Returning the Largest Element of a Two-Dimensional Array in java

Problem:

Write the following method that returns the location of the largest element in a two-dimensional array.

public static int[] locateLargest(double[][] a)

The return value is a one-dimensional array that contains two elements. These two elements indicate the row and column indices of the largest element in the two dimensional array. 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.

Output:

23.5 35 2 10
4.5 3 45 3.5
35 44 5.5 9.6
The location of the largest element is at (1, 2)

Solution:

  import java.util.Scanner;
  
public class LargestElement
{
  public static int[] locateLargest(double[][] a) 
  {
    double max = a[0][0];
    int i1 =0,j1=0;
    for (int i= 0;i <a.length;i++)
    {
      for (int j =0; j<a[i].length;j++)
      {
        if (a[i][j] > max)
        {
          max = a[i][j];
          i1 =i;
          j1 =j;
        }
      }
    }
    int[] bla = {i1,j1};
    return bla;
  }
  
  public static void main (String[] args)
  {
    Scanner scan = new Scanner (System.in);
    System.out.print("Enter the number of rows " +
                               "and columns of the array: ");
    double[][] nums = new double[scan.nextInt()][scan.nextInt()];
    System.out.println("Enter the array:");
    for (int i =0;i<nums.length;i++)
    {
      for (int j =0;j<nums[i].length;j++)
      {
        nums[i][j] = scan.nextDouble();
      }
    }
    int[] zizi = locateLargest(nums);
    System.out.println("The location of the largest element " +
        "is at (" + zizi[0] +", " +zizi[1] +")");
  }
}
