         } else { 
            System.out.println("Not equal"); 
         }
  1. s1==s2
  2. s1.matchCase(s2)
  3. s1.equalsIgnoreCase(s2)
  4. s1.equals(s2)




Answer



C

Note

A compares equality of object reference.

B is incorrect because there is no method as matchCase.

D uses the equals method with the case which is different in the two strings.
