[英]Using IComparable in vb.net for comparing weapons for Rock, Paper and Scissors game (same as Comparable in JAVA)
I'm new to programming and OOP so please forgive me for my lack of knowledge. 我是编程和OOP的新手,请原谅我的知识不足。
As part of my Rock, Paper and Scissors game I would like to create a abstract superclass (Weapon) which has subclasses (Rock, Paper and Scissors) in VB.NET. 作为我的Rock,Paper和Scissors游戏的一部分,我想创建一个抽象超类(武器),该类在VB.NET中具有子类(Rock,Paper和Scissors)。 I found the JAVA equivalent which is:
我发现等效的JAVA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;
}
}
I currently have the following: 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
End Class 末级
Could someone kindly correct the code to so that can compare Rock, Paper and Scissors objects. 有人可以将代码更正为以便可以比较Rock,Paper和Scissors对象。 Any help would be greatly appreciated.
任何帮助将不胜感激。
Thanks 谢谢
Like this: 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.
