2. Do I need to create a construtor like below

You don't necessarily need a constructor like this. Instead, you could simply create an object then set the properties. However, constructors like this offer both convenience and also the notion of object validity. In other words, you can force someone to provide the information that you want by requiring them to use a constructor that takes the information.

could You please write some code regarding this, I meant how should I add customers with out using a constructor.

Thanks
