constructor with parameters in UML class diagram

Question

How would you create an uml class diagram for constructors with parameters?

For default constructors (no parameters) you do

• policyholder() for the diagram and in the pseudo-code

For constructors with parameters would you do the same thing:

• policyholder (policynumber, service class, and customer age) for class diagrams and pseudo-code.

It also asked to initialize each attribute to value where an object of this type can be instantiated. If a policy number is not between 1000 and 999 inclusive, then set the policy number to 0. (policy number is attribute)

Answer 1

The common way is to write constructors like methods and simply omit the return type.

If you want to be extra clear, you can add <<constructor>> in front.
