Java Programming For an array of 20 integers (Declare all necessary variable). Write separate code segments to do the following (NOT a whole complete program). *   Adds up all even numbers and display their total.

Problem Description - JAVA PROGRAMMING Use a Two-dimensional (3x3) array to solve the following problem: Write an application that inputs nine numbers, each of which is between 1 and 10, inclusive.  Display the array after the user inputs each value. Rotate/flip the array by changing places. Make the rows columns and vice versa. You have to move the elements to their new locations.   Remember to validate the input and display an error message if the user inputs invalid data.  Documentation and the screenshot(s) of the results.  Example:  1  2  3 4  5  6 7  8  9 the result will be :  1  4  7 2  5  8 3  6  9

mergeAndRemove(int[], int[]) This is a public static function that takes a int[] and int[] for the parameters and returns an int[]. Given two arrays of integers. Your job is to combine them into a single array and remove any duplicates, finally return the merged array.

CODE IN JAVA design a program that grades arithmetic quizzes as follows: (Use the below startup code for Quizzes.java and provide code as indicated by the comments)   1. Ask the user how many questions are in the quiz.   2. Use a for loop to load the array.  Ask the user to enter the key (that is, the correct answers). There should be one answer for each question in the quiz, and each answer should be an integer. They can be entered on a single line, e.g., 34, 7, 13, 100, 8 might be the key for a 5-question quiz. You will need to store the key in an array called "key".   3. Ask the user to enter the student's answers for the quiz to be graded.  There needs to be one answer for each question. Note that each answer can simply be compared to the key as it is entered.  If the answer is correct, add 1 to a correct answer counter.  need this in a separate for loop from the loop used to load the array.   4. When the user has entered all of the answers to be graded, print the number correct…

Write a program in C as follows:- Create an array of integers named “toy” that has 120 rows and 4 columns.- The program should repeatedly display the following menu:A or a to add a toy to the bagV or v to calculate and display the total value of the toysW or w to calculate and display the total weight of the toysD or d to delete a toy from the arrayM or m to calculate and display the number of small toysN or n to calculate and display the number of medium toysL or l to calculate and display the number of large toysX or x to start filling a new bagP or p to exit program               - Santa’s bag can hold 30 large toys or 60 medium toys or 120 small toys or any combination ofsizes that satisfy this requirement (ex: 29 large + 1 medium + 2 small would be max capacity).Also, the total weight of toys cannot exceed 620 Kgs. All values are entered in centimeters andgrams. (Hint: the return values of the size function should help you in calculating the bagcapacity.)The…

I wrote this code in c programming.  what this code should do is ask how many times its going to run and run that many times(this works), ask how many books there are in a place(this works), then ask the max number of pages you want to read(this works), then asks how many pages there are in a book and put that into an array(works), then sorts the array of pages(works), and then adds the number in the array until you cant which is less than or equal to the max number of pages you want to read, and puts how many books you read(does not work), and then prints out how many books you read.   a sample input is 35 206 12 3 10 25 2112 3 6 10 210 319 6 6 3 8 2 12 15 13 7  sample out put should be 345    #include <stdio.h> #include <stdlib.h> void MergeSort(int values[], int start, int end); void Merge(int values[], int start, int middle, int end); void add(int pages[], int count[], long long maxPages, long long total); void Print_Array(int count[], int cases); int main(void) {…

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 //…
