Get list of attributes of an object in an List

Question

When there is an List, is there a possibility of getting List of all person.getName() out of that? Is there an prepared call for that

Answer 1

I think you will always need to do that. But if you will always need such things, then I would suggest to make another class, for example call it People where personList is a variable.

Something like this:

class People{
    List personList;
    //Getters and Setters

    //Special getters
    public List getPeopleNames(){
         //implement your method here        
    }

    public List getPeopleAges(){
         //get all people ages here
    }
}

In this case you will need to call one getter only each time.
