I have a java program that is supposed to compare the sums of the columns of a 2D array and output the index of the column with the largest sum. I was able to find the column sums but I do not know how to compare the different sums and output the index of the largest sum. Here is the piece of code that finds the column sums: int [] colSum = new int [arr[0].length]; for (int k = 0; k < colSum.length; k++) {       System.out.print(colSum[k]); ----> colSum[k] = the column sums How do I compare the integers in colSum[k] to find the largest sum and how do I output the index of the largest sum?

Question

I have a java program that is supposed to compare the sums of the columns of a 2D array and output the index of the column with the largest sum. I was able to find the column sums but I do not know how to compare the different sums and output the index of the largest sum. Here is the piece of code that finds the column sums:

int [] colSum = new int [arr[0].length];

for (int k = 0; k < colSum.length; k++) {

      System.out.print(colSum[k]); ----> colSum[k] = the column sums

How do I compare the integers in colSum[k] to find the largest sum and how do I output the index of the largest sum?
