java - 在 vb.net 中使用 IComparable 比较石头、剪纸和剪刀游戏的武器（与 JAVA 中的 Comparable 相同）

Question

我是编程和 OOP 的新手，所以请原谅我缺乏知识。

作为我的 Rock、Paper 和 Scissors 游戏的一部分，我想在 VB.NET 中创建一个具有子类（Rock、Paper 和 Scissors）的抽象超类（武器）。我找到了 JAVA 等价物：

 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;
    }
}

我目前有以下内容：

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

有人可以更正代码，以便可以比较 Rock、Paper 和 Scissors 对象。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.
