10. Write a JAVA program to read the elements of a 5*5 integer array and then print the sum of all columns along with the index of the column in the output.

Write a program that asks the user to enter a series of 20 numbers. The program should store the numbers in an array then display the lowest number, highest number, the total of the numbers, and the average of the numbers.  using java different methods

Write a program to do the following task: Declare a two-dimensional array with 3 rows and 4 columns and fill it with random integers in the range of 0 to 100. Then create a one-dimensional array of doubles whose elements are the average values of each of the rows of the two-dimensional array. Output the two-dimensional array with the average of each row displayed at the end of each line.using java programming different method

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 //…
