Question

2. Design a class named Location for locating a maximum 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) Create TestLocation class and write a test program that prompts the user to enter a two-dimensional array and display the location of the largest element in the array, Here is an example run: Enter the number of rows and columns in the array: 34 Enter Enter the array 23.5 35 2 10 Enter 4.5 3 45 3.5 Enter 35 44 5.5 9.6 Enter The location of the largest element is 45 at (1, 2)

this language is JAVA

Answer 1

import java.util.Scanner;

public class LocateLargest {

    static class Location {

        private int x;
        private int y;

        public Location() {
            x = 0;
            y = 0;
        }

        public int getX() {
            return x;
        }

        public void setX(int x) {
            this.x = x;
        }

        public int getY() {
            return y;
        }

        public void setY(int y) {
            this.y = y;
        }
    }

    public static Location locateLargest(double[][] a) {
        Location location = new Location();
        for (int i = 0; i < a.length; ++i) {
            for (int j = 0; j < a[i].length; ++j) {
                if (a[i][j] > a[location.getX()][location.getY()]) {
                    location.setX(i);
                    location.setY(j);
                }
            }
        }
        return location;
    }

    public static void main(String[] args) {
        Scanner in = new Scanner(System.in);
        System.out.println("Enter the number of rows and columns of the array:");
        int rows = in.nextInt();
        int columns = in.nextInt();
        System.out.println("Enter the array:");
        double[][] a = new double[rows][columns];
        for (int i = 0; i < rows; i++) {
            for (int j = 0; j < columns; j++) {
                a[i][j] = in.nextDouble();
            }
        }
        Location location = locateLargest(a);
        System.out.println("The location of the largest element " + a[location.getX()][location.getY()]
                + " is at (" + location.getX() + ", " + location.getY() + ")");
    }
}

Enter the number of rows and columns of the array: 34 Enter the array: 23.5 35 2 10 4.5 345 3.5 35 44 5.5 9.6 The location of the largest element 45.0 is at (1, 2), Process finished with exit code
