我已经使用 ArgoUML 创建了一个 ERD（实体关系图），并且希望在一个类中创建两个操作，它们都具有 void 返回类型。但是，我只能创建一个返回 void 类型的操作。
例如：
我可以设置 bookInitial() 的返回类型到 void 但每当我尝试将 bookFollowUp() 的返回类型设置为 void 时，该选项不可用。
在检查了项目中的其他类后，似乎每个类只允许一个对象具有 void 返回类型 - 对于所有类都是如此吗？
有没有一种方法可以将 void 返回类型分配给多个操作？
谢谢。
I have created an ERD (Entity-Relationship Diagram) using ArgoUML and I wish to create two operations within a class which both have a void return type. However, I am only able to create one operation which returns a void type.
For example:
I am able to set the return type of bookInitial() to void but whenever I try to set the return type of bookFollowUp() to void, the option is not available.
Having checked with other classes in the project, it would appear that each class only allows one object to have a void return type - is this true for all classes?
Is there is there a way to assign the void return type to more than one operation?
Thank you.

ArgoUML是一个UML建模工具，因此它没有ER图。您可能正在使用 UML 类图。
您使用什么版本的 ArgoUML？如果这确实不起作用，并且您正在运行最新版本（0.32.2），那么这听起来像是一个错误，应该在 http://argouml.tigris.org/project_bugs.html
ArgoUML is a UML modeling tool, so it doesn't have E-R diagrams. You were probably working with UML Class Diagrams.
What version of ArgoUML are you using? If that really doesn't work, and you're running the latest version (0.32.2), it sounds like a bug which should be reported at http://argouml.tigris.org/project_bugs.html
我在创建两个返回 void 的操作时没有问题（使用 Argo v.0.24）。事实上，当添加新操作时，它们被创建为默认返回 void
I have no problem in creating two operations that return void (with Argo v.0.24). In fact, when adding new operations they are created as returning void by default
