    Default A* algorithm help

    I have tried to use the piece of code to test out the A* algorithm and when I run it the values I get are wrong, can someone try and tell me if their are any gaping errors which i missed, If anyone doesn't know what the A* algorithm is, It is the algorithm used for path finding. Thanks in advanced

    public int[] pathfind(int currentX, int currentY, int finalX , int finalY)
        {
            int[][] grid = new int[3][3];
            int[] lowVals = new int[3];
            lowVals[2] = 2000000;
            for (int i = 0; i < 3; ++i)
            {
                for (int s = 0; s < 3; ++s)
                {
                    grid[i][s] = (finalX - currentX + (i-1) + finalY - currentY + (s-1));
                    if (grid[i][s] < lowVals[2])
                    {
                        lowVals[0] = i;
                        lowVals[1] = s;
                        lowVals[2] = grid[i][s];
                    }
                }
            }
            currentX += lowVals[0] - 1;
            currentY += lowVals[1] - 1;
            System.out.println(currentX + " " + currentY);
            return lowVals;
        }
