Why aren't there no quote marks for ageAsString inside of Integer.parseInt?

Hi there,

The variable ageAsString is declared in the code. It is a String variable that is used to store the result of the readLine method. So, 

String ageAsString = console.readLine("How old are you? ");

asks the user a question and uses readLine to take the user's input. This input is then stored in the variable ageAsString which you will then convert to an int.

I hope that makes sense.

Steve.

So, variable names don't need quote marks around them - they exist in code without those.
