I want an attribute to increment each time an instance is created.

Everytime a new instance of Sleutel is made I want the _aantalInOmloop to increment.

Marked numbers is what the output should be

Angius•7mo ago

Make the _antalOolOop static and increment it in the ctor Ah, you already have it this way Well, it should work, then

REPL Result: Success

class Foo

    public static int Count { get; private set; } = 0;

    public Foo()

        Count++;
    }

var f = new Foo[]{new(), new(), new(), new(), new()};

Foo.Count

Like so

Alltman•7mo ago

           public static int AantalInOmloop{get; set;}

           public Sleutel(string naam, double gewicht, int niveau, int deur): base(naam,gewicht, niveau)
           {
               Deur = deur;
               AantalInOmloop++;
           }

           public static int AantalInOmloop{get; set;}

           public Sleutel(string naam, double gewicht, int niveau, int deur): base(naam,gewicht, niveau)
           {
               Deur = deur;
               AantalInOmloop++;
           }

like this A sleutel is a key btw but output is still key one... there are 2 keys, key two... there are 2 keys it needs to be key one... there is 1 key, key 2 ... there are 2 keys

Output? Keys? What do you mean?

Create the domain class "Tool": -3 properties: name (mandatory, may not be changed), weight (in kg) and level (int) -constructor with 3 parameters (controls see description setter) -constructor with 2 parameters. Level is set to 1 by default here. -getter for each attribute -setter for the attribute:◦weight: must be a positive number, less than 1000 kg◦level: there are 10 levels in the game, numbered from 1 to 10◦no setter for name because name may not be changed. Name may not be null or empty. -ToString Object ... with weight ... (3 digits after comma) kg from level ... Create 2 subclasses: The class "Weapon": -2 extra attributes: force and used -constructor -getters for the extra attributes -setter for each extra attribute:◦force: is a positive number◦used: no check needed -weapons are only available in levels 1 through 5: provide a CheckLevel method for this -ToString (see below for the requested output) The class "Key": -2 extra attributes: door (int), number of the door to which the key fits and numberInOverflow:represents the number of keys present in the game -constructor -getters for the extra attributes -setter for door: must be a positive number -ToString (see below for the requested output) -method PastOp: returns true/false depending on the current key on the door given as a parameter fits or not Cui layer Write an ObjectApplication in which an array of Weapons and an array of Keys are created. Let the application display the objects created.Possible output: Weapon colt with weight 1,500 kg from level 3 and with force 6 not yet used. Weapon brown with weight 0,500 kg from level 1 and with force 23 already used. Key front door with weight 0,500 kg from level 3 fits on door 1. There are 1 key(s) in circulation. Key back door with weight 0,500 kg from level 1 fits on door 2. There are 2 key(s) in circulation. this is the assignment Expected output: Key front door with weight 0,500 kg from level 3 fits on door 1. There are 1 key(s) in circulation. Key back door with weight 0,500 kg from level 1 fits on door 2. There are 2 key(s) in circulation. Current output: Key front door with weight 0,500 kg from level 3 fits on door 1. There are 2key(s) in circulation. Key back door with weight 0,500 kg from level 1 fits on door 2. There are 2 key(s) in circulation.

If you print all of that output after creating two keys, then that's how it'll look But still, not sure why you even need that property Why not just... keep the keys in a list? And count how many keys are in that list?

Alltman•7mo ago

That would be easy but sadly enough that's not the assignment 😦

Angius•7mo ago

Write an ObjectApplication in which an array of Weapons and an array of Keys are created.

Isn't it?

What is the command again to send my code? I will do it likethat
