Use the binary heap to return the k elements from largest to smallest

Question

I did code below. I started to build the maxHeap first and then removeMax. After that i stored it into an array from root, which is the largest element to smallest then I returned the k elements largest.
However, it said the error from line "Word result = wordArray[0];" in removeMax() method. Could someone help me to fix it?
