在VB.NET中使用IComparable进行石头、纸和剪刀游戏中的武器比较（同Java中的Comparable）

Question

我是编程和OOP的新手，所以请原谅我的知识不足。

作为我的岩石，纸和剪刀游戏的一部分，我想在VB.NET中创建一个抽象的超类（武器），它有子类（岩石，纸和剪刀）。我发现Java的等价物是：

 public abstract class Weapon implements Comparable<Weapon> {
    }



    public class Paper extends Weapon {

        @Override
        public int compareTo(Weapon o) {
            if (o instanceof Paper)
                return 0;
            else if (o instanceof Rock)
                return 1;
            return -1;
        }
    }

    public class Rock extends Weapon {

    @Override
    public int compareTo(Weapon o) {
        if (o instanceof Rock)
            return 0;
        else if (o instanceof Scissors)
            return 1;
        return -1;
    }
}

    public class Scissors extends Weapon {

    @Override
    public int compareTo(Weapon o) {
        if (o instanceof Scissors)
            return 0;
        else if (o instanceof Paper)
            return 1;
        return -1;
    }
}

我目前有以下资料：

Public MustInherit Class Weapons

Public Class Rock
    Inherits Weapons

    Public Function compareTo(ByVal Weapons As Object) As Integer


    End Function

End Class

Public Class Paper
    Inherits Weapons

    Public Function compareTo(ByVal Weapons As Object) As Integer

    End Function

End Class

Public Class Scissors
    Inherits Weapons

    Public Function compareTo(ByVal Weapons As Object) As Integer

    End Function

End Class

结束类

谁能好心地更正代码，以便可以比较岩石，纸和剪刀物体。如有任何帮助，将不胜感激。

谢谢

像这样：

Public Class Rock
    Inherits Weapons

    Public Function compareTo(ByVal Weapons As Object) As Integer
        If TypeOf Weapons Is Rock Then
            Return 0
        ElseIf TypeOf Weapons Is Scissors Then
            Return 1
        Else
            Return -1
        End If
    End Function
End Class

' etc.
