Expression (s instanceof java.util.Date) will return false if 's' was declared as a variable of class java.lang.String.
A) true
B) false

I answered this question but it was incorrect.My answer was A.Because I thought that expression would give us false.And I agreed that expression's evaluation, so I chose true.How my answer would be incorrect one, I didn't understand that.Please guys clarify this one.
