. - Write a method called checkArrays that accepts as parameters two arrays of integer (A and B of the same size) and returns another array of integers (C) initialized as follows: C[i] = 1 if B[i] divides A[i], otherwise C[i]=0. For example: A 12 20 4 30 3 6 24 C 1 0 0 1 B Use the following method header: public static int[] checkArrays (int[] A, int[ 1 B) Sample Run: 15 Write a void method called printArray that accepts as parameters an array of integers and print its values. Use the following method header: public static void printArray (int[] arr) ArrayA: 12 ArrayB: 3: ArrayC: 1 17 260 9 Write a main method to test the above methods as follows: Declare and initialize 2 integer arrays (arrayA and arrayB) of size 5 (fill the 2 arrays with random integers between 1 and 100). Invoke the method printArray to display the values stored in the two arrays. Invoke the method checkArrays and pass to it the two arrays arrayA and arrayB. Invoke the method printArray to display the values of the…
Complete the method endsInFive that takes as arguments a 2D-array of integers and an integer value that represents a column index in the array. endsInFive returns the number of values in the column that end in 5. It is possible that the array is ragged, meaning that the number of columns in each row is different. For example, 2 is returned if the following 2D-array is passed as the first argument of endsInFive and the integer 3 as the second argument (the values 25 and 115 end in five at column index 3).
Image one is my file. Image 2 is my code(already have method 1 and 2) For my method 3, I want to write A method to find the index of the maximum value in an array takes one parameter, an array of integers returns the index at which the maximum value of the array occurs If the maximum value occurs multiple times, you may return the index of any occurrence
Task 2: Write a static method which takes an ArrayList of Strings and an integer and changes the ArrayList destructively to remove all Strings whose length is less than the integer argument. So if the integer argument is 4 and the ArrayList is: tomato cheese chips fruit butter tea buns pie The output tomato cheese chips fruit butter is:
Problem 1: Complete the sumOfDiagonals method in SumOfDiagonals.java to do the following: The method takes a 2D String array x as a parameter and returns no value. The method should calculate and print the sum of the elements on the major diagonal of the array x. In order to have a major diagonal, the array passed into the method should be a square (n-by-n), if it's not a square your program should handle that situation by throwing an exception. (Do Not worry about ragged arrays) If the array is a square, but there is a non-integer value on the major diagonal, your program should handle that situation by throwing an exception. When handling the exceptions, be as specific as you can be, (i.e. Do Not just use the Exception class to handle all exceptions in one catch block). Make the proper calls to the sumOfDiagonals method from the main method to test your sumOfDiagonals method on all the String arrays provided in the main method.
1) Write a method that returns the range of an array of integers. The range is the difference between the highest and lowest values in the array. The signature of the method should be as follows. public static int computeRange(int[] values)

Write a method that accepts a String as an argument and returns an int array. Assume that the string contains a series of single digit numbers separated by a comma. (e.g. 2,3,4,5). The method should return an array with the smallest element in the string. Hint: To convert a character to a string use the static toString method in the Character class.
Part 2: Coding 1. Write a complete Java program named FindAverage that contains the following: a. A main method that asks the user to provide the number of rows and columns for a 2- dimensional array of integers. b. A main method calls the getArray() method that creates the 2D array of specified size and populates it with random values from 0 to 100. c. A main method prints the elements of the 2D array created by getArray(). d. A main method calls the printAverage method that will: i. Receive the two-dimensional array as input ii. Calculate the average of elements in this array iii. Display the average on the console. The average of all elements should be formatted as xxx.XX. Hint: you can print the 2D array at any point in the program using either traditional for loop, foreach loop or available methods in java.util package. e. Add comments to your program. Start your program with the following header: *** *** ***** /**** ***
In JAVA Write the method below: Given a two-dimensional array containing integers, create a method called "matrixOperations" The method should do the following:1. Print out all the numbers in the array row by row (add empty line at the end of the row)2. For each row, print out the length of the row (each row is an array, remember)
The Lo Shu Magic Square is a grid with 3 rows and 3 columns shown below. The Lo Shu Magic Square has the following properties: The grid contains the numbers 1 – 9 exactly The sum of each row, each column and each diagonal all add up to the same number. This is shown below: Write a program that simulates a magic square using 3 one dimensional parallel arrays of integer type. Do not use two-dimensional array. Each one the arrays corresponds to a row of the magic square. The program asks the user to enter the values of the magic square row by row and informs the user if the grid is a magic square or not. Processing Requirements - c++ Use the following template to start your project: #include<iostream> using namespace std; // Global constants const int ROWS = 3; // The number of rows in the array const int COLS = 3; // The number of columns in the array const int MIN = 1; // The value of the smallest number const int MAX = 9; // The value of the largest number //…
