Binary Search Tree into array

Hi, i need to store the nodes of a given binary search tree into an array in ascending order. i have come up with this:

publicstaticint[] collectNodesHelper(tree t){

int totalNodes = 0;

if(!isempty(t)){

collectNodesHelper(Left(t));

totalNodes = totalNodes + 1;

collectNodesHelper(Right(t));

}

int[] arr =newint[totalNodes];

for (int i=0; i<totalNodes; i++){

arr[i] = Root(t);

}

return arr;

}

which i'm fairly sure should work, but i am unsure about how to return - because where the statement is now, it says it cannot access variable arr.>
