator.
When the user clicks a button for an operation, the following occurs: the operation is performed, the "Result" text field is updated, and the "Operand" text field is cleared. Include a button labeled "Reset" that resets the "Result" to 0.0. Also include a button labeled "Clear" that resets the "Operand" text field so it is blank.
number in the "Operand" text field. Because values of type double are, in effect, approximate values, it makes no sense to test for equality with 0.0. Consider an operand to be "equal to zero" if it is in the range

In the second part of your project, you need to develop a mathematical worksheet graphical interface for elementary school students. The worksheet consists of 10 questions of operations between two random numbers. The operations are defined randomly from the set {+, -, *, /}. The GUI uses a text field to enter the maximum value of random numbers. A button with the caption "Check Answers" should be added to the GUI, and when clicked, a correct icon () should appear in front of the correct answer and an incorrect icon
value, which should then be output to the Fahrenheit field.
• The second button should perform the inverse function.
Be sure to use the field names provided in the comments in
your starter code.
An example of the program is shown below:

Extra 7-2 Add a stopwatch to the Clock application
In this exercise, you’ll add a stopwatch feature to a digital clock application. The stopwatch will display elapsed minutes, seconds, and milliseconds.
1. Open the application in this folder:
exercises_extra\ch07\clock_stopwatch\
2. In the JavaScript file, note the $(), displayCurrentTime(), padSingleDigit(), and DOMContentLoaded event handler functions from the Clock application. In addition, note the global variables and starting code for the tickStopwatch(), startStopwatch(), stopStopwatch(), and resetStopwatch() functions.
3. In the tickStopwatch() function, add code that adds 10 milliseconds to the elapsedMilliseconds variable and then adjusts the elapsedMinutes and elapsedSeconds variables accordingly. Then, add code that displays the result in the appropriate span tags in the page.
4. In the startStopwatch() function, add code that starts the stopwatch. Be sure to cancel the default action of the link too.

One slot is empty; the others are occupied by 15 square tiles numbered 1 through 15. The user can move any tile next to the currently empty slot into that slot by clicking that tile. Your app should create the board with the tiles in random order. The goal is to arrange the tiles into sequential order, row by row—that is, 1–4 in the first row, 5–8 in the second row, 9–12 in the third row and 13–15 in the fourth row.arrow_forward

The JLabel title of the GUI will say 'Pizza Servings Calculator' and be in red and will be placed in grid slot 1. A JLabel of 'Enter the size of the pizza in inches: ' will be placed in grid slot 2 followed by a JTextField where the pizza size will be entered and have a width of 4.

- For this task, you need to develop a JavaFX application in NetBeans that implements a LinkedHashMap class. The Java application should consist of a graphical user interface that can be used to add elements to the LinkedHashMap. There should be two TextFields to take in the element name and number. Then there should be four buttons to do four tasks, namely: add, change, remove and show all elements in the LinkedHashMap. Your buttons should have Action methods and should make use of methods in the LinkedHashMap class.When the Add button is clicked, the element name and value should be added to the LinkedHashMap. Make use of the LinkedHashMap methods to add the elements. When the user fills in the element name and number and the Add button is clicked, a message should be displayed in an alert dialog box to the user to inform them of this If no element is specified at the time the Add button is clicked, an error message should be displayed to inform the user to enter the elementarrow_forwardDon't Copy and paste answer from other websites CHAT Application Note: You must use Java FX GUIs!!!! DO NOT use SWING GUIs. Build a CHAT program, similar to a text-messaging app, to send text messages back and forth. That is you will build 2 programs, a client(ChatClient.java) and a server(ChatServer.java). If you enter a String on the Server and send it to the Client, the Client will display the Message it received. You will need to build a Java FX Gui for this project….you will also need to use Sockets to send the text across the network…..and I would also use Threads…..the new Thread you make will wait for data to come in and display it in the GUI TextArea. The GUI: Both the server program and the Client Program will have the exact same GUI.
