C# enums 🪐

[@BroCodez]

using System; namespace MyFirstProgram { class Program { static void Main(string[] args) { // enums = special "class" that contains a set of named integer constants. // Use enums when you have values that you know will not change, // To get the integer value from an item, you must explicitly convert to an int // name = integer //Console.WriteLine(Planets.Mercury + " is planet #" + (int)Planets.Mercury); //Console.WriteLine(Planets.Pluto + " is planet #" + (int)Planets.Pluto); String name = PlanetRadius.Earth.ToString(); int radius = (int)PlanetRadius.Earth; double volume = Volume(PlanetRadius.Earth); Console.WriteLine("planet: " + name); Console.WriteLine("radius: " + radius +"km"); Console.WriteLine("volume: " + volume +"km^3"); Console.ReadKey(); } public static double Volume(PlanetRadius radius) { double volume = (4.0 / 3.0) * Math.PI * Math.Pow((int)radius, 3); return volume; } } enum Planets { Mercury = 1, Venus = 2, Earth = 3, Mars = 4, Jupiter = 5, Saturn = 6, Uranus = 7, Neptune = 8, Pluto = 9 } enum PlanetRadius { Mercury = 2439, Venus = 6051, Earth = 6371, Mars = 3389, Jupiter = 69911, Saturn = 58232, Uranus = 25362, Neptune = 24622, Pluto = 1188 } }

Hi! Could you make a video about topic "How to handle 2 keys pressed simultaneously in java"? Please... I'm Vietnamese and I'm really looking forward to this

[@Wojbest_YT]

nerds about to be like " 🤓um actually Pluto isn't a planet🤓"

[@whatdawhatgaming]

This is the best explanation of an enum I've come across. I knew exactly what is ACTUALLY was within the first 20 seconds. "A special type of class that contains a set of named integer constants." Literally a perfect explanation for me.

[@mttzern5457]

Hands down the best c# explanations there is in regards to value for time spent - much appreciated!!

[@NotTheHeroStudios]

I got so hyped when you put Pluto on that list.

[@jamiebertrand2669]

This helped a lot! I learned more in your 7 minute video than a 2 hour lecture!

Pluto is a planet

[@user-or6mz4gy6i]

I really loved how you casually listed the planets radius. I don't know if it was really from memory but if it was you deserve other props here in addition to your programming skill. By the way, are Enums a special type of class or struct. They felt closer to the second to me. Thanks!

[@user-or6mz4gy6i]

I have my answer. As structs, enums are value types and stored in the stack. They they feel closer to structs. But if you change "special type of class" by "special type of data structure" it is still valid. Thanks!

[@gameprogramming6550]

I have watched your almost all c# videos playlist. Thanks for the great content !!

[@rolfvanderbijl]

Great tutorial, clear, good examples and me is finally understanding why what I wanted to try didn't work. Thanks a lot!

[@nav3622]

I love you. You have helped me study for my midterms. I hope you get lots of happiness and success.

[@ranjanadissanayaka5390]

I was really curious about Enum. Thanks for the video Sir. 😀

[@atan6730]

Pluto is not a planet, ruined my immersion.... Nice explaining of ENUMs btw, keep up the good work ^^

[@SoDamnMetal]

Oh you're one of "those" guys huh? 🙄

[@mysteriousmop7686]

if (joke) { return funny; } else { return !funny; }

[@tymofii4718]

Amazing Explanation and super quick. Didnt need to speed it up like most tutorials

[@deepbule3517]

very clear and helpful. Thank you!

[@MoHaTa-u3f]

So basically "emun" is really good for values that have a name, like measurements for example. You could make a measurements enum with "foot = 12", and you could use either Measurements.foot; to state the name "foot", or do (int)Measurements.foot; to get the value of foot, which is 12

[@spartanranger]

Thanks for the video Bro.

[@McPatoo]

Helpful as always :) gigachad bro

[@ozknowledge4159]

superbe Thank you for this great tutorial

[@erikseberozvoj]

Great video bro! keep it up

[@curtislee1485]

You are also able to change the underlying data type used to store the values in an enum. ie change to use a byte, float, double etc. enum AnEnumUsingFloats : byte { SomeValue = 100, AnotherValue = 244 } Just remember to cast to the correct data type when you need to access the value.

This was helpful! thanks.

[@TIPSFIN]

i have a question. If i remove the points and zeroes before the number 4 and number 3 in my method, why does it fuck up my answer? This works: public static double CalculateBallVolume(double aRadius) { double volume = (4.0 / 3.0) * Math.PI * Math.Pow(aRadius,3); return volume; } This gives me a different answer that is not the volume of a sphere: public static double CalculateBallVolume(double aRadius) { double volume = (4 / 3) * Math.PI * Math.Pow(aRadius,3); return volume; } You can try it out yourself. (4.0 / 3.0) and (4 / 3) give different answers for some reason.

[@ajlakanen]

When both of the numbers are integers, the result will also be an integer. When at least one of the numbers is a double, the result will be double. Technically that's something called "operator overloading" -- that is, the division operator works a bit differently based on the types of the operands.

[@Commenter339]

great vid

[@zachnewby4739]

If you are having trouble, enums can't be member variables, meaning they can't go inside other classes.

[@LegendIke]

thanks king

[@fredrikandersson1538]

Solid ty

[@amplifiedge]

thank you bro!

[@asapboy1895]

This can be ran in java right? (Nice Work btw Bro)

[@ag4-z4z]

Thanks bro

[@linglingzhang8583]

i really like the way how you teach, if you are familiar with java framework, and make a tutorial for that, that will be great.!

[@welitonkira2830]

Thank you!

[@Cheboksarov]

Познавательно.

Thanks Bro!

[@nguyencanh8369]

thanks

[@giacomorinaldi]

hello Bro, i have one question: why you wrote in this way the method ? public static double Volume(PlanetRadius anyvariable) { double volume = (4.0 / 3.0) * Math.PI * Math.Pow((int)anyvariable, 3); return volume; } i dont understand why you put PlanetRadius in the method. please could you help me ?

[@jessiebessie3616]

So can we use Planet enum to fetch corresponding values in Planetradius enum directly?

[@AliTahreiSh]

What is the difference between Enum and Dictionary?

[@emilyalbert3366]

you can update, add, and change values in a dictionary

[@plebaroni3495]

YEEEESSSS PLUTO LETS FUCKING GOOO!!!

[@xwoken]

nice

[@fruitfunfitness3584]

I was surprised that your double ended up with a non integer value when it was calculated with an int, without casting the int into double. I suppose Math.pow is casting it.

[@triodit]

if pluto is a planet, then there are over 30,000 planets in the solar system....

[@zachdavis6624]

I was a little confused by the way you passed in radius there at the end, but that might just be my inexperience in C#

[@satyamshankar5459]

great!

[@marajruno]

"Pluto is a planet" sounded like Jerry Smith 😀

[@DetCoAnimeFan]

Java and C# enums are so much similar that it is confusing me.

[@dakar_84]

C# really similar to Java itself

[@abdurahmon9926]

real gigachad

[@nulzn8691]

I though it was going to be a bigger debate about whether Pluto is a planet or not 😅

[@Lonchanick]

I find barely useful the enums utility ... that could be done with a class right?

[@davidtummers8310]

WROOOOOONG! Pluto isn't a Planet anymore (sadly😢)

[@whitedinamo]

lesson check😇

Pluto is a planet

i know that i shouldn't be focusing on this but pluto is not a planet

why u have pluto in there UNSUBSCRIBED !
