Does starting with an upper case means a different class or is the same?

Question

I'm asking because it says "Boolean", but in the code is "boolean"

Answer 1

Primite types are boolean, int, char etc

There's also wrapper classes which are basically classes that help you use methods on primitive types

For example, Integer wrapper class has a parseInt(); method
