A personal phone directory contains room for first names and phone numbers for 30 people. Assign names and phone numbers for the first 10 people. Prompt the user for a name, and if the name is found in the list, display the corresponding phone number. If the name is not found in the list, prompt the user for a phone number, and add the new name and phone number to the list. Continue to prompt the user for names until the user enters quit. After the arrays are full (containing 30 names), do not allow the user to add new entries. Use the following names and phone numbers: Name Phone # Gina (847) 341-0912 Marcia (847) 341-2392 Rita (847) 354-0654 Jennifer (414) 234-0912 Fred (414) 435-6567 Neil (608) 123-0904 Judy (608) 435-0434 Arlene (608) 123-0312 LaWanda (920) 787-9813 Deepak (930) 412-0991     import java.util.*; class PhoneNumbers {     public static void main(String[] args) {         // Write your code here     } }

You have FOUR people selling  5  different kinds of flowers, so instead of a 4 by 4 array you had in the video (4 rows and 4 columns) you now have a 4 by 5 array (4 rows and 5 columns ) You may either use the names I had in the video or choose your own.  Instead of Brownies, you have flowers - petunia, pansy, rose, violet, and carnation.  Use a random number generator to generate the numbers of flowers sold, print out all the data as I did in the video.  The output should look like this: (numbers will vary because they are randomly generated)                    petunia pansy rose violet carnationFrankie      5               3          11      3            16 Janet          0              11         11    20            6 Sam           14            16          17    15            1 Abbie        8              20           0         6             8 Frankie sold 38 flowersJanet sold 48 flowersSam sold 63 flowersAbbie sold 42 flowers Total number of petunias sold: 27Total number of pansies…

# Create Custom Transformer Create a custom transformer, just as we did in the lecture video entitled "Custom Transformers", that performs two computations: 1. Adds an attribute to the end of the numerical data (i.e. new last column) that is equal to $\frac{x_1^3}{x_5}$ for each observation.  In other words, for each instance, you will cube the $x_1$ column and then divide by the $x_5$ column. 2. Drops the entire $x_4$ feature column if the passed function argument `drop_x4` is `True` and doesn't drop the column if `drop_x4` is `False`. (See further instructions below.) You must name your custom transformer class `Assignment4Transformer`. Your class should include an input parameter called `drop_x4` with a default value of `True` that deletes the $x_4$ feature column when its value is `True`, but preserves the $x_4$ feature column when you pass a value of `False`. This transformer will be used in a pipeline. In that pipeline, an imputer will be run *before* this transformer. Keep…

The Fibonacci numbers are 0, 1, 1, 2, 3, 5, 8, 13, ... where each number (after the first two values) is the sum of the previous two numbers. Write a program that declares an integer array called fib_numbers with a length of 25 elements. The program then fills the array with the first 25 Fibonacci numbers using a loop. The program then prints the values to the screen using a separate loop.

Array a is an integer array with all the elements in ascending order. The element at position 15 is the 15th largest and also the 15th smallest. You can assume integers are 4 bytes long. How many bytes are there in the array? O 116 124 O None of the other answers is correct. 120

The Chat-A-While phone company provides service to six area codes and charges the per-minute rates for phone calls shown in Figure 6-25 (below). Write a program named ChatAWhile that stores the area codes and rates in parallel arrays and allows a user to enter an area code and the length of time for a call in minutes, and then display the total cost of the call. For example if the area code is in the array, such as 715, and the call length is 22 minutes, the output should be: Your phone call to area 715 costs $0.16 per minute For 22 minutes the total is $3.52 If the area code is not in the array, such as 111, the program should not accept a call length, and instead output Sorry - no calls allowed to area 111. Area Code Per-Minute Rate ($) 262 0.07 414 0.10 608 0.05 715 0.16 815 0.24 920 0.14 Figure 6-25 Per-minute phone call rates In order to prepend the $ to currency values, the program will need to use the CultureInfo.GetCultureInfo method. In order to do this,…

Create an array of three string values that the fullName variable will use as a point of reference. Make an initialization list for the array using string values for the first, middle, and last names.

Can you write it in Java, add comments    Create an application containing an array that stores eight integers. Prompt the user to enter the 8 integers. The application should call five methods that in turn (1) display all the integers, (2) display all the integers in reverse order, (3) display the sum of the integers, (4) display all values less than the calculated average value, and (5) display all values that are higher than the calculated average value.

In this project you will generate a poker hand containing five cards randomly selected from a deck of cards. The names of the cards are stored in a text string will be converted into an array. The array will be randomly sorted to "shuffle" the deck.  Each time the user clicks a Deal button, the last five cards of the array will be removed, reducing the size of the deck size. When the size of the deck drops to zero, a new randomly sorted deck will be generated. A preview of the completed project with a randomly generated hand is shown in Figure 7-50.
