Meaning of initialize?

Question about the task

Resolved

OK my understanding of the phrase: The class must have a constructor that takes a weight and color as arguments, and initializes all variables except the name and address. Meant to create something like: Cat(int weight, String color) this.color = color; this.weight = weight; age = 5; .. etc. EXCLUDING address and name since it's not supposed to be "initialized" However, I couldn't get my code to verify without putting: this.name = null; So clearly, I have no idea what initialize means.

I can't since I have verified it succesfully. I just didn't understand why it worked the way it did.

i think, u initialized field name in another place, so after creating object with this constructor, name was not null (default value of String)

So for example if in the top of my code I had written (before constructors) String name = "Mary"; Then later on I'd have to write null to prevent the name Sally from being written since we don't know the name of the homeless cat for example?

Exactly! Fields initializing in constructor take place after initializing in the creation moment. So, when u don't assign value to variable in constructor, variable get value from earlier context

Thanks so much Anton - that makes so much sense I don't know why I wasn't seeing that before, guess that's what happens when blindly entering code!
