What will be the output of the following code

StringBuilder s1 = new StringBuilder(“Yes”);
StringBuilder s2 = new StringBuilder(“Yes”); 

Console.WriteLine(s1 == s2);

s1 and s2 are different objects hence “==” returns false, but they are equivalent hence “Equals()” method returns true. Remember there is an exception of this rule, i.e. when you use “==” operator with string class it compares value rather than identity
