1,903 PointsI am confused on how to interpret this. Does it mean that if a user were to type in 42, the output would b answertolife?
String answerToLife = "42"; int answer = Integer.parseInt(answerToLife);

String answerToLife = "42";
// then we declare a variable 'answer' of type int and initialize it to using a method provided by the
// Integer-class. 'Integer' is an object wrapper class for the primitive variable type 'int', 'int' by itself doesn't
// contain any methods, but the wrapper class have a method called parseInt, which looks inside a string variable
// for numbers, and if there are numbers, then the method can convert the type from a String to an int.
int answer = Integer.parseInt(answerToLife);
// some examples:
System.out.printf("%d", answer);
// outputs --> 42
System.out.printf("%s", answerToLife);
// outputs --> "42"
Hope this helped.

1,903 PointsWhy does it return quotes when you put answerToLife and not when you put answer? Also, the lesson did not cover system.out.printf, only console.printf
