Thread: Word Seach puzzle

What's wrong with this code? It is supposed to take in an array along with a sum to find. then it searches that array to find consecutive vertical or horizontal numbers that sum up to the sum you are looking for.

public class FindTheSums {
 
	public static String arrayToString(int[][] a) {
 
		String string = "";
        for (int row = 0; row < a.length; row++)
        {
                for (int col = 0; col < a[0].length; col++)
                {
                        System.out.print(a[row][col] + " ");
                }
                System.out.print("\n");
        }
        return string;
}
	public static int[][] horizontalSums(int[][] a, int sumToFind) {
 
		int currentSum = 0;
		int goalSum = 0;
		int[][] outputArray = new int[a.length][a[0].length];
		for (int row = 0; row < a.length; row++) {
			for (int col = 0; col < a[row].length; col++) {
				int currentPosition = col;
				currentSum = 0;
				int start = col;
				while (currentSum < goalSum) {
					currentSum = a[row][currentPosition] + currentSum;
					currentPosition++;
				}
				if (currentSum == goalSum) {
					for (int i = start; i < currentPosition; i++) {
						outputArray[row][i] = a[row][i];
					}
				}
			}
		}
		return outputArray;
	}
 
	public static int[][] verticalSums(int[][] a, int sumToFind) {
		int currentSum = 0;
		int goalSum = 0;
		int[][] outputArray = new int[a.length][a[0].length];
		for (int row = 0; row < a.length; row++) {
			for (int col = 0; col < a[row].length; col++) {
				int currentPosition = col;
				currentSum = 0;
				int start = col;
				while (currentSum < goalSum) {
					currentSum = a[row][currentPosition] + currentSum;
					currentPosition++;
				}
				if (currentSum == goalSum) {
					for (int i = start; i < currentPosition; i++) {
						outputArray[row][i] = a[row][i];
					}
				}
			}
		}
		return outputArray;
