Syntax for the compareTo() method

In the int compareTo() method, Craig uses this syntax to compare the current object with the passed-in object: if (equals(other))

I thought you refer to the object/instance which is calling your method with the 'this' keyword - so something like if(this.equals(other)) makes sense. In fact, this is what I used in the challenge and it passed.

So what's the difference between the two syntax-es? Does the first one implicitly call 'this' or is it something else I'm not aware of?

Hey Manish,

They are both the same thing. Even if you dont write the this keyword, it's automatically implied
