how should we run
Sting Firstname ="aysuh";

I'm a bit confused by your question, but I'll just suppose you got an error running that code.
String Firstname = "whatever";
You typed "Sting" not "String". Also, if it's not a class name, the preferred way of naming variables would be camelCasing (no upper case letter at the start).
Hope this help! (Tell me if I got your question wrong)
