So if you think about a method that is dependent on some value of a property of a class. Let's take a car for an example. You may have a public void Start() method. But this method may be dependent on the property public EngineType EngineType { get; set; }. This would be stateful because you can't perform that action without some knowledge about the object.

sorry but I don't know what {get; set} do yet

But let's say you have a Math class, with a method public int Add(int a, int b). This method does not depend on any other properties of the object and can be performed without knowledge of anything outside of the method.

Just ignore that part, then, it's just a property

it needs a and b

But those are provided when the method is called. It doesn't depend on any current state of the Math object

Let's say your Math class has a property name public int MyFavoriteNumber. The value of that property does not matter. It is not needed for the Add method

how can something be an object and class anyway? class is a category of somethings, object is something

like it doesn't make sense

a class is sort of like a set of rules for a type of thing. The object is the thing itself. Like the definition of a class might include something like a Color, Make, Model, and Year. That would be the class.

The object would be the actual instance of Car. So like a Red 1999 Ford Escort

so it does not depend on other properties of that class

not object

or is every class an object since it's an instance of itself?

no, a class is not an object

Though when I said "properties of the object", I mean that the properties of an object can actually have values. Properties of a class are just definitions of properties, usually don't have values

But that's kind of veering off course

so stateful methods get other values out of their class or somewhere else, but not from themselfs
stateless methods are 'self sufficient'

Stateful methods are dependent on the state of the object. Like my 1999 Ford Escort example. The Start() method might perform differently for that instance of Car versus a 2022 Tesla Model 3

what objects?

Im talking about methods

You're talking about methods dependent on object states

I'm asking about stateless and stateful methods

Correct

in other words, you're asking about methods that don't depend on object state versus methods that do depend on object state

what objects?

inside or outside of methods?

objects of the class that the method is contained in

you can't randomly store state inside a method as such.

you'll need either an object or a static variable to store that data in

what state?

ANY state

methods are sets of actions, not states

exactly

By state, we mean the state of the object. Or to word it differently, all of the values of all of the fields and properties at a given moment. That is it's state

so you cant store state (aka data that lives longer than a single execution of a method) in them

so object contains all of the values of their fields?

we've been over this in your previous threads, yes

Properties more specifically, but yes

I thought propeties were values?

properties hold values

could you give me an example of stateless and stateful methods please?

properties and fields are both just variables, but named a little different to describe how/where they're used

I thought they were the same

both are stored in a class

Consider these two classes and methods

the top one is entirely stateless. any two executions given the same values in will return the exact same value out

Consider what?

read the code?

they're both classes
