Write the following funcion that returns the location of the

Write the following func.ion that, returns the location of the largest element in a two-dimensional list. The return value is a one-dimensional list that contains two elements. These two elements indicate the row and column indexes of the largest clement in the two-dimensional list. Write a test program that prompts the user to enter a two dimensional list and displays the location of the largest element in the list. Here is a sample run: Enter the number of rows in the list: 3 Enter a row: 23.5 35 2 10 Enter a row: 4.5 3 45 3.5 Enter a row: 35 44 5.5 11.6 The location of the largest element is at (1, 2)

Solution

LocationTest.java

import java.util.Scanner;

public class LocationTest {

   public static void main(String[] args) {
       Scanner scan = new Scanner(System.in);
       System.out.print(\"Enter the number of rows in the list: \");
       int rows = scan.nextInt();
       double d[][] = new double[rows][4];
       for(int i=0; i<d.length; i++){
           System.out.print(\"Enter a row: \");
           for(int j=0; j<d[i].length; j++){
               d[i][j] = scan.nextDouble();
           }
       }
       Location l = locateLargest(d);
       System.out.println(\"The location of the largest element is \"+l.maxValue+\" at (\"+l.row+\", \"+l.column+\")\");
      
   }
   public static Location locateLargest(double[][] a){
       double max = a[0][0];
       int row =0 , col=0;
       for(int i=0; i<a.length; i++){
           for(int j=0; j<a[i].length; j++){
               if(max<a[i][j]){
                   max = a[i][j];
                   row = i;
                   col = j;
               }
           }
       }
       Location l = new Location(row,col,max);
       return l;
   }
}

Output:

Enter the number of rows in the list: 3
Enter a row: 23.5 35 2 10
Enter a row: 4.5 3 45 3.5
Enter a row: 35 44 5.5 11.6
The location of the largest element is 45.0 at (1, 2)
