- In this lab work, you will implement a coffee shop example. In this coffee shop, everything must progress as if it does in real life. It means that the program should ask a person for body temperature in Celsius, and grant or reject access to a coffee shop. When a customer orders a coffee, they have to choose a size such as Small, Medium, and Large then, depending on the order, the price has to change. The price also has to change depending on the type of coffee. For example, for coffees that are similar to espresso, you also need to take every shot of espresso into account. The actual prices of the coffees depend on your imagination however, they should be realistic. Some hints: • Focus on dividing your program into multiple functions. • You can also return double or integer types of values from your functions, so use them if you can. • Don't just code a function every possible type of, and try to make it generic as much as possible. • Be creative. Fill the gaps using your…Write a program to print the names of books by creating a book class. If no name is passed while creating an object of book class, then the name should be "Unknown", otherwise the name should be equal to the String value passed while creating object of book class.Write a program that uses a bar chart to display the percentagesof the overall market share represented by Apple, HTC, Samsung, andOthers, as shown in Figure . Suppose that Apple takes 20 percent and isdisplayed in red, HTC takes 26 percent and is displayed in blue, Samsung takes28 percent and is displayed in green, and the Others take 26 and are displayedin orange. Use the Rectangle class to display the bars. Interested readers mayexplore the JavaFX BarChart class for further study.
- Computer Science Use only NumPy to create the Normalize Class: Image Normalization is a technique used to touch up images that are too dark or too light for the human viewing experience. Implement a version that outputs images with full dynamic range (0–255 pixel intensity). In other words, for each color channel (r, g, b), rescale the range of pixel values for that channel to include both 0 and 255. After normalizing, there should be at least one pixel with a red value of 0, at least one pixel with a red value of 255, at least one pixel with a green value of 0, etc. To normalize a list of numbers nums to the range 0–n, set nums[i] = (nums[i]−min(nums))/(max(nums)−min(nums))∗n for all i. Be careful! When max(nums) == min(nums), you should not touch that list (why?).UOWD Library is asking you to write a Java program that manages all the items in the Library. The library has books, journals, and media (DVD for example). All items have a name, author(s), and year of publication. A journal also has a volume number, while a media has a type (audio/video/interactive). The user of your program should be able to add an item, delete an item, change information of an item, list all items in a specific category (book, journal, or media), and print all items (from all categories). A menu asks the user which operation s/he wants to perform. Important: make use of collections, inheritance, interfaces, and exception handling wherever appropriate.write a program to print the names of the student by creating a student class .if no name is passed while creating an object of the student class,then the name should be "unknown" ,otherwise the name should be equal to the string valaue passed while creating the object of the student class.
- You've decided to test the wifi speed in the classroom at the beginning of every lecture. Create a program that will tell you if the wifi speed over the past 3 classes has increased, decreased, or neither. If the wifi speeds are sorted and increasing, then print out "The wifi is getting faster!". If the wifi speeds are sorted and decreasing, then print out "The wifi is getting slower!". If the wifi speeds are unsorted or if two or more speeds are the same, then print "The wifi speed is changing unpredictably." The user should input 3 non-negative numbers (double) separated by spaces. Sample runs: Enter wifi speeds over the last 3 classes: 162 180 225 The wifi is getting faster! Enter wifi speeds over the last 3 classes: 37.5 21.2 19.9 The wifi is getting slower! Enter wifi speeds over the last 3 classes: 162 135.3 225 The wifi speed is changing unpredictably. Ensure you are doing basic input validation, output Please enter a valid input. if the user inputs a negative wifi speed.

See Programming Project 8.7 (PP 8.7) from page 403 of your textbook (or view the attached image) for a description of what your program needs to do. Note that although the book description of the problem states that you should write the Card class, I do not want you to do that. You must use the Card file exactly as it is provided (NO modifications) and only write the DeckOfCards and Driver classes. public class Card{public final static int ACE = 1;public final static int TWO = 2;public final static int THREE = 3;public final static int FOUR = 4;public final static int FIVE = 5;public final static int SIX = 6;public final static int SEVEN = 7;public final static int EIGHT = 8;public final static int NINE = 9;public final static int TEN = 10;public final static int JACK = 11;public final static int QUEEN = 12;public final static int KING = 13; public final static int CLUBS = 1;public final static int DIAMONDS =…The file Parameters.java contains a program to test the variable-length method average.1.
