I am also a newbie so I could be wrong, In your second line, you are trying to parse a string "ansewerToLife", in order to parse the int 42 from the variable you created you must pass in the variable answerToLifeAsString inside of the parseInt method.

The correct answer would be: int answer = Integer.parseInt(answerToLifeAsString);

You're passing a String with the contents "answerToLife" into a function that is trying to look for an integer to parse. :)

Try passing the variable you just created instead, which should have the integer you're looking for:

String answerToLifeAsString = console.readLine("42");
int answer = Integer.parseInt(answerToLifeAsString);
