We know that the scripting variable state is true.

Why is this expression wrong? How would it be the code into _jspService method after translation?

The JSP expressions <%= ... %> are placed inside a out.print()

So <%= state ? "yes" : "no" %> is converted into out.println(state ? "yes" : "no");, which compiles without any problem. But with the if-statement the resulting code won't compile. That's also why semicolon in a jsp expression is not allowed.
