Why Int age = Integer.parseInt ??

In the program Craig created, he used Int age = Integer.parseInt(ageAsString);

I didnt get this, why he used Integer before parseInt, if he has already mentioned we are dealing with Int (integers) as Int age.

Please advise on this, it could be a silly question though but I am little confuse on this.

Hey Bhanu,

parseInt() is a method that belongs to the Integer class. In order to use this method, we must tell our program that we are grabbing it from the Integer class otherwise it wouldn't know where this method is coming from. What this method does is take a string value such as "5" and converts it into 5 (aka an actual number that we can now add/multiply/subtract/etc.). And then we store that number as our int age variable.

Does that make sense?

Hi Kevin,

I got the point and it does making some sense in my mind now.

Thanks for the clarity, the description given against my question was very simplistic & easy to understand.

Best Regards
