How does "if (equals(other))" work?

How does this work?

if (equals(other))

I get that we are checking if the current instance of Treet is equal to another Treet instance called "other", but why don't we have to specify what we are comparing "other" to?

that can be written also as:

if (this.equals(other))

So essentially we are comparing the current object with the "other" object.

I was googling around for literally half an hour since I couldn't grasp what we are actually comparing in the compareTo method... Your simple "this." addition finally helped to make sense of all of it.
