C# getters and setters encapsulation tutorial example explained
#C# #getters #setters
//getters & setters = add security to fields by encapsulation
// They're accessors found within properties
// properties = combine aspects of both fields and methods (share name with a field)
// get accessor = used to return the property value
// set accessor = used to assign a new value
// value keyword = defines the value being assigned by the set (parameter)

I tried to run this code but it shows value hasn't been declared! Can you please explain how did you run it?

I just read 15 pages over this concept and walked away more confused than before I started. You explain concepts in such a beginner-friendly way and don't include a lot of random unnecessary stuff. I really appreciate you and the content you make. I feel like a lot of programmers have been coding for so long that they forget to slow down a bit when teaching people.

Yea, i understand now, like... now i know what is an namespace, what is a class, methods, etc etc... , but i remember when i started and ask: "TF is that", so we need to be humble and put ourselves in the place of those who are starting.

This really helped me understand. It seems like getters and setters can be described as: Do this when someone GETS the variable. Do this when someone SETS the variable.

Just went through a 2 hour C# course, and it ended right after he showed us classes, fields, and constructors. I don’t think properties and getters/setters were even mentioned.. So, going along with another tutorial, I was very perplexed when he put in { get; set; }. I tried to read the documentation online, but just confused myself even more. Your 4 minute video explained it well enough for me to completely understand it, so thank you!!

I don't understand the difference. If we wanted to limit the editing of the field "speed" by making it private, aren't we allowing it with the set property? In the end, we are allowing editing of speed. I'm a complete beginner, just to note.

@cranebird1467 Жыл бұрын

set&get are methods so you can create only get without set in this case field become read-only.

but if you create a unique getter and setter and only programm that the value is set to the value the function gets or returns the current value, than its not different than without using getters and setters, isnt it?

example to my other comment, I just seen something like this private int _progress; public int progress { get { return rank == 8 ? 0 : _progress; } set { rank += value / 100; _progress = value % 100; } }

2:57 no need for the else statement because if the "if" statement fails it'll just skip it and execute any code that is after the statement. Other than that pretty cool video

well for this example, he wants to make sure that the speed doesn’t go over 500 right?

I am not sure why my code/comment disappeared so i write again, but I just wanted to note the private variable + getter/setter does not have to be the same name like private speed and public Speed... I just seen a code where the variable was called _rank and rank, so it is just about your coding style

@Cruz0e 2 жыл бұрын

so they do not have to share the same name

@pieteb_nl 2 жыл бұрын

Puzzeled you can just use 'speed' in the setter, without defining it as a method parameter. This wouldn't be possible in java.

when you make the car object and give its speed you still can make the speed greater than 500, i would like to know how to limit this as well eg: Car car1 = new Car(500000);

Put the same logic as your setter in your constructor where you set Speed = speed

Do we need private field per each property? Or not

@sok8557 2 жыл бұрын

properties should be public while the fields the properties access should be private (doesnt always have to be, but if you want to apply encapsulation to the fields and use the get set accessors then properties should be public while fields should be private)

@sok8557 2 жыл бұрын

honestly rambled on a lot but tdlr: property: public while field = private (the reason for the property)
