I’m lost!!! Please need help to understand better!! please

What the difference between private read only MapLocation[] _path and Maplocation [] _path = new Maplocation()

I might be wrong in the second example but I just to understand how can we create an array Maplocation if I don’t see anything in the class construct that can support that or can an array be created for any class?

I’m sorry for the confusing question. I am having a hard time understanding the difference between creating an object and doing the following: private read only MapLocation[] _path; Please help!!!!

Thank you!

You can create an array of any type object, both primitives and classes, just by using the brackets [].

But you have some other differences there, including access modifiers "private" and "read only".

And the code "Maplocation [] _path = new Maplocation()" would not be valid because it is trying to assign an array with a single item, even though they are the same type.

Are you saying that the type can essentially be whatever you want? For example it doesn't have to be string[], double[], int[] etc, but it can be named after a class?

Sure, you can have arrays of class objects. Like the one shown in the example (and in the video).
