This last video was super confusing. I don't get why we couldn't just leave it as is. What is the need for the change?

Any additional resources for the last video would be super helpful. Thanks for your help!

ParsingInts.java 
String answerToLife = "42";

Hey Darian,

It would makes sense just leave it as is, as point of view being human. We(Humans) read as the example as number 42, but computer sees it as a String data type since it's enclose in quotes (" ").

String is a data type used to represent text rather numbers. It is comprised of a set of characters that can also contain spaces and numbers. Basically, anything that is enclose in quotation marks (" ") will be represented as text.

Integer is also a data type which represents whole numbers that be positive, negative, or zero.

It is best to rewatch the video, you'll need to use Integer.parseInt() for this code challenge.

Hi Darian,

The reason we do parseInt is to change a string into int format. here "42" is a string, you need to use parseInt() function to switch it to int.

Thanks
