Question

Function equals() is _______________ and equalIgnoreCase() is _________________

(a) Case Insensitive, case insensitive

(b) Case sensitive, Case insensitive

(c) Case sensitive, case sensitive

(d) Case insensitive, case sensitive

I have been asked this question during an interview.

Origin of the question is String Class topic in section Inbuilt Classes of Object Oriented Programming

Answer 1

Right answer is (b) Case sensitive, Case insensitive

The best I can explain: Both the functions return Boolean value. The function equal() is case sensitive and returns false even if a single character is case different in two strings. The other function ignores the case sensitivity and only checks if the spellings are same.
