Which of the following String methods returns a negative value?
- length()
- equals()
- compareTo()
- charAt()
Answer
compareTo()
Reason — The compareTo() method compares two strings lexicographically and returns an integer value which can be positive, zero, or negative depending on the comparison. The methods length() returns the length (non-negative), equals() returns a boolean, and charAt() returns a character, so none of them can return a negative value.
