Your code is quite close, but there are a couple of small issues:

  1. The type for an integer variable is spelled int not Int. Correct capitalization is important when doing programming, to a computer int and Int are two completely different words even though they look quite similar to a human.

  2. You should only surround words with quote marks when you are creating a string, when you are referencing a variable you don't use quotes.

  3. You have misspelled the name of the answerToLife variable. You called it answertoLife (you forgot to capitalize the T in To).

If you fix all of those issues like this:

String answerToLife = "42";
int answer = Integer.parseInt(answerToLife);

Then your code will pass the challenge.
