Final Answer :
D
Explanation :
When comparing "Hello" to "Hi", the result of str1.compareTo(str2) will always be negative since "H" (the first letter of "Hello") comes after "H" (the first letter of "Hi") in the alphabetical order. Therefore, choices A, B, and C are all possible results. However, choice D, which is a positive number, could not be a result of str1.compareTo(str2).
