Question

Which of the following String methods returns a negative value?

Options

• length()

• equals()

• compareTo()

• charAt()

Answer 1

compareTo()

Explanation:

compareTo() returns an int: a negative value if the first string is lexicographically less than the second, zero if they are equal, and a positive value if it is greater. For example, "COMPUTER".compareTo("SCIENCE") yields a negative result because 'C'comes before'S' in character order.
