Question
Transcribed Image Text:Write a JavaFX GUI application that allows the user to pick a set of pizza
toppings using a set of check boxes. Assuming each topping cost 50
cents, and a plain pizza costs 10,ドル display the cost of the pizza. Note
that, once a topping is checked or unchecked, the cost of pizza should
update automatically.
Your application should closely resemble the following output format,
although the choice of toppings could be different:
Pizza Cost
Extra Cheese
Pepperoni
Sausage
Green Pepper
Onion
Anchovies
Pizza Cost: 10ドル.00

- Create a java application that prompts user for first name, last name, age, and GPA, then prints a summary of this information (see sample execution below): Follow this guide: Create 4 variables firstName, lastName, Age and GPA. You must use the most appropriate data type for each variable. Create a java scanner. Use Scanner to input the user’s information (First name, Last name, Age and GPA.) Using variables, print all that information.arrow_forwardWrite an application that counts by five from 5 through 500 inclusive and that starts a new line after every multiple of 50 (50,100,150 and so on).Save the file as CountByAnything.javaarrow_forwardA company approaches you to create an algorithm for calculating the tax and the tip on a restaurant bill. Assume that the application will only tip on the food and beverage total without the tax added in. Your algorithm will allow the user to input the amount of the tip in custom mode or your algorithm will give the tip in 12%, 15%, 18%, 20% recommended increments. Your job is to create the first three steps of the problem-solving process for this algorithm design. Please make sure that you explore the problem space to determine the criteria and constraints in Part 1. Be creative think of all the inputs and outputs you will be using. For Part 2 think of all the questions that you might have in determining how to actually make such a program. And for Part 3 make sure that you specify (pencil and paper – take a picture of it and include it in your document) a couple of examples of your algorithmic process.arrow_forward
- For the following program in phyton : Pay CheckWindow CostWrite an interactive program to calculate the cost of glasswork and metalstripping for rectangular windows. All windows, no matter what size, use thesame quality of glass and aluminum strips. Prompt the user for his/her name,age, length, and width of a window, then calculate the costs shown based on theinformation read in from the windowinfo.txt file which contains the materialstypes and costs (you cannot change this file at all). There is a discount on thetotal cost of 10% if the total area is over 1000 square inches, and 15% if it isover 1500 square inches.*Be sure to include a try/except and any and all string methods you might need*No conditional loops can be used at all**This is the info you will see in the text file, remember you mustread this in and store it:Glass: 80 cents per square inch (unit area)Aluminum: 1ドル.25 per inch (unit length) This is the sample output.

Clock12: Time should be displayed in 12-hour format where the clock does not exceed 12:59:59.2. Clock24: Time should be displayed in 24-hour format where the clock does not exceed 23:59:59.3. Both clocks should display on the screen with the current time in the proper format.Any clue where to even start? Title: Clocks FlowchartTop of chart begins: "Clear Screen" "Display time in two formats". Decision: "Button Pressed?" If "No" to button pressed, then to "Add 1 Second". Then "Wait 1 second". Then back to "Clear Screen". If "Yes" to button pressed, then to "Display Menu". Then "Read user input". Then to Decision: "User input = exit?". If "Yes" to exit, then endpoint: "End program". If "No" to exit, then Decision: "Add Hour?" If "Yes" to hour, then "Add 1 hour." Then back to "Clear screen". If "No"...arrow_forward
