public T remove(T entry) { ReturnObject oldEntry = new ReturnObject(null); BinaryNodeInterface newRoot = removeEntry(getRootNode(), entry, oldEntry); setRootNode(newRoot); return oldEntry.get(); }

I'm trying to create a remove method for a binary search tree and this says it has inner class ReturnObject:

ReturnObject is an inner class that has a single data field and simple methods set and get to manipulate it. Initially, oldEntrys data field is null, since remove returns null when the entry is not found in the tree.

Can you please implement ReturnObject class. Thank you!!
