Apologies for the poor formatting. I don’t know how to make my double enters show up.

I am having difficulty understanding how fields and objects relate to each other. I find it helpful when these concepts are related to concepts which I am already familiar with. For example, relating a field to a variable. This is done in the explanation that I took from exercise and typed out below:

"Create fields like this:

class Forest {
public string name;
public int trees;
}

This might look similar to defining a variable. It is! Each field is a variable and it will have a different value for each object."

The problem is that it seems to me that the concept of object was also related to a variable in an example and explanation from the previous exercise.

This example states that ‘phrase’, a variable, is an instance of string. To me the use of the words ‘instance of string’ suggests that phrase is an object of string.
I say this because the definition of object involves the words ‘instance of a class’ and class is contrasted to the custom data types like string.

I hope this makes sense so far. Could someone please explain why I am wrong about ‘phrase’ being an object of string.

Also, if class relates to data types, and fields relate to variables, then what are objects? The values assigned to the variables?

Thank you so much if you took the time to read this.
