Static class method vs declared class method?

So in this section, the instructor is making this character "letter" lowercase using the following:

letter = Character.toLowerCase(letter);

My question is whether or not Is this functionally any different from using:

letter = letter.toLowerCase(letter);

Kinda curious if it can reassign itself using it's own method here

I am assuming letter is a char. This is one of the Java primitives, not an object, so it has no member functions to invoke.

Character class wraps the primitive type char into a char object on which you can invoke methods.
