9.13 (The Location class)
Design a class named Location for locating a maximal value and its
location in a two-dimensional array. The class contains public data
fields row, column, and maxValue that store the maximal value and its
indices in a two-dimensional array with row and column as int types and maxValue as a double type.
Write the following method that returns the location of the largest
element in a two-dimensional array:
public static Location locateLargest(double[][] a)
The return value is an instance of Location.
Write a test program that prompts the user to enter a two-dimensional
array and displays the location of the largest element in the array.

import java.util.Scanner; public class Exercise_13 { public static void main(String[] args) { Scanner input = new Scanner(System.in); System.out.print("Enter the number of rows and columns in the array: "); int row = input.nextInt(); int column = input.nextInt(); double[][] m = new double[row][column]; System.out.println("Enter the array:"); for (int i = 0; i < m.length; i++) { for (int j = 0; j < m[i].length; j++) { m[i][j] = input.nextDouble(); } } Location location = Location.locateLargest(m); System.out.println("The location of the largest element is " + location.maxValue + " at (" + location.row + ", " + location.column + ")"); } }
how do find the smallest number and its location?
