    Angry 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;
    	}
    }
    Tester class.
    public class FindTheSumsTester {
     
    	private static int[][] array1 = { 
    		{3, 2, 1, 1},
    		{2, 5, 6, 2},
    		{1, 2, 9, 8}
    	};
     
    	public static void main(String[] args){
    		arrayToStringTest();
    		horizontalSumsTest();
    		verticalSumsTest();
    	}
     
    	private static void arrayToStringTest() {
    		String methodCallResult, correctAnswer;
    		System.out.println("Testing arrayToString method:");
     
    		methodCallResult = FindTheSums.arrayToString(array1);
    		correctAnswer = "3 2 1 1\n2 5 6 2\n1 2 9 8";
    		if(methodCallResult.equals(correctAnswer)){
    			System.out.println("arrayToString(array1) test passed");
    		}
    		else{
    			System.out.println("arrayToString(array1) test failed");
    		}
    	}
     
    	private static void horizontalSumsTest(){
    		int[][] horizontalSums;
    		String arrayAsString;
    		System.out.println("Testing horizontalSums method:");
    		System.out.println("array1:");
    		arrayAsString = FindTheSums.arrayToString(array1);
    		System.out.println(arrayAsString);
    		System.out.println("horizontalSums(array1, 7):");
    		horizontalSums = FindTheSums.horizontalSums(array1, 7);
    		arrayAsString = FindTheSums.arrayToString(horizontalSums);
    		System.out.println(arrayAsString);
    	}
     
    	private static void verticalSumsTest(){
    		int[][] verticalSums;
    		String arrayAsString;
    		System.out.println("Testing verticalSums method:");
    		System.out.println("array1:");
    		arrayAsString = FindTheSums.arrayToString(array1);
    		System.out.println(arrayAsString);
    		System.out.println("verticalSums(array1, 22):");
    		verticalSums = FindTheSums.verticalSums(array1, 22);
    		arrayAsString = FindTheSums.arrayToString(verticalSums);
    		System.out.println(arrayAsString);
    	}
    }

    Desired output:
    25ae6dce537335dccf8aa5c5ecfb64ca.png3201391f593dba55e71541d15001fa85.jpg

    My output:

    Can you explain what is wrong with the current output?

    It is hard to see all the images at the same time for comparison.
    If you don't understand my answer, don't ignore it, ask a question.
