Which statement is true? class Test1 { public int value; public int hashCode() { return 42; } } class Test2 { public int value; public int hashcode() { return (int)(value^5); } }

Correct Answer: The Test1 hashCode() method is less efficient than the Test2 hashCode() method.

Explanation:

The so-called "hashing algorithm" implemented by class Test1 will always return the same value, 42, which is legal but which will place all of the hash table entries into a single bucket, the most inefficient setup possible.


Option A and D are incorrect because these classes are legal.


Option B is incorrect based on the logic described above.
