Write code to create a two-dimensional array named numbers containing 500 random numbers from 1 to 1000 inclusive. The array has 50 rows. Then walk through the array and output the random numbers 10 to a line. Format the numbers in right-aligned columns. Use the command prompt window for output. Note: do NOT create a class or main.

create a new Java application called "Scorer" (without the quotation marks) that declares a two-dimensional array of doubles (call it scores) with three rows and three columns and that uses methods and loops as follows. Use a method containing a nested while loop to get the nine (3 x 3) doubles from the user at the command line. Use a method containing a nested for loop to compute the average of the doubles in each row. Use a method to...
Write a java code that Declares and initialize a two-dimensional int array named grades. It should have 10 rows and 6 columns where it stores the values and then calculates the average of all the elements in the grades array that you have declared
Row and columns sum Create a java program that: Input: Receive as input in command line the sizes m and n of a two dimensional array Receive as input in command line the minValue and maxValue between which the random numbers will be generated for your two dimensional array Generate: Generate a two-dimensional with numbers between minValue and maxValue (inclusive) with the given size (m x n) Compute: Compute the sum for each row and store the results in a...
Programing in Scala: Create a class called “Array” that implements a fixed-sized two-dimensional array of floating-point numbers. Write separate methods to get an element (given parameters row and col), set an element (given parameters row, col, and value), and output the matrix to the console formatted properly in rows and columns. Next, provide an immutable method to perform array addition given two same-sized array.
Write a menu based program implementing the following functions: (0) Write a function called displayMenu that does not take any parameters, but returns an integer representing your user's menu choice. Your program's main function should only comprise of the following: a do/while loop with the displayMenu function call inside the loop body switch/case, or if/else if/ ... for handling the calls of the functions based on the menu choice selected in displayMenu. the do/while loop should always continue as long...
