public int compareTo(Object o){ Treet other=(Treet)o; ....... } why do we need to explicitly type cast object 'o' to Treet when it is already referenced to treet object passed to its as an parameter??

public int compareTo(Object o)
The parameter is defined to have type Object, and therefore the cast to Treet is needed.
