**** this is the error i am getting:
Exception in thread "main" java.lang.Error: Unresolved compilation problems:

Solution
There is a minor mistake in the else block you wrote. You just mistyped it seems. An open
paranthesis ( should be there in the else if condition, but you used open braces { it seems. Here is
the modificeation for you:

refinements, just get back to me.
