I am a complete ROOKIE at this so I need some help on it.
How would you create uml class diagram and constructors with parameters.
for default (no parameters) you do
policyholder() for diagram and pseudo-code
for 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)
回答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.
