a). Write a method called createArray which takes two parameters a and b, and returns an array that has all integer from a to b.   Example 1: a = 6, b = 2 Array is [6, 5, 4, 3, 2] Example 2: a = 4, b = 8 Array is [4, 5, 6, 7, 8] Example 3: a = 4, b = 4 Array is [4]   b). In main method, you should ask the user to input two integers a and b. Then call method createArray and print out the array.         class Main { public static int[] createArray(int a, int b) { } public static void main(String[] args) { } }

Write a java program to create prices of Shopping Cart items that provides a menu: 1: Create a new price for each item in the Cart list 2: Print the price of a particular item 0: Exit Enter your choice: Define an array: ShoppingCart which stores prices of items. Define another array: ItemsNames of the same size that stores names of such items. Assume that there are 10 items. When the user presses 1, the program call a method that creates a new price for each item in the array using random numbers between 1 and 1000 AED [not inclusive]. If the user presses 2, the program call a method that prints the name of the requested item and its price. Use switch case statement for choosing among the menu options. Make a method to display the menu to give the user the possibility to use the menu as much as he/she wants.

1. Write a class AnalyzeNumbers which asks the user to enter the number of inputs and stores them in an Array, then prints the Array that was inputted, calculates the sum of the numbers entered and prints the total numbers greater than the first inputted number: (15 points) Two Sample Runs Enter the number of items: 5 Enter the numbers: 3.4 5 6 7.1 9 You inputted: 3.4 5.0 6.0 7.1 9.0 Sum is: 30.5 Number of elements greater than the first element: 4 Enter the number of items: 3 Enter the numbers: 6.7 1.5 3.2 You inputted: 6.7 1.5 3.2 Sum is: 11.4 Number of elements greater than the first element: 0

Project Description: In this project you implement an ArrayStack ADT and use the stack for implementing the following methods: a) Reverse an array of Words: Accept an array of words as input parameter and return an array of words in reverse order. Use the method signature: public static String[] reverse Words (String[] wordList) Example Input: Bird Cat Dog Elephant Output: Elephant Dog Cat Bird

Write a method in your ArrayUtilities class that meets the following requirements: - It should be named "counts".] - It should declare a parameter for an int array. You may assume that the array will contain only non-negative values. - It should return an int array where the value at each index is the count of how many times the index appears in the original array . For example, if the original array contained the value 10 3 times, then the value at index 10 in the count array should be 3. - Hint: the size of the array is determined by the maximum value in the original array. If the original array is empty, the count array should also be empty. A more detailed example: Given the int array [1, 2, 3, 4, 4, 1, 1, 2, 0, 6], your function would return the array [1, 3, 2, 1, 2, 0, 1]. The value at each index indicates how many times the index appears in the original array. The value at index 0 is 1 because 0 appears 1 time in the original array. The value at index 1 is 3 because 1 appears 3…

JAVA ARRAY MANIPULATION QUESTION: make a method called manipulator that takes a double array as parameter and modifies it. The method will modify the array then print the array. The method must modify the existing array, it CAN NOT create a different array as the solution. The manipulator method will be a void method.   Remember: To get an average of 2 digits you add them together then divide by 2. Average of x and y = (x+y)/2   Modifications the method will do: For every 2 consecutive elements in the array, both the elements are replaced by their average.  If the number of elements in an array is odd don't modify the last number of the array.   Basically, you find the average of 2 consecutive elements then replace both of the elements with that value. Examples: Array = {2.0,3.0} will be changed to {2.5,2.5} when passed to the manipulator method Array = {2.0,3.0,45} will be changed to {2.5,2.5,45} when passed to the manipulator method Array = {2.0,3.0,45,55} will be changed to…

4. Remove all occurrences of a particular element from an array Consider an array named source. Write a method/function named removeAll( source, size, element) that removes all the occurrences of the given element in the source array. You must execute the method by passing an array, its size and the element to be removed. After calling the method, print the array to show whether all the occurrences of the element have been removed properly. nmm" Use Python Example: source=[10,2,30,2,50,2,2,60,0,0] removeAll(source,8,2) After calling removeAll(source,8,2), all the occurrences of 2 must be removed. Printing the array afterwards should give the output as: [ 10,30,50,60,0,0,0,0,0,0]

1. Square Roots Create a class with a method that, given an integer, returns an array of double-precision floating point numbers (known in Java as double), each of which is a square root of a number between 2 and the parameter to the method. For example, if the parameter is 5, the method should return an array of 4 doubles, with approximate values 1.4142135623, 1.7320508075, 2.0, and 2.2360679774. Your method should check the validity of the parameter, and take appropriate action if the parameter is invalid. 2. Reading Files Create a class with a method that, given a string representing a file name, returns an integer with the number of characters in the file. For example, if the file has 10 characters, your method must return the number 10. 3. Main Class Create a class HW1.java with a main method that does both of the following: calls the method from part 1 with a random integer between 0 and 10, and prints each of the numbers in the result. The numbers should all be printed on the…
