Answer
Computer World equals COMPUTER WORLD false
Computer World equals Computer world false
Computer World equals computer world false
Computer World equalsIgnoreCase computer world true
Working
As the strings S1, S2, S3 and S4 differ in the case of the characters so equals() method will return false but equalsIgnoreCase() method will return true.
