Integer.parseInt() use.

I understand why we need to change a string to an integer, but I don't fully grasp what the reasoning for this code is. What is the "Integer" part for in the beginning of this code?

Hi Adam,

The Integer class, in Java, is something called a wrapper class. A wrapper takes a primitive data type such as an integer and wraps it in an object.

The Integer part is needed because we are using the Integer class -- parseInt() is a method that's part of the Integer class.

Here are some external resources that you may want to read:
