Why does "age" needs both "int" and "if", while "noun" only needs if?

Is it because the former uses the >, < and the latter uses equals?

You don't have to declare a new variable to check for the age, however it's better if you do it because it's easier to read the code and access the age (as an int) later if you need it, otherwise you have to convert the ageAsString everytime.

But this would work too:

String ageAsString = console.readLine("How old are you?  ");      
      if (Integer.parseInt(ageAsString) < 13) {
        //Insert exit code
        console.printf("Sorry you must be at least 13 to use this program.\n");
        System.exit(0);
      }
