Summing and Finding Maximum in 2d array

Question

So I have an 2d array of numbers and I am trying to find the maximum sum of the rows and give back the row number. So far I can get the sum and the maximum number but I need to give back the row number of the maximum value.
public static void RowSumRow (int[][] table)
      static int sum[] = new int[5];
      int region=0;
      for (int row=0; row < table.length; row++)
            sum [row] = 0;
            for (int col=0; col < table[row].length; col++)
               sum [row] = sum [row] + table[row][col];     
      int max = myMethods.maximumSearch(sum);
      System.out.println("The maximal revenue is $" + max + " at region " + region);
    }myMethods.maximumSearch
public static int maximumSearch(int a[])
     int Max = a[0];
     for (int index=0; index < a.length; index++)
         if(Max < a[index])
          Max = a[index];
        return Max;
   }

Answer 1

this is correct right?
(the prarmeter rows is the rows that are to be tested)
public static void RowSumRow (int[][] table, int rows)
      int sum[] = new int[rows];
      int region=0;
      for (int row=0; row < table.length; row++)
            sum [row] = 0;
            for (int col=0; col < table[row].length; col++)
               sum [row] = sum [row] + table[row][col];     
      int max = myMethods.maximumSearch(sum);
      for(int x=0; x < sum.length; x++)
          if (max == sum[x])
            region = x-1;
      System.out.println("The maximal revenue is $" + sum[region] + " at region " + region);
    }This does what I want it to do right? Ive tested a few times and it is working, but is it logically correct?
