Java: Recursive tree function that shares a parameter?

Vote count:

If we're doing a print left view of a tree using a binary level print function, is there any way to pass around a shared parameter to all the recursive function calls?

For instance, in order to do print left view with a level order traversal, you check when the current level exceeds the max level encountered--this should be the first left node on the new level. Then all the other subsequent calls shouldn't have this issue. In C you have pointers so you can access the same address and change the max level seen, however, in java, what is the approach here
